Global constructor

Hi,
     I want to know that what the global constructor and in which scenario we used it ?

There's no such thing as a global constructor in C#.

It's possible for a class or struct to contain instance constructor(s) and/or a static constructor.

A static constructor initializes static data for the class or struct as a whole, is called at most once by the system and is guaranteed to run before any instance of that class or struct is created.

this one is not clear to me . but Thanks vulpes

Deepak, what do you mean by "global constructor"? Did you see the term used someplace? Or is there something you are trying to do that you need a global constructor?
