Algorithm

In C#, the break statement is used to exit a loop prematurely. It is typically used in for, while, and do-while loops to terminate the loop's execution based on a certain condition. The break statement immediately ends the loop and transfers control to the statement following the loop.

Code Examples

#1 C# Programming break statement with for loop

Code - C# Programming

using System;

namespace CSharpBreak {
  
  class Program {
    static void Main(string[] args) {

      for (int i = 1; i  < = 4; ++i) {
        
        // terminates the loop
        if (i == 3) {
          break; 
        }
            	
        Console.WriteLine(i);
      }
      	 
      Console.ReadLine();
      
    }
  }

#2 C# Programming break statement with while loop

Code - C# Programming

using System;

namespace WhileBreak {

  class Program {
    static void Main(string[] args) {
      int i = 1;
      while (i  < = 5) {
        Console.WriteLine(i);
         i++;
           if (i == 4) {
             // terminates the loop
             break; 
           }

Code - C# Programming

using System;

namespace NestedBreak {
  class Program {
    static void Main(string[] args) {

      int sum = 0;
      for(int i = 1; i  < = 3; i++) { //outer loop

      // inner loop
      for(int j = 1; j  < = 3; j++) { 
        if (i == 2) {
          break;
        }

      Console.WriteLine("i = " + i + " j = " +j);

      }
    }
	 
    Console.ReadLine();

#4 break with foreach Loop in C# progrram

Code - C# Programming

using System;

namespace ForEachBreak {
  class Program {
    static void Main(string[] args) {
      int[] num = { 1, 2, 3, 4, 5 };

      // use of for each loop
      foreach(int number in num) {

        // terminates the loop
         if(number==3) {
           break; 
           }

      Console.WriteLine(number);

#5 break with Switch Statement in C# Programming

Code - C# Programming

using System;

namespace ConsoleApp1 {

  class Program {
    static void Main(string[] args) {
      char ch='e';

       switch (ch) {
         case 'a':
           Console.WriteLine("Vowel");
           break;

         case 'e':
           Console.WriteLine("Vowel");
           break;

         case 'i':
           Console.WriteLine("Vowel");
           break;

         case 'o':
           Console.WriteLine("Vowel");
           break;

         case 'u':
           Console.WriteLine("Vowel");
           break;

         default:
