C# do...while loop. The do and while keyword is used to create a do...while loop. It is similar to a while loop, however there is a major difference between them. In while loop, the condition is checked before the body is executed. It is the exact opposite in do...while loop, i.e. condition is checked after the body is executed.

29 mar 2010 · Do..while is the way to go when you want to run some code, check or verify something (normally depending on what happened during the execution of that code), and if you don't like the result, start over again.
The do while loop is the same as while loop except that it executes the code block at least once. Syntax: do. {. //code block. } while(condition); The do-while loop starts with the do keyword followed by a code block and a boolean expression with the while keyword.
The do-while loop is a post-tested loop or exit-controlled loop i.e. first it will execute the loop body and then it will be going to test the condition. That means we need to use the do-while loop where we need to execute the loop body at least once.
The C# do while statement executes one or more iterations as long as a condition is true. The following shows the syntax of the do while statement: do { // statement } while (expression); Code language: JavaScript ( javascript )
To make a do-while loop we use the do keyword. Then we write a block of code between { and } that should execute repeatedly. After that we use the while keyword to check a Boolean condition.
C# iteration statements (for, foreach, do, and while) repeatedly execute a block of code. You use those statements to create loops or iterate through a collection.
