Delete Lines

[0x01337]

With this you can delete x Lines from your C# consoleapplication.
Its very help and useful, so you mustn't redraw anything.

 public static void ClearLastConsoleLines(int count)
        {
            int cursorTop = Console.CursorTop;
            if ((count == cursorTop) || (count == 0))
            {
                Console.Clear();
            }
            else if ((count < cursorTop) && (count > 0))
            {
                string str = new string(' ', Console.WindowWidth * count);
                Console.SetCursorPosition(0, cursorTop - count);
                Console.Write(str);
                Console.SetCursorPosition(0, cursorTop - count);
            }
        }

Nice one

Here is one for a RichTextBox Control: (Sorry any mistakes)

public void LineEdit(int Line, string NewValue, bool Clear = false)
        {
            int LinesLengh = richTextBox1.Lines.Length;
            if (Line >= LinesLengh)
                MessageBox.Show("Error - Line don't Exsist!");
            else
            {
                string[] TempData = richTextBox1.Lines;
                TempData[Line] = NewValue;
                richTextBox1.Lines = TempData;
            }
            if (Clear)
                richTextBox1.Clear();
        }

Example usage:

LineEdit(1, "Wonder");

For console usage, I think you could just replace the: richTextBox1.Lines with Console.Lines
