備註
此類別的執行個體用來代表升級與相關聯的工作定義。此類別被衍生自SPJobDefinition類別。SPUpgradeJobDefinition物件可以出現在SPTimerService物件相關聯的SPJobDefinitionCollection物件。
若要建立SPUpgradeJobDefinition類別的執行個體使用建構函式。藉由設定Object屬性指定升級的根物件。指定將Mode屬性設定為就地升級的模式。將它新增至工作佇列呼叫Add方法的適當工作定義集合。
當執行升級的計時器工作時，您可以使用此工作相關聯的SPUpgradeSession物件来監視進度。若要取得的物件識別碼， SessionId屬性來擷取SPUpgradeSession物件，然後呼叫 [ **GetObject()**以取得的物件。
