Question

我有：

[DataContract]
public class A 
{ 
    [DataMember]
    public int X { get; set; }
}

[DataContract]
[KnownType(typeof(Derived<A>))]
public class Base {}

[DataContract]
public class Derived<T>: Base { 

    [DataMember]
    public T Data {get; set; } 

}

Service方法返回包含Derived类对象的Base类的IEnumerable。自动生成的WCF客户端检索数据并正确检测类型并创建Derived类的实例，但Derived.Data.X未映射，即为0.收到的soap消息是正确的。有没有想法为什么派生类的泛型属性没有从客户端的soap消息中正确映射？

我强烈建议您避免服务合同中的泛型。 SOA世界与服务合同中的泛型类型不友好。请查看其他人报告的问题：

Error when updating service reference.The URI prefix is not recognized

WCF. Service generic methods

WCF generic property is not mapped in derived class

WCF泛型属性未在派生类中映射
