do while Loop in C#

The do statement conditionally executes an embedded statement one or more times.

do-statement:
do   embedded-statement   while   (   boolean-expression   )   ;


A do statement is executed as follows:
  • Control is transferred to the embedded statement.
  • When and if control reaches the end point of the embedded statement (possibly from execution of a continue statement), the boolean-expression is evaluated. If the boolean expression yields true, control is transferred to the beginning of the do statement.
  • Otherwise, control is transferred to the end point of the do statement.

Within the embedded statement of a do statement, a break statement (§8.9.1) may be used to transfer control to the end point of the do statement (thus ending iteration of the embedded statement), and a continue statement may be used to transfer control to the end point of the embedded statement.

The embedded statement of a do statement is reachable if the do statement is reachable.

The end point of a do statement is reachable if at least one of the following is true:

  • The do statement contains a reachable break statement that exits the do statement.
  • The end point of the embedded statement is reachable and the boolean expression does not have the constant value true.
