Message in Chinese (Traditional) (中文（繁體）)
屬於物件索引鍵的一個屬性值和儲存於 ObjectContext 中的對應屬性值不相符。如果屬於索引鍵的屬性傳回不一致或不正確的值，或者對屬於索引鍵的屬性做過變更後，未呼叫 DetectChanges，則可能發生這種情況。
Unlocalized message
The value of a property that is part of an object's key does not match the corresponding property value stored in the ObjectContext. This can occur if properties that are part of the key return inconsistent or incorrect values or if DetectChanges is not called after changes are made to a property that is part of the key.
