Process output redirection on a single console line

Question

I am writing a C# application that can launch third party command line executables and redirect their standard output to a RichTextBox.

I am able to redirect the out

Answer 1

This code will fix up raw output and make it as it would appear on the terminal.

 //Deletes all lines that end with only a CR - this emulates the output as it would be seen cmd
public static string DeleteCRLines( this string Str) {
    Str = Str.Replace( "\r\r\n", "\r\n");
    //Splits at the CRLF. We will end up with 'lines' that are full of CR - the last CR-seperated-line is the one we keep
    var AllLines = new List( Str.Split( new[] {"\r\n"}, StringSplitOptions.None));
    for (int i = 0; i < AllLines.Count; i++){
        var CRLines = AllLines[i].Split('\r');
        AllLines[i] = CRLines[ CRLines.Count() -1];
    }
    return String.Join( Environment.NewLine, AllLines.ToArray());
}
