[C#] Redirect WriteLine stream to a textblock

Debug.WriteLine

// Release 모드로 .exe실행시 실행X, Debug모드 실행파일로 실행시 실행O

    class TextBoxTraceListener : TraceListener
    {
        private TextBox tBox;

        public TextBoxTraceListener(TextBox box)
        {
            this.tBox = box;
        }

        public override void Write(string msg)
        {
            //allows tBox to be updated from different thread
            tBox.Dispatcher.BeginInvoke(new Action(() =>
            {
                tBox.AppendText(msg);
            })
            );
        }

        public override void WriteLine(string msg)
        {
            Write(msg + "\r\n");
        }
    }

        {
        	InitializeComponent();
            TextBoxTraceListener tbtl = new TextBoxTraceListener(TextBox);//TextBox control 객체인자로 전달
            Debug.Listeners.Add(tbtl);

Redirect Debug.WriteLine stream to a textblock

Trace.WriteLine

// Release 모드에서 실행시 실행O, Debug모드 실행파일로 실행시 실행O

 

This allows you to distinct between several outputs. So you can use Console.Write for user output and trace for debuging purposes

Console.WriteLine

// Console에 출력.

public class TextBoxStreamWriter : TextWriter
    {
        TextBox _output = null;

        public TextBoxStreamWriter(TextBox output)
        {
            _output = output;
        }

        public override void Write(char value)
        {
            base.Write(value);
            _output.Dispatcher.BeginInvoke(new Action(() =>
            {
                _output.AppendText(value.ToString());
            })
            ); // When character data is written, append it to the text box. 
        }

        public override Encoding Encoding
        {
            get { return System.Text.Encoding.UTF8; }
        }
    }
    
    
    public partial class MainWindow : Window
    {
    	public MainWindow() //MainWindow class 생성자
        {
        	InitializeComponent();
            TextWriter _writer = null;
            _writer = new TextBoxStreamWriter(txList);
            Console.SetOut(_writer);
        }
    }
