How to use the GetLongLength method of array class in C#?

The GetLongLength method in C# gets a 64-bit integer that represents the number of elements in the specified dimension of the Array.

First, set the array.

long[,] arr2= new long[15, 35];

For a specified dimension of the array, set the index in the GetLongMethod() method like −

long len2 = arr2.GetLongLength(0);

Let us see the complete example.

Example

using System;
class Program {
   static void Main() {
      int[,] arr = new int[20, 30];
      int len = arr.GetLength(0);
      Console.WriteLine(len);
      long[,] arr2= new long[15, 35];
      long len2 = arr2.GetLongLength(0);
      Console.WriteLine(len2);
   }
}

Output

20
15
