Message in Chinese (Simplified) (中文(简体))
名称为“<var>X</var>”、命名空间为“<var>namespace</var>”的 DataContract 无法添加到 DataContractSet，因为已经存在另一个与其具有相同数据协定名称的协定并且这些协定并不是等效的。
Unlocalized message
DataContract with name '<var>X</var>' and namespace '<var>namespace</var>' cannot be added to DataContractSet since another contract with the same data contract name is already present and the contracts are not equivalent.
