StateMachineWorkflowInstance(WorkflowRuntime, Guid) コンストラクター

定義

StateMachineWorkflowInstance クラスの新しいインスタンスを初期化します。

public:
 StateMachineWorkflowInstance(System::Workflow::Runtime::WorkflowRuntime ^ runtime, Guid instanceId);
public StateMachineWorkflowInstance (System.Workflow.Runtime.WorkflowRuntime runtime, Guid instanceId);
new System.Workflow.Activities.StateMachineWorkflowInstance : System.Workflow.Runtime.WorkflowRuntime * Guid -> System.Workflow.Activities.StateMachineWorkflowInstance
Public Sub New (runtime As WorkflowRuntime, instanceId As Guid)

パラメーター

runtime
WorkflowRuntime

現在のワークフロー ランタイム。

instanceId
Guid

Guid のインスタンスを示す StateMachineWorkflowActivity

例外

runtime が null 参照 (Visual Basic の場合は Nothing) です。

or instanceId が空の Guid です。

次の例では、StateMachineWorkflowInstance オブジェクトの新しいインスタンスを作成する方法を示します。 この例は、注文処理ステート マシンの SDK サンプルです。 詳細については、「 ステート マシンの順序付けサンプル」を参照してください。
