一、 项目创建

• 项目使用软件Visual Studio 2022，并安装MvvmLight
  
• 项目使用数据库SQL Server2012下载和安装过程参考自https://www.32r.com/soft/4057.html，安装后管理员账号为sa，密码为自定义密码。

1. 数据库设置

• 建立ShoppingDB数据库，采用默认设置，建立Member表，字段为Id（主键int）、Name（nvarchar50）、Password（nvarchar50）、Level（nvarchar50）、InsertDate（datetime）
• Id字段设置为是标识 ，标识增量为1
  
• 数据库建立其他表与表结构如下
  

2. 数据库连接

• 在VS界面建立Entity(截图为DAL)文件夹，并添加ADO.NET实体，命名为ShoppingModel
• 选择来自数据库的EF设计器
  
• 新建连接，MicroSoft SQL Server。有可能提示缺少文件，点击下一步确定安装。
  
• 服务器名称检索不到的话可以直接输入. ，代表本地服务器。数据库名称可检索到刚建立的ShoppingDB
  
• 勾选是
  
• 勾选表，点击完成
  

3. 构造供货商Provider

• c#创建接口IProvider
• 设置接口IProvider为泛型，限制泛型为class
• 建立数据库的增删改查函数
  
• Entity增加ProvideBase类，设置为abstract类
• Entity增加MemberProvide类,继承自ProviderBase与IProvider，IProvider泛型为Member，实现接口

• 在ProviderBase类中定义字段 public ShoppingDBEntities db = new ShoppingDBEntities();
• 修改MemberProvider类，建立增删改查代码如下

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace 超市管理系统.Entity
{
    public class MemberProvider : ProviderBase, Iprovider<Member>
    {
        public int Delete(Member entity)
        {
            db.Entry(entity).State =System.Data.Entity.EntityState.Deleted;
            return db.SaveChanges();
        }

        public List<Member> GetAll()
        {
            return db.Member.ToList();
        }

        public int Insert(Member entity)
        {
            db.Entry(entity).State = System.Data.Entity.EntityState.Added;
            return db.SaveChanges();
        }

        public int Update(Member entity)
        {
            db.Entry(entity).State = System.Data.Entity.EntityState.Modified;
            return db.SaveChanges();
        }
    }
}

• Entity增加ProductProvider类,继承自ProviderBase与IProvider，IProvider泛型为Product
• 修改MemberProvider类，建立增删改查代码如下

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace 超市管理系统.Entity
{
    public class ProductProvider : ProviderBase, Iprovider<Product>
    {
        ProductProviderpublic int Delete(Product entity)
        {
            db.Entry(entity).State = System.Data.Entity.EntityState.Deleted;
            return db.SaveChanges();
        }

        public List<Product > GetAll()
        {
            return db.Product.ToList();
        }

        public int Insert(Product entity)
        {
            db.Entry(entity).State = System.Data.Entity.EntityState.Added;
            return db.SaveChanges();
        }

        public int Update(Product entity)
        {
            db.Entry(entity).State = System.Data.Entity.EntityState.Modified;
            return db.SaveChanges();
        }
    }
}

• 数据库其他表继承自ProviderBase与IProvider建立*****Provider对应的类，并增加增删改查代码。

二、 登录窗口

1. 窗口设置

• 数据库内Member表，点击编辑前200行可在界面增加内容，此处增加1，admin，123，9，null
• VS界面创建View文件夹，创建LoginView窗体，在ViewModel文件夹内创建LoginViewModel类，并继承ViewModelBase，ViewModelBase已实现消息通知
• 改造 ViewModelLocator类，在原内容基础上仿照MainViewModel的写法增加以下

public class ViewModelLocator
{
    public ViewModelLocator()
    {
        SimpleIoc.Default.Register<LoginViewModel>();
    }

    public LoginViewModel LoginViewModel
    {
        get
        {
            return ServiceLocator.Current.GetInstance<LoginViewModel>();
        }
    }
}

• LoginView.xaml内增加数据上下文来源 DataContext="{Binding Source={StaticResource Locator}, Path=LoginViewModel}"
• 在app.xaml中修改启动窗口为登录窗口 StartupUri="View/LoginView.xaml"
• 在根目录下创建类AppData.cs，并继承ObservableObject，使用懒汉Lazy模式，创造唯一实例
• AppData.cs创建属性 public Member CurrentUser { get; set; } = new Member();

public class AppData: ObservableObject
{
    public static AppData Instance{ get; set; } = new Lazy<AppData>(() => new AppData()).Value;
	public Member CurrentUser { get;  set; } = new Member();
}

• LoginViewModel.cs内创建的当前用户实体为只读属性 public AppData AppData => AppData.Instance;"
• 创建Member类的用户实体字段和属性

//默认放入账号和密码，用于调试
private Member member = new Member() { Name = "admin", Password="123"};
public Member Member
{
    get { return member; }
    set 
    { 
        member = value; 
        RaisePropertyChanged();
    }
}

• 创建登录按钮和退出按钮的命令
• LoginView.xaml界面的window命名loginView，按钮绑定命令使ElementName = loginView

        #region commands
        public RelayCommand<LoginView> LoginCommand
        {
            get
            {
                return new RelayCommand<LoginView>((view) =>
                {
                    if(string.IsNullOrEmpty(member.Name)&& string.IsNullOrEmpty(member.Password))
                    {
                        return;
                    }

                    var list = memberProvider.GetAll();
                    var model = list.FirstOrDefault(t => t.Name == member.Name && t.Password == member.Password);
                    if (model != null)
                    {
                        AppData.CurrentUser = model;
                    }
                    else
                    {
                        MessageBox.Show("用户名或密码错误！");
                        new MainWindow().Show();
                    }
                });
            } 
        }

        public RelayCommand<LoginView> ExitCommand 
        { 
            get
            {
                return new RelayCommand<LoginView>((view) => 
                { 
                    view.Close();
                    //终止进程，退出当前代码
                    //Environment.Exit(0); 
                });
            } 
            set; 
        }
        #endregion

<Window x:Class="超市管理系统.View.LoginView"
        x:Name="loginView"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
        xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
        xmlns:local="clr-namespace:超市管理系统.View"
        mc:Ignorable="d"
        WindowStartupLocation="CenterScreen"
        DataContext="{Binding Source={StaticResource Locator}, Path=LoginViewModel}"
        Title="系统登录" Height="250" Width="450">
    
    <StackPanel VerticalAlignment="Center" HorizontalAlignment="Center" >
        <DockPanel>
            <TextBlock Text="用户名：" Width="50" VerticalAlignment="Center" Height="25"/>
            <TextBox x:Name="userNameTextBox" Text="{Binding Member.Name, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}" Width="100"/>
        </DockPanel>

        <DockPanel Margin="0 15 0 0">
            <TextBlock Text="密   码：" Width="50" VerticalAlignment="Center" Height="25"/>
            <TextBox x:Name="passwordTextBox" Text="{Binding Member.Password, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}" Width="100"/>
        </DockPanel>

        <StackPanel Orientation="Horizontal" HorizontalAlignment="Right" Margin="0 15 0 0">
            <Button x:Name="dengLu" Command="{Binding LoginCommand}" 
                    CommandParameter="{Binding ElementName=loginView}"
                    Content="登录" Width="60" Height="25"/>
            <Button x:Name="tuiChu" Command="{Binding ExitCommand}"
                    CommandParameter="{Binding ElementName=loginView}" 
                    Content="退出" Width="60" Height="25" Margin="30 0 0 0"/>
        </StackPanel>
    </StackPanel>
</Window>

• 由于在MvvmLight中已存在ViewModelBase，在ViewModel文件夹创建ViewModelBase2.cs，继承ViewModelBase
• 因MainView需显示当前登录用户，需重新在MainViewModel内同样写 public AppData AppData => AppData.Instance;" ，因此作出修改LoginViewModel和MainViewModel重新继承自ViewModelBase2 ，将 public AppData AppData => AppData.Instance;" 放在ViewModelBase2内，LoginViewModel删去该行代码，MainViewModel也不需要再写该行代码。

2. 优化登录页面布局

• 使用Colors Lite抓取素材颜色数值，作为背景色。
• 在AppData类内添加全局变量内容：系统名称、背景色、前景色。

        public Member CurrentUser { get; set; } = new Member();
        /// <summary>
        /// 超市名称
        /// </summary>
        public string Title => "馒头超市管理系统";
        /// <summary>
        /// 背景颜色
        /// </summary>
        public SolidColorBrush Background => new SolidColorBrush(Color.FromRgb(40, 53, 81));
        /// <summary>
        /// 前景颜色
        /// </summary>
        public SolidColorBrush Forgeround => new SolidColorBrush(Colors.White);

• LoginView.xaml界面的window.title、TextBlock的背景色并使用Effect、前景色都改为Bingding

<Window x:Class="超市管理系统.View.LoginView"
        x:Name="loginView"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
        xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
        xmlns:local="clr-namespace:超市管理系统.View"
        mc:Ignorable="d"
        Background="{Binding AppData.Background}"
        WindowStartupLocation="CenterScreen"
        ResizeMode="NoResize"
        DataContext="{Binding Source={StaticResource Locator}, Path=LoginViewModel}"
        Title="系统登录" Height="400" Width="800">
    
    
    <Grid>
        <Grid.RowDefinitions >
            <RowDefinition Height="150"/>
            <RowDefinition/>
        </Grid.RowDefinitions>

        <TextBlock Grid.Row="0" Text="{Binding AppData.Title}" VerticalAlignment="Center" HorizontalAlignment="Center" Foreground="White" FontSize="30">
            <TextBlock.Effect>
                <DropShadowEffect/>
            </TextBlock.Effect>
        </TextBlock>
        <StackPanel Grid.Row="1"  HorizontalAlignment="Center" VerticalAlignment="Top" >
        <DockPanel>
            <TextBlock Text="用户名：" Width="50" VerticalAlignment="Center" Foreground="{Binding AppData.Forgeround}" Height="25"/>
            <TextBox x:Name="userNameTextBox" Text="{Binding Member.Name, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}" Width="100"/>
        </DockPanel>

        <DockPanel Margin="0 15 0 0">
                <TextBlock Text="密   码：" Width="50" VerticalAlignment="Center" Foreground="White" Height="25"/>
            <TextBox x:Name="passwordTextBox" Text="{Binding Member.Password, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}" Width="100"/>
        </DockPanel>

        <StackPanel Orientation="Horizontal" HorizontalAlignment="Right" Margin="0 15 0 0">
            <Button x:Name="dengLu" Command="{Binding LoginCommand}" 
                    CommandParameter="{Binding ElementName=loginView}"
                    Content="登录" Width="60" Height="25"/>
            <Button x:Name="tuiChu" Command="{Binding ExitCommand}"
                    CommandParameter="{Binding ElementName=loginView}" 
                    Content="退出" Width="60" Height="25" Margin="30 0 0 0"/>
        </StackPanel>
    </StackPanel>
    </Grid>
</Window>

三、 系统开发

1.菜单设计

• 主界面采用两行布置，第二行为底部状态栏，绑定AppDate.Current.Name显示当前用户的登录名称
• 主显示区分三列，第一列为菜单栏，第二列分竖线，第三列为用户控件区域
• 网络下载开源字体库 https://fontawesome.com.cn/，http://doc.vrd.net.cn/fontawesome/cheatsheet/，使用方式展示在下面代码中。
• sln添加Style文件夹，新建RadioButtons.xaml，左侧一级菜单采用RadioButton设计，在RadioButtons.xaml设置Style，分别设计了Content和Tag的Style
• 设置触发器，鼠标移入背景色发生变化，代码如下：

<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
                    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
    <Style x:Key="MenuRadioButtonStyle" TargetType="RadioButton">
        <Setter Property="Foreground" Value="#eeefff"/>
        <Setter Property="FontSize" Value="16"/>
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="RadioButton">
                    <!--此时已将radio的模板形状设置为了border，将border的背景色绑定radiobutton背景色，触发器才会生效-->
                    <Border Background="{TemplateBinding Background}">
                        <Grid>
                            <Grid.ColumnDefinitions>
                                <ColumnDefinition Width="30"/>
                                <ColumnDefinition Width="auto"/>
                            </Grid.ColumnDefinitions>
                            <TextBlock Grid.Column="0" Text="{TemplateBinding Tag}" FontFamily="/Fonts/#FontAwesome" Margin="5"/>
                            <TextBlock Grid.Column="1" Text="{TemplateBinding Content}" Margin="5"/>
                        </Grid>
                    </Border>

                    <ControlTemplate.Triggers>
                        <!--触发器的目标是radiobutton的背景色-->
                        <Trigger Property="IsMouseOver" Value="True">
                            <Setter Property="Background" Value="red"/>
                        </Trigger>
                        <Trigger Property="IsMouseOver" Value="False">
                            <!--透明色-->
                            <Setter Property="Background" Value="Transparent"/>
                        </Trigger>
                        <Trigger Property="IsChecked" Value="True">
                            <Setter Property="Background" Value="Goldenrod"/>
                        </Trigger>
                    </ControlTemplate.Triggers>
                </ControlTemplate>
            </Setter.Value>
        </Setter>
    </Style>
</ResourceDictionary>

            </StatusBarItem>
            <StatusBarItem>
                <TextBlock Text="{Binding AppData.CurrentUser.Name}" />
            </StatusBarItem>
        </StatusBar>
    </Grid>
</Window>

2. 界面切换

• 在View文件夹创建UserControl用户控件IndexView.xaml代表首页界面，ViewModel文件夹创建IndexViewModel.cs，在ViewModelLocator中按格式添加IndexViewModel
• 采用相同的方法依次为每个菜单按钮完成上述操作

using CommonServiceLocator;
using GalaSoft.MvvmLight;
using GalaSoft.MvvmLight.Ioc;
using 超市管理系统.ViewModel;

namespace 超市管理系统.ViewModel
{
    public class ViewModelLocator
    {
        /// <summary>
        /// Initializes a new instance of the ViewModelLocator class.
        /// </summary>
        public ViewModelLocator()
        {
            ServiceLocator.SetLocatorProvider(() => SimpleIoc.Default);

            SimpleIoc.Default.Register<MainViewModel>();
            SimpleIoc.Default.Register<LoginViewModel>();
            SimpleIoc.Default.Register<IndexViewModel>();
            SimpleIoc.Default.Register<OrderViewModel>();
            SimpleIoc.Default.Register<CustomerViewModel>();
            SimpleIoc.Default.Register<GoodsViewModel>();
            SimpleIoc.Default.Register<InstorageViewModel>();
            SimpleIoc.Default.Register<OutstorageViewModel>();
            SimpleIoc.Default.Register<OrderDetailViewModel>();
            SimpleIoc.Default.Register<SettingViewModel>();
            SimpleIoc.Default.Register<MemberViewModel>();
            SimpleIoc.Default.Register<SupplierViewModel>();
        }
        /// <summary>
        /// 主窗口所用
        /// </summary>
        public MainViewModel Main
        {
            get
            {
                return ServiceLocator.Current.GetInstance<MainViewModel>();
            }
        }
        /// <summary>
        /// 登录窗口所用
        /// </summary>
        public LoginViewModel LoginViewModel
        {
            get
            {
                return ServiceLocator.Current.GetInstance<LoginViewModel>();
            }
        }
		///lambda
        public IndexViewModel IndexViewModel => ServiceLocator.Current.GetInstance<IndexViewModel>();
        public OrderViewModel OrderViewModel => ServiceLocator.Current.GetInstance<OrderViewModel>();
        public CustomerViewModel CustomerViewModel => ServiceLocator.Current.GetInstance<CustomerViewModel>();
        public GoodsViewModel GoodsViewModel => ServiceLocator.Current.GetInstance<GoodsViewModel>();
        public InstorageViewModel InstorageViewModel => ServiceLocator.Current.GetInstance<InstorageViewModel>();
        public OutstorageViewModel OutstorageViewModel => ServiceLocator.Current.GetInstance<OutstorageViewModel>();
        public OrderDetailViewModel OrderDetailViewModel => ServiceLocator.Current.GetInstance<OrderDetailViewModel>();
        public SettingViewModel SettingViewModel => ServiceLocator.Current.GetInstance<SettingViewModel>();
        public MemberViewModel MemberViewModel => ServiceLocator.Current.GetInstance<MemberViewModel>();
        public SupplierViewModel SupplierViewModel => ServiceLocator.Current.GetInstance<SupplierViewModel>();
        public static void Cleanup()
        {
            // TODO Clear the ViewModels
        }
    }
}

• 更新MemberView.xaml文件中的菜单Style、Name和Checked。

                <StackPanel Grid.Row="1">
                    <RadioButton x:Name="IndexView" Style="{StaticResource MenuRadioButtonStyle}" Content="首页" Tag="&#xf015;" Checked="View_Checked"/>
                    <RadioButton x:Name="OrderView" Style="{StaticResource MenuRadioButtonStyle}" Content="商品下单" Tag="&#xf217;" Checked="View_Checked"/>
                    <RadioButton x:Name="GoodsView"  Style="{StaticResource MenuRadioButtonStyle}" Content="商品管理" Tag="&#xf16b;" Checked="View_Checked"/>
                    <RadioButton x:Name="CustomerView"  Style="{StaticResource MenuRadioButtonStyle}" Content="顾客管理" Tag="&#xf2bc;" Checked="View_Checked"/>
                    <RadioButton x:Name="SupplierView"  Style="{StaticResource MenuRadioButtonStyle}" Content="供应商管理" Tag="&#xf0d1;" Checked="View_Checked"/>
                    <RadioButton x:Name="InstorageView"  Style="{StaticResource MenuRadioButtonStyle}" Content="入库管理" Tag="&#xf00b;" Checked="View_Checked"/>
                    <RadioButton x:Name="OutstorageView"  Style="{StaticResource MenuRadioButtonStyle}" Content="出库管理" Tag="&#xf0ce;" Checked="View_Checked"/>
                    <RadioButton x:Name="OrderDetailView" Style="{StaticResource MenuRadioButtonStyle}" Content="订单详情" Tag="&#xf1eb;" Checked="View_Checked"/>
                    <RadioButton x:Name="MemberView" Style="{StaticResource MenuRadioButtonStyle}" Content="用户管理" Tag="&#xf2be;" Checked="View_Checked"/>
                    <RadioButton x:Name="SettingView" Style="{StaticResource MenuRadioButtonStyle}" Content="系统设置" Tag="&#xf085;" Checked="View_Checked"/>
                </StackPanel>

• 通过Switch和反射的方法都可以实现点击进行切换

using System.Windows;
using System.Windows.Controls;
using 超市管理系统.View;

namespace 超市管理系统
{
    /// <summary>
    /// MainWindow.xaml 的交互逻辑
    /// </summary>
    public partial class MainWindow : Window
    {
        public MainWindow()
        {
            InitializeComponent();
        }

        private void View_Checked(object sender, RoutedEventArgs e)
        {
            //页面切换

            //if（）等同于如果 sender is RadioButton，
            //然后RadioButton radioButton = (RadioButton)sender;
            if (sender is RadioButton radioButton)
            {
                if (string.IsNullOrEmpty(radioButton.Name)) return;
                //第一种方法 通过switch进行导航
                //switch (radioButton.Name)
                //{
                //    case "IndexView":
                //        container.Content = new IndexView();
                //        break;
                //    case "OrderView":
                //        container.Content = new OrderView();
                //        break;
                //    case "CustomerView":
                //        container.Content = new CustomerView();
                //        break;
                //    case "GoodsView":
                //        container.Content = new GoodsView();
                //        break;
                //    case "InstorageView":
                //        container.Content = new InstorageView();
                //        break;
                //    case "MemberView":
                //        container.Content = new MemberView();
                //        break;
                //    case "OrderDetailView":
                //        container.Content = new OrderDetailView();
                //        break;
                //    case "OutstorageView":
                //        container.Content = new OutstorageView();
                //        break;
                //    case "SettingView":
                //        container.Content = new SettingView();
                //        break;
                //    case "SupplierView":
                //        container.Content = new SupplierView();
                //        break;

                //第二种方法 通过反射进行导航
                Type type = Type.GetType("超市管理系统.View." + radioButton.Name);
                container.Content = Activator.CreateInstance(type);
                }
            }
        }
    }
}
