Redirecting The Command-line To A Text Block

It involves inheriting from the StringWriter class, and overwriting it’s WriteLine function with your own code that writes the text to the text block (or any other text-capable object), rather than Windows writing it to the system console (whatever that may be).

Note that this code is suitable for passing into functions that require a System.IO.Stream, but this does not redirect messages that are being sent directly to the command line.

namespace StringRedirect
{
    /// <summary>
    /// Allows text blocks to appear like a command line for serial out string messages.
    /// </summary>
    public class TextBlockStreamWriter : StringWriter
    {
        private TextBlock _textBlock;

        public string Text
        {
            get
            {
                return _textBlock.Text;
            }
            set
            {
                _textBlock.Text += value;
            }
        }

        public TextBlockStreamWriter(ref TextBlock t)
        {
            _textBlock = t;
        }

        public override void WriteLine(string msg)
        {
            Text = msg + "\n";
        }
    }
}
