While Loop In C#

The while loop in C# iterates a block of code as long as the specified condition remains true. It's useful for repetitive tasks with dynamic termination criteria, providing flexible control flow in programming logic.

Introduction

In this blog, we will write a C# program for the While loop.

How does a While Loop Work?

• A C# while loop consists of a test expression.
• If the test expression is evaluated to be true,
  • A statement inside the while loop is executed.
  • After execution, the test expression is evaluated again.
• If the test expression is evaluated as false, the while loop terminates.

While Loop

The while loop is basically a programming structure that allows us to loop over a specific block of code while a certain condition is true. Basically, by using while loops, we're able to keep doing something repeatedly while a condition is true and this comes in handy in a bunch of situations. Loops are extremely useful in a programming language like C#, so let's get started.

The project is in C# Visual Studio.

This code sample shows that I will use a while loop in C# code.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace while_loop {
    class Program {
        static void Main(string[] args) {
            int number = 0;
            int target = 100;
            while (number < 100) {
                Console.WriteLine(number);
                number++;
            }
        }
    }
}

Save the program.

Now run the while loop C# code.

Click on the start button and debug the program.

Output to the While loop C# code.

I hope you understand how to use a While loop using C# Code.
