How to find the rank of an array in C#

Array.Rank Property is used to get the rank of the Array. Rank is the number of dimensions of an array. For example, 1-D array returns 1, a 2-D array returns 2, and so on.

Syntax:

public int Rank { get; }

Property Value: It returns the rank (number of dimensions) of the Array of type System.Int32.

Below programs illustrate the use of above-discussed property:

Example 1:



// C# program to illustrate the
// Array.Rank Property
using System;
namespace geeksforgeeks {
  
class GFG {
  
    // Main Method
    public static void Main()
    {
  
        // declares a 1D Array of string.
        string[] weekDays;
  
        // allocating memory for days.
        weekDays = new string[] {"Sun", "Mon", "Tue", "Wed",
                                      "Thu", "Fri", "Sat" };
  
        // using Rank Property
        Console.WriteLine("Dimension of weekDays array: " 
                                       + weekDays.Rank);
    }
}
}

Output:

Dimension of weekDays array: 1

Example 2:

// C# program to illustrate the
// Array.Rank Property
using System;
namespace geeksforgeeks {
  
class GFG {
  
    // Main Method
    public static void Main()
    {
  
        // declaring an 2-D array
        int[, ] arr2d = new int[4, 2];
  
        // declaring an 3-D array
        int[,, ] arr3d = new int[4, 2, 3];
  
        // declaring an jagged array
        int[][] jdarr = new int[2][];
  
        // using Rank Property
        Console.WriteLine("Dimension of arr2d array: " 
                                        + arr2d.Rank);
  
        Console.WriteLine("Dimension of arr3d array: " 
                                        + arr3d.Rank);
  
        // for the jagged array it 
        // will always return 1
        Console.WriteLine("Dimension of jdarr array: " 
                                        + jdarr.Rank);
    }
}
}

Output:

Dimension of arr2d array: 2
Dimension of arr3d array: 3
Dimension of jdarr array: 1
