How do you find the number of dimensions of an array in C#?

CsharpProgrammingServer Side Programming

To find the number of dimensions of an array, use the Rank property.

arr.Rank

Here, arr is our array −

int[,] arr = new int[3,4];

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

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

The following is the complete code −

Example

 Live Demo

using System;

class Program {
   static void Main() {
      int[,] arr = new int[3,4];

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

      // Length
      Console.WriteLine(arr.Length);
      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

3
4
12
Upper Bound: 2
Lower Bound: 0
Dimensions of Array : 2
