前言

在WPF中添加模拟控制台，可以试试的看到最新的日志信息。但是普通的TextBlock只是纯粹的黑色，这次试试模拟彩色的控制台界面

环境

.net core 8.0
win10
visual studio 2022
Nuget
- CommunityToolkit.Mvvm
- HandyControl
- Microsoft.Extensions.DependencyInjectio

流内容

流内容官方文档

什么是流内容？简单来说就是好看的报纸。我们这里以HandyControl的实例为例

一个简单的控制台

xml 复制代码

<RichTextBox>
    <FlowDocument x:Name="FlowDocument">
        <Paragraph>
            <Run Text="Debug" Foreground="Black"/>
        </Paragraph>
        <Paragraph>
            <Run Text="Info"
                 Foreground="Green" />
        </Paragraph>
        <Paragraph>
            <Run Text="Warning"
                 Foreground="Yellow" />
        </Paragraph>
        <Paragraph>
            <Run Text="Error"
                 Foreground="Red" />
        </Paragraph>
    </FlowDocument>
</RichTextBox>

自动添加数据

无法添加数据模板

【流内容】这个是一个特殊的集合，是无法添加控件模板的

代码添加参数

在微软的官网文档中，有相对应的文档

如何：通过 Blocks 属性操作流内容元素

简单的案例

我们先搭建一个简单的案例

xml 复制代码

<UserControl x:Class="WpfApp.Views.ConsoleView"
             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

             d:DesignHeight="450"
             d:DesignWidth="800">

    <UserControl.DataContext>
        <viewModels:ConsoleViewModel x:Name="ViewModel" />
    </UserControl.DataContext>
    <DockPanel>
        <StackPanel DockPanel.Dock="Top"
                    Orientation="Horizontal">
            <Button Content="Debug"
                    Margin="5"
                    Command="{Binding DebugCommand}" />
            <Button Content="Info"
                    Margin="5"
                    Command="{Binding InfoCommand}" />
            <Button Content="Warning"
                    Margin="5"
                    Command="{Binding WarningCommand}" />
            <Button Content="Error"
                    Margin="5"
                    Command="{Binding ErrorCommand}" />
            <Button Content="Clean"
                    Margin="5"
                    Command="{Binding CleanCommand}" />
        </StackPanel>
        <RichTextBox>
            <FlowDocument x:Name="FlowDocument">
                <Paragraph>
                    <Run Text="Debug" Foreground="Black"/>
                </Paragraph>
                <Paragraph>
                    <Run Text="Info"
                         Foreground="Green" />
                </Paragraph>
                <Paragraph>
                    <Run Text="Warning"
                         Foreground="YellowGreen" FontWeight="Bold" />
                </Paragraph>
                <Paragraph>
                    <Run Text="Error"
                         Foreground="Red" />
                </Paragraph>
            </FlowDocument>
        </RichTextBox>
    </DockPanel>
</UserControl>

csharp 复制代码

namespace WpfApp.Views
{
    /// <summary>
    /// ConsoleView.xaml 的交互逻辑
    /// </summary>
    public partial class ConsoleView : UserControl
    {
        public ConsoleView()
        {
            InitializeComponent();
            ViewModel.ConsoleView = this;
        }
    }
}

csharp 复制代码

namespace WpfApp.ViewModels
{
    public partial class ConsoleViewModel : ObservableObject
    {

        public enum TextType { debug, info, warning, error }

        public ConsoleView ConsoleView { get; set; }
        public ConsoleViewModel()
        {


        }

        [RelayCommand]
        public void Clean()
        {
        }
        [RelayCommand]
        public void Debug()
        {
        }
        [RelayCommand]
        public void Info()
        {

        }
        [RelayCommand]
        public void Warning()
        {


        }

        [RelayCommand]

        public void Error()
        {


        }
    }
}

效果

添加和清空功能

参考这个代码，但是我们需要修改一下对应的【Run】的颜色

csharp 复制代码

        /// <summary>
        /// 插入文本信息
        /// </summary>
        /// <param name="msg"></param>
        /// <param name="color"></param>
        private void InsertMsg(string msg, SolidColorBrush color)
        {
            var text = new Run(msg);
            text.Foreground = color;
            var insert = new Paragraph(text);
            ConsoleView.FlowDocument.Blocks.Add(insert);
        }
        [RelayCommand]
        public void Debug()
        {
        	//这里只是为了更好的区分，显示我们修改了颜色颜色
            InsertMsg("Debug",new SolidColorBrush(Colors.Red));
        }

清空直接用官方文档的方法就可以了

csharp 复制代码

        [RelayCommand]
        public void Clean()
        {
            ConsoleView.FlowDocument.Blocks.Clear();
        }

完善代码

csharp 复制代码

namespace WpfApp.ViewModels
{
    public partial class ConsoleViewModel : ObservableObject
    {

        public enum TextType { debug, info, warning, error }

        public ConsoleView ConsoleView { get; set; }
        public ConsoleViewModel()
        {


        }

        [RelayCommand]
        public void Clean()
        {
            ConsoleView.FlowDocument.Blocks.Clear();
        }
        [RelayCommand]
        public void Debug()
        {
            InsertMsg("Debug", new SolidColorBrush(Colors.Black));

        }
        [RelayCommand]
        public void Info()
        {
            InsertMsg("Info", new SolidColorBrush(Colors.Green));

        }
        [RelayCommand]
        public void Warning()
        {
            InsertMsg("Warning", new SolidColorBrush(Colors.YellowGreen));
        }

        [RelayCommand]

        public void Error()
        {
            InsertMsg("Error", new SolidColorBrush(Colors.Red));
        }

        /// <summary>
        /// 插入文本信息
        /// </summary>
        /// <param name="msg"></param>
        /// <param name="color"></param>
        private void InsertMsg(string msg, SolidColorBrush color)
        {
            var text = new Run(msg);
            text.Foreground = color;
            var insert = new Paragraph(text);
            ConsoleView.FlowDocument.Blocks.Add(insert);
        }
    }
}

额外功能添加

移动到底部

csharp 复制代码

/// <summary>
/// 插入文本信息
/// </summary>
/// <param name="msg"></param>
/// <param name="color"></param>
private void InsertMsg(string msg, SolidColorBrush color)
{
    var text = new Run(msg);
    text.Foreground = color;
    var insert = new Paragraph(text);
    ConsoleView.FlowDocument.Blocks.Add(insert);
    //滚动到文档底部
    ConsoleView.RichTextBox.ScrollToEnd();
}

添加样式

csharp 复制代码

/// <summary>
/// 插入文本信息
/// </summary>
/// <param name="msg"></param>
/// <param name="color"></param>
private void InsertMsg(string msg, SolidColorBrush color)
{
    var text = new Run(msg);
    //添加样式
    text.FontWeight = FontWeights.Bold;
    text.Foreground = color;
    var insert = new Paragraph(text);
    //添加样式
    insert.Margin = new Thickness(0, 5, 0, 0);
    ConsoleView.FlowDocument.Blocks.Add(insert);
    ConsoleView.RichTextBox.ScrollToEnd();
}

总结

这里我可以设置到Ioc容器里面，但是这样会导致博客太过于复杂，这里我就不展开说明了。
