Can Console.Clear be used to only clear a line instead of whole console?

Description

You can use the Console.SetCursorPosition function to go to a specific line number. Then you can use this function to 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);
}

Sample

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

A simpler and imho better solution is:

Console.Write("\r" + new string(' ', Console.WindowWidth) + "\r");

It uses the carriage return to go to the beginning of the line, then prints as many spaces as the console is width and returns to the beginning of the line again, so you can print your own test afterwards.

"ClearCurrentConsoleLine", "ClearLine" and the rest of the above functions should use Console.BufferWidth instead of Console.WindowWidth (you can see why when you try to make the window smaller). The window size of the console currently depends of its buffer and cannot be wider than it. Example (thanks goes to Dan Cornilescu):

public static void ClearLastLine()
{
    Console.SetCursorPosition(0, Console.CursorTop - 1);
    Console.Write(new string(' ', Console.BufferWidth));
    Console.SetCursorPosition(0, Console.CursorTop - 1);
}

This worked for me:

static void ClearLine(){
    Console.SetCursorPosition(0, Console.CursorTop);
    Console.Write(new string(' ', Console.WindowWidth)); 
    Console.SetCursorPosition(0, Console.CursorTop - 1);
}
