Calling of Static Constructor and Instance Constructor

Question

As I know Constructors of parent class is called first and then child Class.But why In Case of static Constructor It executes from derived Class first and then Child Class?

Answer 1

Static Constructors are always executed before the non-static constructor. Static constructor is called when class is accessed first time.

• Static Constructors

From MSDN Doc,

• A static constructor does not take access modifiers or have parameters.
• A static constructor is called automatically to initialize the class before the first instance is created or any static members are referenced.
• A static constructor cannot be called directly. The user has no control on when the static constructor is executed in the program.
• 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.
• Static constructors are also useful when creating wrapper classes for unmanaged code, when the constructor can call the LoadLibrary method.
• If a static constructor throws an exception, the runtime will not invoke it a second time, and the type will remain uninitialized for the lifetime of the application domain in which your program is running.
