來自「子工作流程」的WorkflowInspectionServices.GetActivities

運行此代碼時出現錯誤。來自「子工作流程」的WorkflowInspectionServices.GetActivities

IEnumerable<Activity> activityList = WorkflowInspectionServices.GetActivities(activityCurrent); 


if (activityList.Count() <= 0)

我有許多工作流程，我想通過它的活動。我沒有問題，同時我在工作流中使用的活動是代碼活動或本地活動。問題來了，當我在工作流程中使用另一個工作流程（我希望我是有意義的）

錯誤是在activityList.Count()這是不能創建未知類型'{clr-namespace:....PhysicalInbound}目標'。

實際上，如果將「子工作流程」的內容放在「父級」工作流程中，它就可以工作。我猜它是與進口要做，但我一直沒能弄明白爲止：S
