Merge two arrays using C# AddRange() method

CsharpProgrammingServer Side Programming

Firstly, set two arrays −

int[] arr1 = { 15, 20, 27, 56 };
int[] arr2 = { 62, 69, 76, 92 };

Now create a new list and use AddRange() method to merge −

var myList = new List<int>();
myList.AddRange(arr1);
myList.AddRange(arr2);

After that, convert the merged collection to an array −

int[] arr3 = myList.ToArray()

Let us see the complete code

Example

 Live Demo

using System;
using System.Collections.Generic;
class Demo {
   static void Main() {
      int[] arr1 = { 15, 20, 27, 56 };
      int[] arr2 = { 62, 69, 76, 92 };
      // displaying array1
      Console.WriteLine("Array 1...");
      foreach(int ele in arr1) {
         Console.WriteLine(ele);
      }
      // displaying array2
      Console.WriteLine("Array 2...");
      foreach(int ele in arr2) {
         Console.WriteLine(ele);
      }
      var myList = new List<int>();
      myList.AddRange(arr1);
      myList.AddRange(arr2);
      int[] arr3 = myList.ToArray();
      Console.WriteLine("Merged array..");
      foreach (int res in arr3) {
         Console.WriteLine(res);
      }
   }
}

Output

Array 2...
