C# Array.Reverse ExampleInvoke Array.Reverse, which reverses the order of elements. The array is modified in-place.
Array.Reverse. This .NET method inverts the ordering of an array's elements. This task could be accomplished with a for-loop. But Array.Reverse() is more convenient.
For
C# method info. The Array.Reverse method is a static method on the Array type. It is simple to use—we need the System namespace. It changes the array.

Static
Example. You should pass one argument to Array.Reverse: the reference to the array you want to reverse. In this example, an integer array is used.
Int Array
Then Array.Reverse method is called twice. This reverses the original array, and then reverses the reversed array.
C# program that uses Array.Reverse method
using System; class Program { static void Main() { // Input array. int[] array = { 1, 2, 3 }; // Print. foreach (int value in array) { Console.WriteLine(value); } Console.WriteLine(); // Reverse. Array.Reverse(array); // Print. foreach (int value in array) { Console.WriteLine(value); } Console.WriteLine(); // Reverse again. Array.Reverse(array); // Print. foreach (int value in array) { Console.WriteLine(value); } } }

Usage notes. Array.Reverse is easier to use than a custom reversal algorithm. Not only does Array.Reverse use optimized logic, but it also makes your program simpler. It is an improvement.
A summary. Here we examined the Array.Reverse static method. This method receives an Array type parameter, such as an int array, and reverses the order of the elements in that same array.
