Swap two variables in one line using C#

To swap two variables in a single line using the Bitwise XOR Operator.

val1 = val1 ^ val2 ^ (val2 = val1);

Above, we have set the values −

int val1 = 30;
int val2 = 60;

The following is the example to swap both the variable in one line using C# −

Example

using System;

class Demo {

   public static void Main(String[] args) {
      int val1 = 30;
      int val2 = 60;

      Console.WriteLine("Values before swap");
      Console.WriteLine(val1);
      Console.WriteLine(val2);

      val1 = val1 ^ val2 ^ (val2 = val1);

      Console.WriteLine("Values after swap");
      Console.WriteLine(val1);
      Console.WriteLine(val2);
   }
}
