Merge two arrays using C# AddRange() method

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 1... 15 20 27 56 Array 2... 62 69 76 92 Merged array.. 15 20 27 56 62 69 76 92
