Foreach loops in C#

This tutorial explains how to use the foreach loop to go through each element in an array. A foreach loop is simpler and easier to use than a for loop if you want to loop through each and every element in an array. There is no need to use a counter, specify an increment, or a condition. The foreach loop will simply loop through every element in the array.

Foreach loops are written in a way that is easy to understand, for example:

foreach (string item in itemsList){
   Console.WriteLine(item);
}

Watch the video below and then scroll down for the sample code.

Sample code

using System;

namespace MyCSharpProject
{
  class Program
  {
    static void Main(string[] args)
    {
      // Create an array of string type
      string[] names = {"Jim","Kate","Sam","Sally"};

      // Store length of names array in variable
      int arrayLength = names.Length;

      // Go through each name in names array and display on new line
      foreach (string name in names) {
        Console.WriteLine(name);
      }
      // Wait for user input before quitting program
      Console.ReadLine();
    }
  }
}
