What parts does a C# class usually contain?

The class contains members. There are many different kinds of members but the three most important kinds are properties, methods and constructors.

• Properties allow you to read/write data values from/to an object that is created based on the class. Properties serve as a middleman between the external code and object underlying data values.
• Methods contain code blocks that can be executed on a class or on an object that is created based on the class.
• Constructors are special methods that are executed immediately after the object is created from class. A constuctor that is calles initializes the values of the object. A constructor is a method whose name is the same as the name of its class.
