Program:

The source code to find out the dimensions of the specified array is given below. The given program is compiled and executed successfully on Microsoft Visual Studio.

//Program to find out the dimensions of an array in C#

using System;

class Demo
{
    static void Main(string[] args)
    {
        int[]   OneD    = new int[10] ;
        int[,]  TwoD    = new int[3, 3];
        int[,,] ThreeD  = new int[2,3, 3];

        Console.WriteLine("Dimensions of OneD array is   : " + OneD.Rank);
        Console.WriteLine("Demensions of TwoD array is   : " + TwoD.Rank);
        Console.WriteLine("Demensions of ThreeD array is : " + ThreeD.Rank);
    }
}

Output:

Dimensions of OneD array is   : 1
Demensions of TwoD array is   : 2
Demensions of ThreeD array is : 3
Press any key to continue . . .

Explanation:

In the above program, we created three integer arrays OneD, TwoD, and ThreeD, and then we find out the dimensions of arrays using "Rank" property.
