The do...while loop

This helps us execute a statement or a statement of block repeatedly until it evaluates the expression to false. In do...while statement, a block of statement executes first and then it checks the condition under while, which means a statement or block of statements that execute at least once.

Take a look at the following code:

private static void DoWhileStatementExample() 
{ 
WriteLine("do...while example"); 
Write("Enter repeatitive length:"); 
int length = Convert.ToInt32(ReadLine()); 
int count = 0; 
do 
    { 
        count++; 
        WriteLine(newstring('*',count));  
    } while (count < length); 
} 

In the preceding code snippet, the statement of the do block executes until the statement of the while block evaluates to false.
