7. 商品入库管理
- 数据库中StockRecord表需要增加商品出入库Type类型为nvarchar(50)。
- C#中的数据库重新同步StockRecord表
- 在Entity→Model中新建枚举类型StockType
csharp
namespace 超市管理系统.Entity.Model
{
public enum StockType
{
入库,
出库
}
}7.2 入库实现显示名称、图片、单位
- 由于StockRecord表内未设置商品名称，因此名称需要通过部分类实现。在Entity→Model中新建StockRecord:BaseModel。
csharp
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Media.Imaging;
using 超市管理系统.Entity.Model;
using 超市管理系统.Helper;
using 超市管理系统.ViewModel;
namespace 超市管理系统.Entity
{
public partial class StockRecord:BaseModel
{
public string ProductName
{
get
{
//ProductId为StockRecord表中的ProductId为StockRecord表中的
return ProductViewModel.productProvider.GetAll().FirstOrDefault(t => t.Id == ProductId).Name;
}
}
public BitmapImage BitmapImage
{
get
{
string image = ProductViewModel.productProvider.GetAll().FirstOrDefault(t => t.Id == ProductId).Image;
return ImageHelper.GetBitmapImage(image);
}
}
}
}7.3 界面设计
- 已有UserControl文件InstorageView.xaml，复用ProductView.xaml内容并修改相应内容。

- InstorageViewModel，需要设计商品列表和选择项，入库数量绑定StockRecord表中的Quantity。功能有入库和删除两个。
- 由于商品相关的ViewModel中private ProductProvider productProvider = new ProductProvider()为不同的实例，造成在入库后切换页面Load不会触发更新 。因此，将ProductViewModel创建的改为 public static ProductProvider productProvider = new ProductProvider();，其他相关ViewModel删除private ProductProvider productProvider = new ProductProvider()，采用ProductProvider .productProvider 调用。

- 备注：当前未实现删除入库数据时同步更新商品管理中的数量，等待后续处理。
