浅谈c#泛型的定义、继承、方法和约束（Definition, inheritance, method and restriction of c# generics） Definition, inheritance, method and restriction of C# generics Http:/// 2009-08-19 15:08 lpdg1818 hi.baidu, Id like to comment This article describes how to define a C# generic class, as well as the inheritance, methods, and constraints for implementing generic classes. C# generic parameterized types, the types as parameters abstracted, so that we can achieve better code reuse in practical application, and it provides a better type safety, higher efficiency, but in the constraints, it only supports the display of constraints, so it is not so good. In terms of flexibility. I think its more efficient because generics use the on-demand model when instantiated, that is, on-demand instantiation occurs at JIT (Just, In, Time) compile time. Heres how you can define a C# generic class. Its simple. You just need to be aware that the type has been parameterized here: Using System; Using System.Collections.Generic; Using System.Text; Namespace GenericTest { Class Program { Static void Main (string[] args) { The use of string / int to instantiate Test, T, S Test, string, int, t = new, Test, string, int (SHY520, 22); The generic class / / method call T.SetValue (); } } /**//// summary Just define a generic class, the class has two types of parameters, including T, S / / / / / / /summary Typeparam name= T / / / /typeparam type parameters Typeparam name= S / / / /typeparam type parameters Public, class, Test, T, S { / / the type parameters of a generic class can be used for class members Private T name; Private S age; Public Test (T, Name, S, Age) { T = Name; This.age = Age; } Public, void, SetValue () { Console.WriteLine (name.ToString ()); Console.WriteLine (age.ToString ()); } } } The above example is not appropriate. The purpose is to let beginner beginners understand the definition and instantiation methods of generics. As above, we define a generic class, so how do you implement the i
