将控制台输出绑定到RichEdit

你可以用控制台放线()重定向输出。下面是一个示例表单,演示了该方法。在窗体上放置一个RichTextBox和一个按钮。

public partial class Form1 : Form {
    public Form1() {
        InitializeComponent();
        button1.Click += button1_Click;
        Console.SetOut(new MyLogger(richTextBox1));
    }
    class MyLogger : System.IO.TextWriter {
        private RichTextBox rtb;
        public MyLogger(RichTextBox rtb) { this.rtb = rtb; }
        public override Encoding Encoding { get { return null; } }
        public override void Write(char value) {
            if (value != '\r') rtb.AppendText(new string(value, 1));
        }
    }
    private void button1_Click(object sender, EventArgs e) {
        Console.WriteLine(DateTime.Now);
    }
}

在IMO看来,最好重构现有代码,替换现有代码 Console.WriteLine 这 TextWriter :

private static TextWriter output = Console.Out;
public static TextWriter Output {
   get {return output;}
   set {output = value ?? Console.Out;}
}
public static void WriteLine(string value) {
    output.WriteLine(value);
}
public static void WriteLine(string format, params string[] args) {
    output.WriteLine(format, args);
}

到你现有的代码中去写?
