What is the method implemented using recursion in C#?

In C#, a recursive method is when a method calls itself within its own code. Recursion is a commonly used programming technique, especially for solving problems with repetitive structures. By using recursion, complex logic can be implemented succinctly. In C#, to implement recursion, the method needs to call itself using its own name within the method. It is important to ensure there is a proper termination condition for the recursion, otherwise it may lead to infinite recursion and result in a stack overflow.
