如何动态地向Protobuf-net格式化程序添加已知类型的列表？

DataContractSerializer

Protobuf

[ProtoInclude]

[DataContract]
public class Mydata
{
    [DataMember(Order = 1)]
    public int Saved
    {
        get;
        set;
    }
}

[DataContract]
public class Container
{
    [DataMember(Order = 1)]
    public object Data
    {
        get;
        set;
    }
}

DataContractSerializer

[TestMethod]
public void SerializeWithDataContractSerializer()
{
    var container = new Container()
    {
        Data = new Mydata()
        {
            Saved = 1
        }
    };
    DataContractSerializer serializer = new DataContractSerializer(typeof(Container), new[] { typeof(Mydata) });
    var ms = new MemoryStream();
    serializer.WriteObject(ms, container);
    ms.Position = 0;
    var containerSerialized = (Container)serializer.ReadObject(ms);
    Assert.AreEqual(((Mydata)container.Data).Saved, ((Mydata)containerSerialized.Data).Saved);
}

knownTypes

[TestMethod]
public void SerializeWithProtoBuf()
{
    var container = new Container()
    {
        Data = new Mydata()
        {
            Saved = 1
        }
    };

    var formatter = Serializer.CreateFormatter<Container>(new[] { typeof(Mydata) });
    var ms = new MemoryStream();
    formatter.Serialize(ms, container);
    ms.Position = 0;
    var containerSerialized = (Container)formatter.Deserialize(ms);
    Assert.AreEqual(((Mydata)container.Data).Saved, ((Mydata)containerSerialized.Data).Saved);
