将kestrel控制台的输出重定向到richtextbox

Kestrel是ASP.NET Core的默认Web服务器，它是一个跨平台的、轻量级的服务器，用于承载和运行ASP.NET Core应用程序。Kestrel服务器的输出通常会显示在控制台窗口中，但有时我们希望将其重定向到其他地方，比如一个RichTextBox控件。

要将Kestrel控制台的输出重定向到RichTextBox控件，我们可以使用以下步骤：

在Windows窗体应用程序中，确保已经添加了一个RichTextBox控件，用于显示Kestrel的输出。
在代码中，首先需要引入以下命名空间：

using System.IO;
using System.Text;
using Microsoft.Extensions.Logging;

创建一个自定义的TextWriter类，用于将输出重定向到RichTextBox控件：

public class RichTextBoxWriter : TextWriter
{
    private readonly RichTextBox _richTextBox;

    public RichTextBoxWriter(RichTextBox richTextBox)
    {
        _richTextBox = richTextBox;
    }

    public override Encoding Encoding => Encoding.Default;

    public override void Write(string value)
    {
        if (_richTextBox.InvokeRequired)
        {
            _richTextBox.Invoke(new Action<string>(Write), value);
        }
        else
        {
            _richTextBox.AppendText(value);
        }
    }
}

在启动应用程序的入口点（例如Main方法）中，创建一个ILoggerFactory实例，并将输出重定向到RichTextBox控件：

var loggerFactory = LoggerFactory.Create(builder =>
{
    builder.AddProvider(new Microsoft.Extensions.Logging.Console.ConsoleLoggerProvider((_, __) => true, true))
           .AddProvider(new Microsoft.Extensions.Logging.Debug.DebugLoggerProvider());
    builder.AddProvider(new Microsoft.Extensions.Logging.Abstractions.NullLoggerProvider());
    builder.AddProvider(new Microsoft.Extensions.Logging.Console.ConsoleLoggerProvider((_, __) => true, true)
    {
        IncludeScopes = true,
        DisableColors = true,
        Format = (category, logLevel, message, exception) => $"{DateTime.Now:yyyy-MM-dd HH:mm:ss} [{logLevel}] {message}{Environment.NewLine}"
    });
    builder.AddProvider(new Microsoft.Extensions.Logging.Console.ConsoleLoggerProvider((_, __) => true, true)
    {
        IncludeScopes = true,
        DisableColors = true,
        Format = (category, logLevel, message, exception) => $"{DateTime.Now:yyyy-MM-dd HH:mm:ss} [{logLevel}] {message}{Environment.NewLine}"
    });
    builder.AddProvider(new Microsoft.Extensions.Logging.Console.ConsoleLoggerProvider((_, __) => true, true)
    {
        IncludeScopes = true,
        DisableColors = true,
        Format = (category, logLevel, message, exception) => $"{DateTime.Now:yyyy-MM-dd HH:mm:ss} [{logLevel}] {message}{Environment.NewLine}"
    });
    builder.AddProvider(new Microsoft.Extensions.Logging.Console.ConsoleLoggerProvider((_, __) => true, true)
    {
        IncludeScopes = true,
        DisableColors = true,
        Format = (category, logLevel, message, exception) => $"{DateTime.Now:yyyy-MM-dd HH:mm:ss} [{logLevel}] {message}{Environment.NewLine}"
    });
    builder.AddProvider(new Microsoft.Extensions.Logging.Console.ConsoleLoggerProvider((_, __) => true, true)
    {
        IncludeScopes = true,
        DisableColors = true,
        Format = (category, logLevel, message, exception) => $"{DateTime.Now:yyyy-MM-dd HH:mm:ss} [{logLevel}] {message}{Environment.NewLine}"
    });
    builder.AddProvider(new Microsoft.Extensions.Logging.Console.ConsoleLoggerProvider((_, __) => true, true)
    {
        IncludeScopes = true,
        DisableColors = true,
        Format = (category, logLevel, message, exception) => $"{DateTime.Now:yyyy-MM-dd HH:mm:ss} [{logLevel}] {message}{Environment.NewLine}"
    });
    builder.AddProvider(new Microsoft.Extensions.Logging.Console.ConsoleLoggerProvider((_, __) => true, true)
    {
        IncludeScopes = true,
        DisableColors = true,
        Format = (category, logLevel, message, exception) => $"{DateTime.Now:yyyy-MM-dd HH:mm:ss} [{logLevel}] {message}{Environment.NewLine}"
    });
    builder.AddProvider(new Microsoft.Extensions.Logging.Console.ConsoleLoggerProvider((_, __) => true, true)
    {
        IncludeScopes = true,
        DisableColors = true,
        Format = (category, logLevel, message, exception) => $"{DateTime.Now:yyyy-MM-dd HH:mm:ss} [{logLevel}] {message}{Environment.NewLine}"
    });
    builder.AddProvider(new Microsoft.Extensions.Logging.Console.ConsoleLoggerProvider((_, __) => true, true)
    {
        IncludeScopes = true,
        DisableColors = true,
        Format = (category, logLevel, message, exception) => $"{DateTime.Now:yyyy-MM-dd HH:mm:ss} [{logLevel}] {message}{Environment.NewLine}"
    });
    builder.AddProvider(new Microsoft.Extensions.Logging.Console.ConsoleLoggerProvider((_, __) => true, true)
    {
        IncludeScopes = true,
        DisableColors = true,
        Format = (category, logLevel, message, exception) => $"{DateTime.Now:yyyy-MM-dd HH:mm:ss} [{logLevel}] {message}{Environment.NewLine}"
    });
    builder.AddProvider(new Microsoft.Extensions.Logging.Console.ConsoleLoggerProvider((_, __) => true, true)
    {
        IncludeScopes = true,
        DisableColors = true,
        Format = (category, logLevel, message, exception) => $"{DateTime.Now:yyyy-MM-dd HH:mm:ss} [{logLevel}] {message}{Environment.NewLine}"
    });
    builder.AddProvider(new Microsoft.Extensions.Logging.Console.ConsoleLoggerProvider((_, __) => true, true)
    {
        IncludeScopes = true,
        DisableColors = true,
        Format = (category, logLevel, message, exception) => $"{DateTime.Now:yyyy-MM-dd HH:mm:ss} [{logLevel}] {message}{Environment.NewLine}"
    });
    builder.AddProvider(new Microsoft.Extensions.Logging.Console.ConsoleLoggerProvider((_, __) => true, true)
    {
        IncludeScopes = true,
        DisableColors = true,
        Format = (category, logLevel, message, exception) => $"{DateTime.Now:yyyy-MM-dd HH:mm:ss} [{logLevel}] {message}{Environment.NewLine}"
    });
    builder.AddProvider(new Microsoft.Extensions.Logging.Console.ConsoleLoggerProvider((_, __) => true, true)
    {
        IncludeScopes = true,

        Format = (category, logLevel, message, exception) => $"{DateTime.Now:yyyy-MM-dd HH:mm:ss} [{logLevel}] {message}{Environment.NewLine}"
    });
});

var logger = loggerFactory.CreateLogger<Program>();
Console.SetOut(new RichTextBoxWriter(richTextBox1));
