Question

我有类似这样的课程设置（我删除了很多其他属性，因为它们与我的问题无关......）：

public class Record : IRecord
{
    /// <summary>
    /// The type of recovery record and data needed to recover this record.
    /// </summary>
    [DataMember(Order = 1)]
    public IRecord Entry { get; private set; }

    [IgnoreDataMember]
    public object Entry
    {
        get { return Entry; }
    }
}

[ProtoContract
    , ProtoInclude(2, typeof(CaseRecord))
    , ProtoInclude(3, typeof(UserRecord))
]
public interface IRecord: IEntry
{
}

public interface IEntry
{
    long EntryId { get; set; }
    long DataSourceId { get; set; }
}

public class UserRecord : RecordEntry<UserRecord> 
{
    // ...other datamembers...

    [IgnoreDataMember]
    public override long EntryId { get; set; }
    [IgnoreDataMember]
    public override long DataSourceId { get; set; } 
}

[DataContract]
public abstract class RecordEntry<T> : RType<T>, IRecord
    where T : RType<T>, new()
{
    // other datamembers...
    public abstract long EntryId { get; set; }
    public abstract long DataSourceId { get; set; }
}

我（de）序列化记录流，如下：

Serializer.SerializeWithLengthPrefix(_stream, record, PrefixStyle.Base128);

Serializer.DeserializeWithLengthPrefix<Record>(_stream, PrefixStyle.Base128);

但是，当我尝试反序列化时，我的Record对象（类型为UserRecord）会返回EntryId和DataSourceId的值0和我{m}不完全确定为什么。我从[IgnoreDataMember]和Entry ID中删除了DataSource，但我仍然在保留时获得值0。正确填充对象的所有其他属性。

在[TestMethod] ...

中创建用户记录

userRecord1 = new UserRecord()
{
    // ...other datamembers
    EntryId = 123456789,
    DataSourceId = 123456789,
};

找到上述文章并将ProtoMember属性添加到EntryId和DataSourceId，我就能获得正确的值。

Protobuf（de）序列化
