Do while loop in c#

Do While loop
Unlike for and while loops, which test the loop condition at the top of the loop, the do...while loop checks its condition at the bottom of the loop.
A do...while loop is similar to a while loop, except that a do...while loop is guaranteed to execute at least one time.

For Example:
using System;
class Program
{
    static void Main(string[] args)
    {
        /* local variable definition */
        int a = 0;

        /* do loop execution */
        do
        {
            Console.WriteLine("value of a: {0}", a);
            a = a + 1;
        } while (a < 10);

        Console.ReadLine();
    }
}
output will be:
