C# program to reverse an integer array using a predefined method

Here, we are going to learn how to reverse an integer array using a predefined method in C#?
Submitted by Nidhi, on September 03, 2020

Here we will create an array of integer elements then we reversed the elements of the array using the Reverse() method of Array class.

Program:

The source code to reverse an integer array using the predefine method is given below. The given program is compiled and executed successfully on Microsoft Visual Studio.

//C# program to reverse an array 
//using the predefined method.

using System;

class Sample
{
    public static void Main()
    {
        int[] intArr = new int[5]{10,20,30,40,50};
        int loop = 0;

        Array.Reverse(intArr);
        
        Console.WriteLine("Array after Reverse() method: ");
        for (loop = 0; loop < intArr.Length; loop++)
        {
            Console.WriteLine("Element "+(loop+1)+" is "+intArr[loop]);
        }
    }
}

Output:

Array after Reverse() method:
Element 1 is 50
Element 2 is 40
Element 3 is 30
Element 4 is 20
Element 5 is 10
Press any key to continue . . .

Explanation:

In the above program, we created a Sample class that contains the Main() method. In the Main() method, we created an array of integers that contains 5 elements.

Array.Reverse(intArr);

Here we reversed the elements of array "intArr" using the Reverse() method of Array class and then print the reversed array on the console screen.
