操作“<var>X</var>”(在命名空间为“<var>namespace</var>”的约定“<var>Contract Name</var>”中)将 http 正文格式指定为 JSON，但该操作的序列化机制不是 DataContract。只有 DataContract 序列化支持 JSON 格式。如果操作具有 XmlSerializerFormatAttribute，请考虑将其替换为 DataContractFormatAttribute。
Unlocalized message
Operation '<var>X</var>' (in contract '<var>Contract Name</var>' with namespace '<var>namespace</var>') specifies the http body format to be JSON but the serialization mechanism for the operation is not DataContract. JSON format is only supported with DataContract serialization. If you have an XmlSerializerFormatAttribute on the operation consider replacing it with DataContractFormatAttribute.
