The while statement, in C#, is an iteration statement that allows for the execution of an embedded statement conditionally for zero or more times. The embedded statement implies the code block that contains single or multiple statements to be executed within the while statement.
The while statement is one of the control flow statements in C# that enables the execution of a sequence of logic multiple times in a loop until a specific condition is false. Since the controlling expression that represents the condition is evaluated at the beginning of the execution of the while loop, there is a possibility of not entering the loop when the condition returns false in the first iteration.
The while statement is generally used when the number of iterations to be executed is not known and cannot be estimated. The while statement can also be used in a loop where the condition always remains true but there are exit conditions within the loop body statements.
