Since the generics added by. NET 2.0, the methods and methods for coding are greatly affected. Generics are not only applied to collections, but also have a huge impact on interfaces and extraction algorithms.
The generic class definition can be
In generics, constraints can accomplish two things for you and the user: 1. constraints can convert runtime errors to compilation errors; 2. the constraints clearly provide the functions that must be implemented by parameters of the instantiation
C # provides a new type of loop: foreach, which is closely related to the set interface in the. NET Framework. In the program, we should use foreach for loop first.
Let's take a look at the following code snippet:

Generally, we do not recommend implementing the icloneable interface for the type. If a type supports the icloneable interface, all derived classes of this type must implement it, and all member types of this type must also implement the icloneable
