Message in Chinese (Simplified) (中文(简体))
不应为数据协定名称为“<var>X</var>:<var>Y</var>”的类型“<var>Type Name</var>”。请考虑使用 DataContractResolver，或将任何未知类型以静态方式添加到已知类型的列表。例如，可以使用 KnownTypeAttribute 特性，或者将未知类型添加到传递给 DataContractSerializer 的已知类型列表。
Unlocalized message
Type '<var>Type Name</var>' with data contract name '<var>X</var>:<var>Y</var>' is not expected. Consider using a DataContractResolver or add any types not known statically to the list of known types - for example, by using the KnownTypeAttribute attribute or by adding them to the list of known types passed to DataContractSerializer.
