Question

Do static variables have the same or similar functionality in C# as they do in C++?

Edit:

With C++ you can use static variables in many different contexts – such as: 1) Global variables, 2) Local function variables, 3) Class members – Would similar usages in C# behave similar to that of C++?

Answer 1

Static has multiple meanings in C++.

Static variables in C# basically only have a single meaning: variables scoped to a type. In C#, static on a type is used to denote a type-scoped variable. Static on a method is a type-scoped method. Static can also be used on a class to denote that the entire class is comprised only of static methods, properties, and fields.

There is no equivelent to static variables within a function scope, or non-class scoped static values.

Edit:

In reponse to your edit, C# basically only uses static for class members. Globals and local static function variables are not supported in C#. In addition, as I mentioned above, you can flag an entire class “static”, which basically just makes the compiler check that there are no non-static members in the class.
