在Protobuf-net中装饰中间类

Question

在protobuf-net中，应该装饰哪个基类？这个类是直接子类还是最远的基类？或两者？

[ProtoContract] 
[ProtoInclude(42, typeof(Derived))] // Here? 
public abstract class BaseClass { } 

[ProtoContract] 
[ProtoInclude(42, typeof(Derived))] // Or Here? 
public abstract class Intermediary : BaseClass { } 

[ProtoContract] 
public class Derived : Intermediary { } 

Answer 1

每个预期子类型的直接父项，而不是始祖。

所以：BaseClass需要声明Intermediary，并Intermediary需要申报Derived：

[ProtoContract] 
[ProtoInclude(42, typeof(Intermediary))] 
public abstract class BaseClass { } 

[ProtoContract] 
[ProtoInclude(42, typeof(Derived))] 
public abstract class Intermediary : BaseClass { } 

[ProtoContract] 
public class Derived : Intermediary { }
