What does Array.Rank property of array class do in C#?

Let us see an example to find the number of dimensions of an array, using the Rank property.

arr.Rank

Here, arr is our array −

int[,] arr = new int[5,5];

If you want to get the rows and columns the array has, then use the GetLength property −

arr.GetLength(0);
arr.GetLength(1);

The following is the complete code −

Example

using System;

class Program {
   static void Main() {
      int[,] arr = new int[4,5];

      Console.WriteLine(arr.GetLength(0));
      Console.WriteLine(arr.GetLength(1));

      Console.WriteLine("Upper Bound: {0}",arr.GetUpperBound(0).ToString());
      Console.WriteLine("Lower Bound: {0}",arr.GetLowerBound(0).ToString());
      Console.WriteLine("Dimensions of Array : " + arr.Rank);
   }
}

Output

4
5
Upper Bound: 3
Lower Bound: 0
Dimensions of Array : 2
