Bind Console Output to RichEdit

Question

So pretty straightforward question. I have a c# .dll with a whole lot of Console.Writeline code and would like to be able to view that output in a forms application using th

You can use Console.SetOut() to redirect the output. Here's a sample form that demonstrates the approach. Drop a RichTextBox and a button on the form.

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);
    }
}

I assume it won't be very fast but looked okay when I tried it. You could optimize by overriding more methods.
