Can I Selectively Clear Specific Lines in the Console Using Console.Clear()?

Can Console.Clear() Be Used to Selectively Clear Specific Lines?

While working on a Q&A program for school, a developer encountered a dilemma with Console.Clear() erasing the entire screen indiscriminately. The question arose whether it was possible to utilize Console.Clear() to target specific lines, leaving the others intact.

Solution: Using Console.SetCursorPosition

Instead of relying solely on Console.Clear(), the developer can employ the Console.SetCursorPosition function to navigate to the desired line number. Once at the desired location, a custom function can be implemented to selectively clear the line:

public static void ClearCurrentConsoleLine()
{
    int currentLineCursor = Console.CursorTop;
    Console.SetCursorPosition(0, Console.CursorTop);
    Console.Write(new string(' ', Console.WindowWidth)); 
    Console.SetCursorPosition(0, currentLineCursor);
}

Example Usage:

To demonstrate how this method works, consider the following sample code:

Console.WriteLine("Test");
Console.SetCursorPosition(0, Console.CursorTop - 1);
ClearCurrentConsoleLine();

Resorting to methods like Console.SetCursorPosition provides flexibility and control over targeted line clearing, allowing the developer to retain specific content while selectively erasing obsolete information.
