存在的類型 EntityReference<TEntity> 被初始化。

參數

relationshipName
String

關係名稱。

targetRoleName
String

相關結尾的角色名稱。

例外狀況

InvalidOperationException

當所提供的 EntityReference<TEntity> 已經初始化時，

-或-

當關係經理已經連接到一個 ObjectContext。

-或-

當關係管理器已經包含與該名稱及目標角色的關係時，

備註

此 InitializeRelatedReference 方法初始化由無參數建構子建立的既有 EntityReference<TEntity> 物件。 EntityReference<TEntity>透過提供的關係名稱和目標角色名稱初始化。

此 InitializeRelatedReference 方法僅在解序列化期間使用。
