showing percentage in .net console application

Print \r to get back to the start of the line (but don’t print a newline!)

For example:

using System;
using System.Threading;

class Test
{
    static void Main()
    {
        for (int i=0; i <= 100; i++)
        {
            Console.Write("\r{0}%", i);
            Thread.Sleep(50);
        }
    }
}
