是否有可能覆盖或的shadow (的在C#中新)实例方法与扩展方法?
Is it possible to override or shadow (new in C#) instance methods with extension methods?
推荐答案
没有。从 MSDN :
您可以使用扩展方法来扩展一个类或接口,而不是覆盖它们。具有相同名称和签名作为一个接口或类的方法的扩展方法将永远不会被调用。在编译时,扩展方法总是有较低的优先级比类型本身定义的实例方法。
You can use extension methods to extend a class or interface, but not to override them. An extension method with the same name and signature as an interface or class method will never be called. At compile time, extension methods always have lower priority than instance methods defined in the type itself.
