- Learn how to create classes and instantiate objects that expose encapsulated field data by using class definitions, constructors, and the `new` operator.
After completing this module, you'll be able to:
Describe the .NET type system, the difference between value and reference types, and the benefit of using custom class types.
Explain the difference between a class and an instantiated object.
Create class definitions that include public data fields and constructors that accept zero or more arguments.
Create classes and instantiate objects that expose public field values.
- Learn how to implement read-write, read-only, and write-only class properties using property accessors and access modifiers, and how to implement methods and extension methods for a class.
After completing this module, you'll be able to:
Explain how the field, property, and method members of a class are used in the class definition and instantiated objects.
Implement class properties using 'get' and 'set' property accessors.
Create classes that use automatically implemented properties.
Create read-only and write-only properties using access modifiers for properties and property accessors.
Create class methods and overloaded methods that accept zero or more arguments using either 'value' or 'reference' types.
Create extension methods for a class.
Implement classes that use a combination of properties and methods to manage encapsulated data.
- Learn how to implement classes using advanced techniques like static classes, partial classes, and object initializers that can improve the readability, maintainability, and organization of your code.
After completing this module, you'll be able to:
Describe the differences between structured and object-oriented programs, the benefits of encapsulation, and the lifecycle of a class.
Restrict access to classes and members using private, static, and nested classes.
Improve code organization and maintainability using partial classes.
Improve code readability and maintainability using methods that implement named and optional arguments.
Improve code efficiency and readability using object initializers and copy constructors.
Explain the purpose of a class finalizer and the relationship between a finalizer and the garbage collector in .NET.
