What types of loops are supported in C#?

Csharp Programming Server Side Programming

A loop statement allows us to execute a statement or a group of statements multiple times. The following are the loops supported in C# −

Sr.No	Loop Type & Description
1	while loop It repeats a statement or a group of statements while a given condition is true. It tests the condition before executing the loop body.
2	for loop It executes a sequence of statements multiple times and abbreviates the code that manages the loop variable.
3	do...while loop It is similar to a while statement, except that it tests the condition at the end of the loop body

With C#, you can also use foreach loop as shown below −

Example

Live Demo

using System;

namespace Demo {
   class Program {
      static void Main(string[] args) {
         int [] n = new int[10]; /* n is an array of 10 integers */

         /* initialize elements of array n */
         for ( int i = 0; i < 10; i++ ) {
            n[i] = i + 100;
         }

         /* output each array element's value */
         foreach (int j in n ) {
            int i = j-100;
            Console.WriteLine("Element[{0}] = {1}", i, j);
         }
         Console.ReadKey();
      }
   }
}

Output

Element[0] = 100
Element[1] = 101
Element[2] = 102
Element[3] = 103
Element[4] = 104
Element[5] = 105
Element[6] = 106
Element[7] = 107
Element[8] = 108
Element[9] = 109
