StateMachineWorkflowInstance(WorkflowRuntime, Guid) 생성자

정의

네임스페이스:

System.Workflow.Activities

어셈블리:

System.Workflow.Activities.dll

StateMachineWorkflowInstance 클래스의 새 인스턴스를 초기화합니다.

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)

매개 변수

runtime

WorkflowRuntime

현재 워크플로 런타임입니다.

instanceId

Guid

Guid 인스턴스를 나타내는 StateMachineWorkflowActivity입니다.

예외

ArgumentNullException

runtime이 null 참조(Visual Basic의 경우 Nothing)인 경우

또는 instanceId가 빈 Guid인 경우

예제

다음 예제에서는 StateMachineWorkflowInstance 개체의 새 인스턴스를 만드는 방법을 보여 줍니다. 이 예제는 Ordering State Machine SDK 샘플에 포함되어 있습니다. 자세한 내용은 Ordering State Machine 샘플합니다.
