I have been reading the book recently. I feel pretty good. Now I want to record some content as follows:

1. Static and non-static classes●. Static classes can only contain static members and
C # modifier: static
The Declaration belongs to the type owner rather than the Member of the object.
I. Non-static class
1. Non-static classes can contain static methods, fields, attributes, or events. Static class members belong to the class level
Chapter 5 define encapsulated class types
This chapter describes the object-oriented functions of c. First, we will introduce how to build a class type, then study the role of encapsulation, then discuss the definition of attributes, fields, and
A static constructor is used to initialize anyStatic data, or to perform a participates action that needs has med once only. It is called automatically before the first instance is created or any static members are referenced.

1. C # static Constructor
1. The static constructor neither has an access modifier nor a parameter. Because it is called by. NET, modifiers such as public and private are meaningless.2. When the first class
(1) It is used to initialize static and read-only fields.
(2) You cannot add access modifiers when adding static keywords because static constructors are private.
(3) Static constructor of a class can be executed at most once in a given application
the difference between static variable and ordinary variable
The description of the global variable (external variable) before being labeled static constitutes a static global variable. The global variable itself is the static storage mode, static
C # static usage,
I. Static class
The important difference between static classes and non-static classes is that static classes cannot be instantiated, that is, they cannot use the new keyword to create static class type variables. When declaring a
The type descriptor for a static variable is static. Static variables, of course, are static storage, but the amount of static storage is not necessarily static variables, such as external variables are static storage, but not necessarily static
C # static constructors and static members of generic classes [classic]
Is a static constructor always called at most once? Will static constructors be called? Take the following example:

1.1.1 Summary
In our day-to-day work, we often need to maintain a unique instance of the application. such as IO processing, database operations, and so on, because these objects occupy important system resources, so we have to limit the creation

Static constructors are a new feature of C # that seems to be rarely used. However, when we want to initialize some static variables, we need to use it. This constructor belongs to the class, not to where the instance belongs, which means that the
