Generics allow you to write classes or methods that can be used with any data type.
Write the specification of a class or method and use substitution parameters of data types. When the compiler encounters a function call to a class's constructor or method, it generates code that handles the specific data type.
Generics is a technology that enriches your programs by −
It helps you maximize code reusability, type safety, and performance .
You can create generic collection classes. The .NET Framework class library includes several new generic collection classes in the System.Collections.Generic namespace. You can use these generic collection classes instead of the collection classes in the System.Collections namespace.
You can create your own generic interfaces, classes, methods, events, and delegates.
You can create a generic class that is restricted to methods that allow access to a specific data type.
You can get information about types used in generic data types at runtime through reflection.
The above is the detailed content of Generics in C#. For more information, please follow other related articles on the PHP Chinese website!
