c# - Clear the current line, as with fflush(stdout) in C

Question

I have a very long for loop, which prints out many lines of information. I would like to keep it to just one line that overwrites previous lines. I tried Console.out.flush() but it does not seem to work.

Answer 1

Use

Console.SetCursorPosition

to get where the Cursor is at use

Console.CursorLeft
Console.CursorTop

Example

int i = 0;

Console.WriteLine("Numbers will count below this line");

int cLeft = Console.CursorLeft;
int cTop = Console.CursorTop;

while (true)
{
    Console.SetCursorPosition(cLeft, cTop);
    Console.WriteLine(i);
    i++;
}
