Type.GetArrayRank() Method is used to get the number of dimensions in an array.
 

Syntax: public virtual int GetArrayRank ();
Return Value: This method returns an integer which contains the number of dimensions in the current type.
Exception: This method throws ArgumentException if the current type is not an array. 
 

Below programs illustrate the use of Type.GetArrayRank() Method:
Example 1:
 

csharp




// C# program to demonstrate the
// Type.GetArrayRank() Method
using System;
using System.Globalization;
using System.Reflection;
 
class GFG {
 
    // Main Method
    public static void Main()
    {
 
        try
        {
            // Declaring and initializing Type object
            Type type = typeof(int[,,,,, ]);
 
            // Getting the dimensions
            // using GetArrayRank()
            int rank = type.GetArrayRank();
 
            // Display the rank
            Console.WriteLine("ArrayRank is:  {0}", rank);
        }
 
        catch (ArgumentException e)
        {
            Console.WriteLine("The current type is not an Array");
            Console.Write("Exception Thrown: ");
            Console.Write("{0}", e.GetType(), e.Message);
        }
    }
}

Output: 

ArrayRank is:  6

 

Example 2: 
 

csharp




// C# program to demonstrate the
// Type.GetArrayRank() Method
using System;
using System.Globalization;
using System.Reflection;
 
class GFG {
 
    // Main Method
    public static void Main()
    {
 
        try {
 
            // Declaring and initializing Type object
            Type type = typeof(int);
 
            // Getting ArrayRank by
            // using GetArrayRank()
            int rank = type.GetArrayRank();
 
            // Display the rank
            Console.WriteLine("ArrayRank is :  {0}", rank);
        }
 
        catch (ArgumentException e)
        {
            Console.WriteLine("The current type is not an Array");
            Console.Write("Exception Thrown: ");
            Console.Write("{0}", e.GetType(), e.Message);
        }
    }
}

Output: 

The current type is not an Array
Exception Thrown: System.ArgumentException
