WorkflowPersistenceService.UnlockWorkflowInstanceState(Activity) 方法

定義

命名空間:

System.Workflow.Runtime.Hosting

組件:

System.Workflow.Runtime.dll

在衍生類別中覆寫時，解除鎖定工作流程執行個體狀態。

protected public:
 abstract void UnlockWorkflowInstanceState(System::Workflow::ComponentModel::Activity ^ rootActivity);

protected internal abstract void UnlockWorkflowInstanceState (System.Workflow.ComponentModel.Activity rootActivity);

abstract member UnlockWorkflowInstanceState : System.Workflow.ComponentModel.Activity -> unit

Protected Friend MustOverride Sub UnlockWorkflowInstanceState (rootActivity As Activity)

參數

rootActivity

Activity

工作流程執行個體的根活動。

範例

下列範例示範 UnlockWorkflowInstanceState 方法的實作。 這個範例來自 FilePersistenceService.cs 檔案中的＜自訂持續性服務＞範例。 如需詳細資訊，請參閱 自訂持續性服務範例。

// Unlock the workflow instance state.
// Instance state locking is necessary when multiple runtimes share instance persistence store
protected override void UnlockWorkflowInstanceState(Activity state)
{
    //File locking is not supported in this sample
}

' unlock workflow instance state.  
' instance state locking is necessary when multiple runtimes share instance persistence store
Protected Overrides Sub UnlockWorkflowInstanceState(ByVal rootActivity As System.Workflow.ComponentModel.Activity)
    ' File locking is not supported in this sample
End Sub

備註

此方法是抽象的，所以它不包含有關鎖定與解除鎖定的預設實作。

實作自訂持續性服務時，如果想要實作鎖定配置，您將需要覆寫此方法，並且在以解除鎖定參數的值為基礎的 SaveWorkflowInstanceState 方法中提供鎖定-解除鎖定機制。
