How to Exit a Foreach Loop in C#

This guide will teach us how to exit a foreach loop in C#. This is yet another simple method, and there’s no complexity involved.

Let’s dive into this guide and see the implementation of this code.

Exit a foreach Loop in C#

There are two ways that you can use to exit a foreach loop or any other loop for that matter. Exiting from a foreach loop is the same as exiting from any other loop.

Both of these ways are very common, and they are the ones that are mostly used in many other languages as well. For instance, C, C++, Java, etc.

Either we can use the break method or the return method. Both of these ways can be used to exit a foreach loop.

Take a look at the following code.

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

namespace For_Each_Loop {
  class Program {
    static void Main(string[] args) {
      int[] numbers_arr = { 4, 5, 6, 1, 2, 3, -2, -1, 0 };  // Example Array

      foreach (int i in numbers_arr) {
        System.Console.Write("{0} ", i);
        Console.ReadKey();  // To Stay On Screen
        if (i == 3) {
          break;  // IF You want To break and end the function call
        }
      }

      foreach (int i in numbers_arr) {
        System.Console.Write("{0} ", i);
        Console.ReadKey();  // To Stay On Screen
        if (i == 2) {
          return;  // IF You want To break and end the function call
        }
      }
    }
  }
}

We use both break and return in the above code. All you need to do is write break; or return; inside the foreach loop according to your needs.
