public delegate T MyGenericDelegate<T>(T arg); ``` ### 4.3 泛型协变与逆变 C# 4.0 引入了协变和逆变的概念,允许在某些情况下将泛型类型参数的使用放宽或限制。 ```csharp // 协变示例,out位置的T表明T可以被协变 public interface ICovariant<out T> { T Get(); } // 逆变示例,in位置的T表明...
Generic type names are provided after the class, structure, interface, or method name in angle brackets. This syntax tells the compiler that such a name is used in the definition. By convention, the type parameters use capital letters such asT,U, orTKey, andTValue. In effect, we delay th...
In C#, generic means not specific to a particular data type. C# allows you to define generic classes, interfaces, abstract classes, fields, methods, static methods, properties, events, delegates, and operators using the type parameter and without the specific data type. A type parameter is a ...

Generics in C# represent a cornerstone of modern software development, offering a powerful mechanism for creating reusable and type-safe code. This comprehensive article explores the fundamentals of generics, delving into practical examples and best prac
In this way a Generic provides code re-usability. publicstaticvoidSortList(){object[]iInputArray={3,5,8,6,10,6,2,1,12};iInputArray=Sort<int>(iInputArray);foreach(ObjectobjiniInputArray)Console.Write(" {0}",obj);object[]strInputArray={"A","C","T","R","E","D"};strInputArray=...
With Generics you can postpone setting parameter types to a function or class until that function or class has been instantiated by the client. So for example, let's say that we have a function that performs a generic operation on a set of parameters being passed in. ...
