How to Join Arrays in C# ?

Answer

To join arrays in C#, you can use the LINQ Concat method or Array.Copy method.

✐ Examples

1 Joining Arrays using LINQ Concat Method

In this example,

We create two arrays, arr1 and arr2.
We then use the Concat method from the LINQ library to concatenate arr1 and arr2 into a new array result.
The result array contains elements from both arr1 and arr2.

C# Program

using System;
using System.Linq;
class Program
{
    static void Main()
    {
        int[] arr1 = { 1, 2, 3 };
        int[] arr2 = { 4, 5, 6 };
        var result = arr1.Concat(arr2).ToArray();
        Console.WriteLine("Joined Array: " + string.Join(", ", result));
    }
}

Output

Joined Array: 1, 2, 3, 4, 5, 6

2 Joining Arrays using Array.Copy Method

In this example,

We create two arrays, arr1 and arr2.
We then use the Array.Copy method to copy elements of arr2 to the end of arr1.
The result is a new array result containing elements from both arr1 and arr2.

C# Program

using System;
class Program
{
    static void Main()
    {
        int[] arr1 = { 1, 2, 3 };
        int[] arr2 = { 4, 5, 6 };
        int[] result = new int[arr1.Length + arr2.Length];
        Array.Copy(arr1, result, arr1.Length);
        Array.Copy(arr2, 0, result, arr1.Length, arr2.Length);
        Console.WriteLine("Joined Array: " + string.Join(", ", result));
    }
}

Output

Joined Array: 1, 2, 3, 4, 5, 6
