       Generic Class is a class whose instances can work on different types of data. Not only methods classes also can be created as generic classes.

Enumeration:

Static Class,Partial Class

Static Class:

Is a class whose members must be accessed without an instance of the class. 

In other words, the members of a static class must be accessed directly from (using the name of) the class, using the period operator

Is a class whose members must be created as static.

 In other words, you cannot add a non-static member to a static class: all members, except for constants, must be static
