Foreach Loop in C#

The foreach loop executes a statement or a block of statements for each element in an instance of the type that implements the System.Collections.IEnumerable or System.Collections.Generic.IEnumerable<T> interface.

Example

Let us see an example of foreach loop −

 Live Demo

using System;
using System.Collections.Generic;
public class Demo {
   public static void Main(){
      LinkedList<int> linkedList = new LinkedList<int>();
      linkedList.AddLast(25);
      linkedList.AddLast(50);
      linkedList.AddLast(100);
      linkedList.AddLast(200);
      linkedList.AddLast(400);
      linkedList.AddLast(500);
      linkedList.AddLast(550);
      linkedList.AddLast(600);
      linkedList.AddLast(800);
      linkedList.AddLast(1200);
      Console.WriteLine("Count of nodes = " + linkedList.Count);
      foreach(int val in linkedList){
         Console.WriteLine(val);
      }
      Console.WriteLine("Does the LinkedList has node 800? "+linkedList.Contains(800));
   }
}

Output

This will produce the following output −

Count of nodes = 10
25
50
100
200
400
500
550
600
800
1200
Does the LinkedList has node 800? True
