Windows Workflow Foundation - 活动设计器 - 如何在运行时检查变量/参数？

Question

我正在使用WF4活动设计器调试工作流程。使用设计器进行调试，如何在运行时访问工作流实例状态以检查变量值？

例如，如何在以下屏幕中检查bool softwareFlashRequired的值：

非常感谢任何帮助！感谢。

我创建了一个CodeActivity，它接受变量，然后在其中有一个断点。您可以使用预处理器打开和关闭断点。例如：example.cpp /opt/compiler-explorer/windows/19.10.25017/lib/native/include/xmemory0(840): error C2280:

我把活动放到了工作流程之前。

为了便于在工作流程中使用，我将所有变量放在容器中，这样我的Debug CodeActivity只需要有一个InArgument，在断点处你可以看到所有变量的状态。
