protobuf-net跳过基类中的成员(接口类型)
protobuf-net跳过基类中的成员(接口类型)
提问于 2020-07-14 10:33:23
我有一个Base类，它定义一个名为Member的IMember类型的成员。然后我有一个继承Base的Child类，并定义了一个名为Member2的新成员IMember。我序列化了Child类的一个实例，该实例保存在Base类型的变量中，期望所有的子成员和基成员都被序列化。除了来自Child的Member2是序列化的，在Base类中定义的具有相同类型的成员不是序列化的(或者至少在反序列化时，它的值是null )
我的类完全是这样的：
[ProtoContract]
[ProtoInclude(100, typeof(Member))]
public interface IMember {
[ProtoMember(1, IsRequired = true)]
int value { get; set; }
}
[ProtoContract()]
public class Member : IMember {
[ProtoMember(1, IsRequired = true)]
public int value { get; set; }
}
[ProtoContract()]
public class Base {
[ProtoMember(1, IsRequired = true)]
public virtual string Name { get; set; } = "Base";
[ProtoMember(2, IsRequired = true)]
public IMember MyMember { get; set; } = null;
}
[ProtoContract()]
public class Child : Base {
[ProtoMember(1, IsRequired = true)]
public override string Name { get; set; } = "Child";
[ProtoMember(2, IsRequired = true)]
public IMember MyMember2 { get; set; } = null;
}测试代码如下：
static void Main(string[] args) {
Base b = new Child() {
MyMember = new Member() { value = 10 },
MyMember2 = new Member() { value = 20 }
};
var stream = new MemoryStream();
Serializer.Serialize(stream, b);
var bytes = stream.ToArray();
stream = new MemoryStream(bytes);
var obj = Serializer.Deserialize<Child>(stream);
Console.ReadLine();
}反序列化的对象obj具有Member == null，而具有Member2 != null。为什么会这样呢？

基类缺少用于指定层次结构的ProtoInclude属性。
[ProtoContract()]
[ProtoInclude(100, typeof(Child))]
public class Base {
[ProtoMember(1, IsRequired = true)]
public virtual string Name { get; set; } = "Base";
[ProtoMember(2, IsRequired = true)]
public IMember MyMember { get; set; } = null;
