Summary: Learn about the ICollection interface, iterations, and generic collections, and learn more about the IList interface below.

3. C # 2.0 specification (Generics IV)

Summary: A generic method is a method that is related to a particular type. In addition to the general parameters, the generic method also names a set of type parameters that you need to provide when using the method. Generic methods can be declared in class, struct, or interface declarations, and they can themselves be generic or non-generic. If a generic method is declared in a generic type declaration, the method body can reference the type parameter of the method and the type parameter that contains the declaration.

4. Generics in C #

Summary: This article focuses on generics in C #, because generics have a very important place in C # and are critical for writing high-readability, high-performance code. When I see my team's code more than once to contain a large number of non-generic collections, implicit boxing and unpacking operations, I would advise them to complement the generic base
