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