Public Overridable Function AddForeignKey (property As IMutableProperty, principalKey As IMutableKey, principalEntityType As IMutableEntityType) As IMutableForeignKey

參數

property

IMutableProperty

外鍵定義所在的屬性。

principalKey

IMutableKey

參考的主要或替代索引鍵。

principalEntityType

IMutableEntityType

關聯性針對的實體型別。 這可能與關聯性以繼承階層中的衍生類型為目標時所定義的類型 principalKey 不同 (，因為索引鍵是在階層的基底類型上定義) 。
