C # Reading Notes (correct initialization sequence and rules of static constructor)

Correct initialization order

• Initialize all static Fields
• Call static Constructor
• Initialize all instance fields
• Call the instance Constructor

The exact sequence of static constructor calls cannot be determined, but it ensures that static constructor calls comply with the following rules:

• The static constructor is called before the first instance of the class is created.
• A static constructor can be called only once.
• The static constructor is called only after the static class members are initialized.
• The static constructor will be called before any static class member is referenced.
