While Loop in C#

The while loop executes a block of code while a boolean expression evaluates to true. It terminates as soon as the expression evaluates to false. The boolean expression is evaluated before each iteration.


Syntax
while (booleanExpression) { 
   //statements 
}

Notes

booleanExpression results in either a true or false output. It is created using comparing operators (==, >, =, <=, !=).

There can also be multiple boolean expressions within the parentheses (booleanExpression). The boolean expressions are connected through logical operators (&&, ||, !).

If the boolean expression result is true, the statements within the structure will be executed. They will continue to loop through the structure until the booleanExpression is false.


Example
int x = 0; 
while(timer < 10) { 
   Console.WriteLine(x); 
   x++;
}
