推荐答案

看看下面类似的问答"讨论. 接口/基类中的C#枚举? 如何在其中创建抽象枚举NET类库? Have a look at similar Question-Answer discussions below. C# enum in interface/base class? How can I make an abstract enum in a .NET class library?

接口只能包含方法，委托，事件或索引器的签名.您不能在接口中声明枚举或任何其他类型-您必须在接口外部进行声明.恐怕这就是语言定义！ MDSN接口 [ ^ ] An interface can only contain the signatures of methods, delegates, events or indexers. You cannot declare an enum or any other type in an interface - you have to make the declaration outside the interface. That is the language definition I''m afraid! MDSN interface[^]

您应该将枚举放在界面之外. You should put your enum outside the interface. interface IUserControlFactory { } enum MyEnum { }
