判斷給定 [serviceAction] 是否應該通告為可繫結至給定 [resourceInstance]。

參數
- operationContext
型別：System.Data.Services.DataServiceOperationContext
資料服務作業內容執行個體。
- serviceAction
型別：System.Data.Services.Providers.ServiceAction
要通告的服務動作。
- resourceInstance
型別：System.Object
服務動作所繫結之資源的執行個體。
- resourceInstanceInFeed
型別：System.Boolean
如果要序列化的資源執行個體位於摘要內，則為 true，否則為 false。true 的值表示序列化期間可能會多次呼叫這個方法，因為摘要內的每一個資源執行個體都會呼叫此方法一次。如果判斷是否要通告 [resourceInstance] 的服務動作是一個高成本的作業，提供者可能會選擇永遠都通告，好讓效能最佳化。
- actionToSerialize
型別：Microsoft.Data.OData.ODataAction%
要序列化的 ODataAction。伺服器會建構傳入此呼叫的版本，這可能會由這個介面的實作加以取代。這絕對不應該設定為 null，除非傳回 false。
傳回值
型別：System.Boolean
如果應該通告此服務動作，則為 true，否則為 false。
