While Loop
A while loop is similar to a for-loop, however, it is used when we need to execute a block of code repeatedly based on a condition. The syntax of a while-loop is simpler than that of a for-loop:
Example:
main
using System; namespace ConsoleApp { internal class Program { static void Main(string[] args) { int i = 0; while(i < 5) { Console.WriteLine(i); i++; } } } }
The following diagram shows the execution process of a while loop:
Although the while loop may seem very similar to the for-loop at first, In more advanced levels of programming the difference becomes apparent. We might explore the usage of different kinds of loops in the Arrays section.
Tip:
We can write true
as the condition of a while-loop to create an infinite loop:
main
while(true) { Console.WriteLine("Hello World"); }
Everything was clear?
