私のwcfサービスで次のメソッドを呼び出しています....
ObservableCollection<PatientViewModel> Search(List<string> searchTerms, SearchNature nature, SearchMode mode, List<SearchField> fields)
次の例外が発生します…</p>
ProtoBuf.ProtoException, protobuf-net, Version=2.0.0.627, Culture=neutral, PublicKeyToken=75e2634e27c46854
Invalid wire-type; this usually means you have over-written a file without truncating or setting the length; see http://stackoverflow.com/q/2152978/23354
ProtoBuf.ProtoReader.ReadInt32()
proto_4(Object , ProtoReader )
ProtoBuf.ServiceModel.XmlProtoSerializer.ReadObject(XmlDictionaryReader reader, Boolean verifyObjectName)
System.ServiceModel.Dispatcher.DataContractSerializerOperationFormatter.PartInfo.ReadObject(XmlDictionaryReader reader, XmlObjectSerializer serializer)

System.ServiceModel.Dispatcher.DataContractSerializerOperationFormatter.DeserializeParameters(XmlDictionaryReader reader, PartInfo[] parts, Object[] parameters, Boolean isRequest)

注: 2 番目と 3 番目のパラメーターを削除した場合。その方法は…</p>
ObservableCollection<PatientViewModel> Search(List<string> searchTerms, List<SearchField> fields)
これはうまくいきます。
パラメータ フィールドは列挙リストであり、問題なく逆シリアル化されます。
単一の列挙値で上記の例外が発生するのはなぜですか?
前もって感謝します。
ご参考までに...
[DataContract]
public enum SearchNature
{
[EnumMember] None,
[EnumMember] Letters,
[EnumMember] Numbers
}
[DataContract]
public enum SearchMode
{
[EnumMember] None,
[EnumMember] BeginsWith,
[EnumMember] Contains
}
[DataContract]
public enum SearchField
{
[EnumMember] None,
[EnumMember] FirstName,
[EnumMember] LastName,
[EnumMember] PatientId,
[EnumMember] PriorId,
[EnumMember] PhoneNumber,
[EnumMember] DateOfBirth
}
編集:
さらに、型が XmlProtoSerializer ではなく列挙型の場合に、ProtoOperationBehavior を変更して既定のシリアライザーを使用すると、サービス呼び出しは正常に機能します。
public override XmlObjectSerializer CreateSerializer(Type type, System.Xml.XmlDictionaryString name, System.Xml.XmlDictionaryString ns, IList<Type> knownTypes)
{
if (type.IsEnum) return base.CreateSerializer(type, name, ns, knownTypes);
if (model == null) throw new InvalidOperationException("No Model instance has been assigned to the ProtoOperationBehavior");
return XmlProtoSerializer.TryCreate(model, type) ?? base.CreateSerializer(type, name, ns, knownTypes);
}
