Adding the elements of the specified collection to the end of the List in C#

To add elements of the specified collection to the end of the List, the code is as follows −

Example

 Live Demo

using System;
using System.Collections.Generic;
public class Demo {
   public static void Main(String[] args){
      List<string> list = new List<string>();
      list.Add("Andy");
      list.Add("Gary");
      list.Add("Katie");
      list.Add("Amy");
      Console.WriteLine("Elements in List...");
      foreach (string res in list){
         Console.WriteLine(res);
      }
      string[] strArr = { "John", "Jacob" };
      list.AddRange(strArr);
      Console.WriteLine("Elements in List...UPDATED");
      foreach(String str in list){
         Console.WriteLine(str);
      }
   }
}

Output

This will produce the following output −

Elements in List...
Andy
Gary
Katie
Amy Elements in List...UPDATED
Andy
Gary
Katie
Amy
John
Jacob

Example

Let us now see another example −

 Live Demo

using System;
using System.Collections.Generic;
public class Demo {
   public static void Main(String[] args){
      List<int> list = new List<int>();
      list.Add(25);
      list.Add(50);
      list.Add(75);
      list.Add(100);
      Console.WriteLine("Elements in List...");
      foreach (int val in list){
         Console.WriteLine(val);
      }
      int[] intArr = { 150, 200, 250, 300 };
      list.AddRange(intArr);
      Console.WriteLine("Elements in List...UPDATED");
      foreach(int val in list){
         Console.WriteLine(val);
      }
   }
}

Output

This will produce the following output −

Elements in List...
25
50
75
100
Elements in List...UPDATED
25
50
75
100
150
200
250
300
