do (C# Reference) 

The do statement executes a statement or a block of statements enclosed in {} repeatedly until a specified expression evaluates to false. In the following example the do loop statements execute as long as the variable y is less than 5.

Example

// statements_do.cs
using System;
public class TestDoWhile 
{
    public static void Main () 
    {
        int x = 0;
        do 
        {
            Console.WriteLine(x);
            x++;
        }
        while (x < 5);
    }
}

Output

0
1
2
3
4

Remarks

Unlike the while statement, the body loop of the do statement is executed at least once regardless of the value of the expression.
