How to check if an array is empty in C#

In this tutorial, we are going to learn about how to check if an array is empty or not in C#.

Checking the empty array

To check if an given array is empty or not, we can use the built-in Array.Length property in C#.

Here is an example:

using System;
class Check {
  static void Main() {
    int[] myArr = new int[] {};
    if (myArr.Length == 0) {
          Console.WriteLine("array is empty");
     }else{
         Console.WriteLine("array is not empty");
     }
 }
}

Alternatively, we can also use the Array.Length property to check if a array is null or empty in C#.

using System;
class Check {
  static void Main() {
    int[] myArr = new int[] {};
    if (myArr == null || myArr.Length == 0) {
          Console.WriteLine("array is empty");
     }else{
         Console.WriteLine("array is not empty");
     }
 }
}

Note: The string.Length property returns the total number of elements in a given Array.
