Csharp program for Shuffle the elements of array. Here more information.

// Include namespace system
using System;

public class Shuffling

	// of given location

	}
	// Returns the random location of array elements

				counter++;
			}
		}
	}
	// Function which is display array elements
	public static void display(int[] arr, int size)
	{

		{
			// Disply element value
			Console.Write("  " + arr[i].ToString());

		// Define array of integer elements
		int[] arr = {
			1 , 0 , -3 , 8 , 7 , 3 , 9 , 4 , 2 , 5 , 10 , 6
		};
		var size = arr.Length;
		// Before shuffling  array elements
		Console.WriteLine(" Initial array elements");
		Shuffling.display(arr, size);
		Console.WriteLine(" After Shuffle array elements");
		Shuffling.shuffleElement(arr, size);
		Shuffling.display(arr, size);
		Shuffling.shuffleElement(arr, size);

}

Output

 Initial array elements
  1  0  -3  8  7  3  9  4  2  5  10  6
 After Shuffle array elements
  1  6  8  -3  7  0  2  10  9  4  5  3
  3  8  7  9  6  0  2  4  5  1  10  -3
  5  8  1  4  9  6  -3  3  2  0  7  10
