Chapter 3. Creating Types in C#
In this chapter, we will delve into types and type members.
Classes
A class is the most common kind of reference type. The simplest possible class declaration is as follows:
class YourClassName { }
A more complex class optionally has the following:
Preceding the keyword | Attributes and class modifiers. The nonnested class
modifiers are |
Following | Generic type parameters, a base class, and interfaces |
Within the braces: | Class members (these are methods, properties, indexers, events, fields, constructors, operator functions, nested types, and a finalizer) |
This chapter covers all of these constructs except attributes,
operator functions, and the unsafe
keyword, which are instead covered in Chapter 4. The following sections will enumerate
each of the class members.
Fields
A field is a variable that is a member of a class or struct. For example:
class Octopus
{string name;
public int Age = 10;
}
Fields allow the following modifiers:
Static modifier |
|
Access modifiers |
|
Inheritance modifier |
|
Unsafe code modifier |
|
Read-only modifier |
|
Threading modifier |
|
The readonly modifier
The readonly
modifier
prevents a field from being modified after construction. A read-only
field can be assigned only in its declaration or within the
enclosing type’s constructor.
Field initialization
Field initialization is optional. An uninitialized field has a default ...
