Study Notes
Classes and Objects in C#
- An object in C# represents an instance of a class, which is a blueprint for creating objects.
- A class defines a custom data type that includes data (fields) and behavior (methods).
Defining Classes in C#
- The
classkeyword is used to define a class in C#.
Class Members
- A field in a C# class is a variable that is part of the class.
- Fields typically have a private access modifier and are accessed through properties.
- Properties are used to encapsulate fields and provide a way to get or set their values.
Properties
- The
setaccessor in a property is used to assign a value to the underlying field. - In C# 3.0 and later, auto-implemented properties can be used if no additional logic is needed in the getter or setter.
Methods
- A method in C# is a block of code that can be called multiple times from different parts of a program.
- A method may or may not return a value.
Constructors
- A constructor in C# is a special method that is called when an object is created.
- A constructor is defined with the same name as the class and is used to initialize objects.
Creating Objects
- Objects of a class are created in C# using the
newkeyword, followed by the class name and any required parameters.
