Swapping two integers

Swapping Two Integers using different methods.
     1) Using Temporary variable
     2) Using Arithmetic Operators
     3) Using EX-OR operator

 Here is the complete source code.

	using System;
	namespace Swapping
	{
	class Swap
	{
	static void Main()
	{
	Console.WriteLine("Swapping Two Integers using different methods.\n");
	Console.WriteLine("Using Temporary variable.");
	Console.WriteLine("-----------------------------");
	int number1 = 10, number2 = 20;
	Console.WriteLine("Before Swapping \n");
	Console.WriteLine("number1 = " + number1);
	Console.WriteLine("number2 = " + number2);
	Console.WriteLine("\n");
	int temp;
	temp = number1;
	number1 = number2;
	number2 = temp;
	Console.WriteLine("After Swapping \n");
	Console.WriteLine("number1 = " + number1);
	Console.WriteLine("number2 = " + number2);
	Console.WriteLine("\n");
	Console.WriteLine("Using Arithmetic Operators.");
	Console.WriteLine("-----------------------------");
	number1 = 10; number2 = 20;
	Console.WriteLine("Before Swapping \n");
	Console.WriteLine("number1 = " + number1);
	Console.WriteLine("number2 = " + number2);
	Console.WriteLine("\n");
	number1 = number1 + number2;
	number2 = number1 - number2;
	number1 = number1 - number2;
	Console.WriteLine("After Swapping \n");
	Console.WriteLine("number1 = " + number1);
	Console.WriteLine("number2 = " + number2);
	Console.WriteLine("\n");
	Console.WriteLine("Using EX-OR operator");
	Console.WriteLine("-----------------------------");
	number1 = 10; number2 = 20;
	Console.WriteLine("Before Swapping \n");
	Console.WriteLine("number1 = " + number1);
	Console.WriteLine("number2 = " + number2);
	Console.WriteLine("\n");
	number1 = number1 ^ number2;
	number2 = number1 ^ number2;
	number1 = number1 ^ number2;
	Console.WriteLine("After Swapping \n");
	Console.WriteLine("number1 = " + number1);
	Console.WriteLine("number2 = " + number2);
	Console.ReadLine();
	}
	}
	}
