Define Class |C# Tutorial

The class is a user-defined data type which is a collection of data, and methods to manipulate and access that data. Classes are a reference type and store into a heap.

Class members

The data and function within a class are known as class members.

Data members



Data members are those members that contain the data for the class. (field or constant).

Member function

Member functions are those members that provide functionality for manipulating the data in the class. They include a method, properties, constructors, and operator and finalize.

Passing parameters to methods

The parameters can be passed into the method by reference or by value.

Call by reference

When a variable is passed by reference the called method gets the actual variable so any changes made to the variable inside the method persist where the method exit. To achieve it we use the keyword “ref”.

Call by value

When a variable is passed by value the called method gets the identical copy of the variable which means any changes made are a loss when the method exits.
