Message in Chinese (Simplified) (中文(简体))
命名空间“<var>namespace</var>”中的类型“<var>Type Name</var>”无法用作数据协定类型的基类型，因为它本身不具有数据协定。请考虑使用 DataContractAttribute 特性标记类型“<var>Type Name</var>”。
Unlocalized message
Type '<var>Type Name</var>' in namespace '<var>namespace</var>' cannot be used as the base type of a data contract type, because it itself does not have a data contract. Consider marking type '<var>Type Name</var>' with the DataContractAttribute attribute.
