使实现枚举的类成为必需 [英] make necessitate a class for implement an enum

问题描述

大家好，

我需要使用于实现enum类型的类成为必需，该怎么办?
我也尝试了一个抽象类和interfac，但是它有错误

Hello everybody,

I need to make necessitate a class for implement an enum type, what should I do?
I also tried an abstract class and interfac, but its has error

    public abstract class AbstractUserControl
    {
// Error: The modifier 'abstract' is not valid for this item

        public abstract enum MyEnum
        {
            
        }
        public abstract UserControl GetUserControl();
        public abstract void Disposing();
    }

    interface IUserControlFactory
    {
//Error: 'MyEnum': interfaces cannot declare types
        enum MyEnum
        {
            
        }
    }

任何HLP都......

预先谢谢您.

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
{

}
