How do you write a C# Extension Method for a Generically Typed Class
Is it possible to declare extension methods for generic classes?
public class NeedsExtension<T> { public NeedsExtension<T> DoSomething(T obj) { // .... } } 14 Answers
To extend any class
public static class Extensions { public static T DoSomething<T>(this T obj) { //... } } To extend a specific generic class
public static NeedExtension<T> DoSomething<T>(this NeedExtension<T> obj) { //... } 1Yes, but you forgot the this keyword. Look at Queryable that provides all the LINQ operators on collections.
Sure
public static void SomeMethod<T>(this NeedsExtension<T> value) { ... } How do you write a C# Extension Method for a Generically Typed Class
public static class NeedsExtension<T> { public static string DoSomething <T>(this MyType<T> v) { return ""; } // OR public static void DoSomething <T>(this MyType<T> v) { //... } } 5
