public string InitialStateName { get; set; }

[<System.Workflow.ComponentModel.Compiler.ValidationOption(System.Workflow.ComponentModel.Compiler.ValidationOption.Optional)>]
member this.InitialStateName : string with get, set

Public Property InitialStateName As String

属性值

String

在创建状态机的实例时，StateActivity 所处的 StateMachineWorkflowActivity。

属性

注解

InitialStateName 属性是强制的，并且必须在创建 StateMachineWorkflowActivity 时提供。 状态机的 InitialStateName 类似于状态机中包含的任何其他状态活动。 状态活动可以是 StateMachineWorkflowActivity 根活动的直接子活动，一个 StateMachineWorkflowActivity 只能有一个 InitialStateName。

有关 InitialStateName 和 CompletedStateName 的更多信息，请参见StateMachineWorkflowActivity。
