如何实现定义另一个接口元素的接口

发布于 2024-12-22 04:26:20 字数 695 浏览 3 评论 0原文

Interface A
    {
      string x {get;set;}
      IEnumarable<InterfaceB> DetailList { get; set; }
    }
    Interface B
    {
     int z;
     int y;
    }

    Class B :Interface B
    {
      implements z;
      implements y;
    }
    Class A :Interface A
    {
      implements x;
      IEnumarable<ClassB> DetailList {get;set;} // This line is giving trouble.
    }

这段代码违反了OO概念吗？我想如果我从 InterfaceB 派生 ClassB 那么我可以在 ClassA 中使用 ClassB 而不是 InterfaceB。 VS不喜欢这个，它要求我在ClassA中使用InterfaceB而不是ClassB。还有其他方法可以做到这一点吗？

我愿意考虑替代设计选项，我有一些域对象，其属性由接口 A 定义，每个域对象都有由接口 B 定义的相应对象例如演唱会(A) 演唱会地点(B) 喜剧表演(A) 喜剧表演地点(B)

如果您认为我不够清楚，请随时提出更多问题。

原文

Interface A
    {
      string x {get;set;}
      IEnumarable<InterfaceB> DetailList { get; set; }
    }
    Interface B
    {
     int z;
     int y;
    }

    Class B :Interface B
    {
      implements z;
      implements y;
    }
    Class A :Interface A
    {
      implements x;
      IEnumarable<ClassB> DetailList {get;set;} // This line is giving trouble.
    }

Is this code violating OO concept. I thought if I derive ClassB from InterfaceB then I can use ClassB in my ClassA instead of InterfaceB. VS is not liking this, Its asking me to use InterfaceB instead of ClassB in ClassA.
Is there any other way to go about doing this.

I am willing to consider alternate designing options, I have some domain objects whose properties are defined by Interface A and each domain object would have corresponding object defined by interface B
e.g
concert(A) concertlocations(B)
comedyshow(A) comedyshowlocations(B)

Feel free to ask more questions if you think I am not being clear enough.
Thanks in Advance

你可以这样：

public interface InterfaceA<T> where T : InterfaceB
{
    string x {get;set;}
    IEnumerable<T> DetailList { get; set; }
}

public interface InterfaceB
{
    int z { get; }
    int y { get; }
}

public class ClassB : InterfaceB
{
    public int z { get; private set; }
    public int y { get; private set; }
}

public class ClassA : InterfaceA<ClassB>
{
    public int z { get; private set; }

    public string x { get; set; }

    public IEnumerable<ClassB> DetailList {get;set;} 
}

但我不确定这对你来说是否合适？

请参阅此处了解更多信息： c# 接口实现 - 为什么这不构建？

You can this:

public interface InterfaceA<T> where T : InterfaceB
{
    string x {get;set;}
    IEnumerable<T> DetailList { get; set; }
}

public interface InterfaceB
{
    int z { get; }
    int y { get; }
}

public class ClassB : InterfaceB
{
    public int z { get; private set; }
    public int y { get; private set; }
}

public class ClassA : InterfaceA<ClassB>
{
    public int z { get; private set; }

    public string x { get; set; }

    public IEnumerable<ClassB> DetailList {get;set;} 
}

but I'm not sure this is desirable for you?
