Message in Chinese (Simplified) (中文(简体))
无法跟踪更改，因为自前面对具有同一属性名的同一更改跟踪器调用 EntityMemberChanging 或 EntityComplexMemberChanging 后，对象的状态已从“<var>X</var>”改为“<var>Y</var>”。有关正确报告更改的信息，请参阅 Entity Framework 文档。
Unlocalized message
The change cannot be tracked because the state of the object changed from '<var>X</var>' to '<var>Y</var>' since the previous call to EntityMemberChanging or EntityComplexMemberChanging on the same change tracker with the same property name. For information about properly reporting changes, see the Entity Framework documentation.
