How to Declare Method in C# Program

Method is the building block of object-oriented programming.

Methods are generally the block of codes or statements in a program that gives the user the ability to reuse the same code which ultimately saves the excessive use of memory, acts as a time saver and more importantly, it provides a better readability of code. 

It combines related code together and makes program easier. In C# method declaration, you can declare method by following way:


In the preceding example, the public is an access specifier,  void  is a return data type that return nothing and add() is a method name. There is no parameter define in add() method.

If the function returns integer value, then you can define function as follow:

If the function is returning string value, then you can define function as follow:

You must remember, whenever use return data type with method, must return value using return keyword from body. If you don’t want to return any value, then you can use void data type.
