Rules of Static Constructor

Rules of Static Constructor

1. The static constructor for a class executes before any instance of the class is created.
2. The static constructor for a class executes before any of the static members for the class are referenced.
3. The static constructor for a class executes after the static field initializers (if any) for the class.
4. The static constructor for a class executes at most one time during a single program instantiation
5. A static constructor does not take access modifiers or have parameters.
6. A static constructor is called automatically to initialize the class before the first instance is created or any static members are referenced. 
7. A static constructor cannot be called directly.
8. The user has no control on when the static constructor is executed in the program. 
9. A typical use of static constructors is when the class is using a log file and the constructor is used to write entries to this file.

Syntax:

class ConstructorClass
