Message in Chinese (Traditional) (中文(繁體))
無法將屬性 '<var>Property Name</var>' 的原始值設定為 null,因為實體型別 '<var>Type Name</var>' 上的 '<var>X</var>' 成員不可為 null。
Unlocalized message
The original value for the property '<var>Property Name</var>' cannot be set to null because the '<var>X</var>' member on the entity type '<var>Type Name</var>' is not nullable.
