How to swap two numbers in C#

In this article, we will discuss how to swap two numbers in C#.

• we can swap two numeric values with temporary variable
• we can also use XOR(^) operator
• we can swap two numeric values with simple arithmetics

With temporary variable:

var temp = first;
first = second;
second = temp;


With XOR

first = first ^ second;
second = second ^ first;
first = first ^ second;


And as following

first = first + second;
second = first - second;
first = first - second;
