Question

我在IIS 7.5及更高版本之上托管WCF服务使用protobuf-net绑定。

我与Guid类型属性签订了数据合同：


[Datacontract(Namespace = "http://lorem")]
public class MyCustomData {
  [DataMember(Order = 0)]
  public Guid Id { get; set; } // this ends up as empty, ie. 0000-0000-....
  [DataMember(Order = 1)]
  public int MyInt { get; set; } // serializes/deserializes ok
}

[ServiceContrac(Namespace = "http://ipsum"), Protobuf.ProtoContract]
public interface IMyService {
  ...
}

[ServiceBehavior(Namespace = "https://ipsum")]
public class MyService {
  public void ServiceMethod(MyCustomData data) {
    ...
  }
}

当呼叫到达服务时，问题是 MyCustomData.Id为空。

解决：

问题是由protobuf-net的“功能”引起的

订单0被protobuf-net（Does protobuf-net support [DataMember(Order=0)]?）丢弃：


[Datacontract(Namespace = "http://lorem")]
public class MyCustomData {

  [DataMember(Order = 0)]
  public int Dummy { get; set; } // had to define, otherwise I get invalid wire-type exception

  [DataMember(Order = 1)]
  public Guid Id { get; set; } // now ok

  [DataMember(Order = 2)]
  public int MyInt { get; set; } // serializes/deserializes ok
}

Protobuf-net无法反序列化Guid
