How to get the first element of an array in C#

In this tutorial, we are going to learn about how to get the first element of a array in C#.

Consider, we have the following array.

int[] arr = { 2, 4, 6, 8, 10};

Now, we want to get the first element 2 from the above array.

Getting the first element

To access the first element of an array, we can use the subscript syntax [] by passing the index 0 which is the index of the first element.

Note: In C# arrays are collection of items, where we can access it using the element index. where the first element index is 0, the second element index is 1, etc.

Here is an example :

using System;

class GetFirstElement {
  static void Main() {
   int[] arr = { 2, 4, 6, 8, 10};
    int firstElement = arr[0];
    Console.WriteLine(firstElement);
  }
}

Output:

2

Similarly, we can also use the Linq first() method in C# to get the first element of an array like this.

using System;
using System.Linq;

class GetFirstElement {
  static void Main() {
   int[] arr = { 2, 4, 6, 8, 10};
    int firstElement = arr.First();
    Console.WriteLine(firstElement);
  }
}
