In-depth exploration of C ++ static Constructor

The primary table is the address table of a class's virtual function. This table solves the inheritance and overload problems and ensures that it can reflect the actual function in a real way, this C ++ static constructor belongs to a class, rather than an instance. That is to say, this constructor will only be executed once. That is, it is automatically called by. NET before creating the first instance or referencing any static members.

Pay attention to the following points when using static constructors:

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 instance or any static member is referenced ,. NET will automatically call the static constructor to initialize the class. That is to say, we cannot directly call the static constructor, so we cannot control when to execute the static constructor.

3. A class can have only one C ++ static constructor.

4. A constructor without parameters can coexist with a C ++ static constructor. Although the parameter list is the same, one belongs to the class and the other belongs to the instance, so there is no conflict.

5. Run only once at most.

6. Static constructors cannot be inherited.

7. If the C ++ static constructor is not written and the class contains a static member with an initial value, the compiler automatically generates the default static constructor.
