Can I clear specific text from the console?

Question

I try to build a game and I always clear the screen but that makes it lag. So, to make it not lag, can I clear specific text?

If you want to remove only one last char then simply use console backspace \b char

Console.Write("\b");

If you want to clear only one char,You can use Console.SetCursorPosition(int, int) to reach that point then the write empty

Console.SetCursorPosition(Console.CursorLeft - 1, Console.CursorTop);
Console.WriteLine(" ");

To remove more than one char, you can store the current Console.CursorLeft in a variable and use that value in Console.SetCursorPosition(--variablename, Console.CursorTop) in a loop to delete many chars you want!

For Example:- if You want to delete Current Console Line Then

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

Console.WriteLine("Top 1 Line");
Console.WriteLine("Top 2 Line");
Console.WriteLine("Top 3 Line");
Console.SetCursorPosition(0, Console.CursorTop - 1);
ClearCurrentConsoleLine();

Then Output Will be only top 2 lines. third line will be deleted:-

Top 1 Line
Top 2 Line
