    static void Main()
    {
        int X = 10;
        int Y = 20;

        Console.WriteLine("Before swapping : X " + X + ", Y " + Y);
        Swap(ref X, ref Y);

        Console.WriteLine("After swapping  : X " + X + ", Y " + Y);
        Console.WriteLine();
    }
}

Output:

Before swapping : X 10, Y 20
After swapping  : X 20, Y 10

Explanation:

In the above program, we created a Sample class that contains two static methods Swap() and Main() method.

The Swap() method will interchange the values of parameters with each other, and in the Main() method, we created two local variables X and Y. Then swap the values using the Swap() method and print the swapped value on the console screen.
