问题描述

这是什么意思把一个 DataMemberAttribute 接口成员吗？
这将如何影响派生类？

What does it mean to put a DataMemberAttribute on an interface member? How does this affect derived classes?

推荐答案

如下面的签名中显示的数据成员属性是不可继承

As shown in the following signature, the DataMember attribute is not inheritable

[AttributeUsageAttribute(AttributeTargets.Property|AttributeTargets.Field, Inherited = false, 
    AllowMultiple = false)]
public sealed class DataMemberAttribute : Attribute

因此，这让很少的意义来装饰接口成员具有这种属性你将有装饰的实现类与此属性过于成员。

Therefore, it makes very little sense to decorate interface members with this attribute as you will have to decorate the implementing classes' members with this attribute too.
