解决方案

参见如何通过Window Service运行Window Application？ [ ^ ]

您无法从Windows服务显示表单，也无法从Windows服务运行GUI应用程序。原因是服务可以在没有用户登录的情况下运行。您应该做的是创建系统托盘应用程序（将其配置为在用户登录时运行），然后您可以让应用程序通知服务当它可用时，允许服务将通知推送给它。



我写了一篇文章，其中有一个Windows服务与系统托盘应用程序通信。它可能会或可能不会帮助您：



Synchronicity - 文件夹同步应用程序 [ ^ ]

伙计这是最高阶的线程坏死，但这根本不是真的。您可以通过收集用户的所有可用SessionID并使用wtsapi32.dll通过STAThread调度来编写是/否消息框

See How to run Window Application through Window Service?[^]

You can't show a form from a Windows Service, and you can't run a GUI application from a Windows Service. The reason is that a service can be running while no user is logged in. What you *should* do is create a system tray application (configure it to run when a user logs in), and then you can have the app notify the service when it's available, allowing the service to push notifications to it.

I wrote an article that has a windows service communicating with a system tray app. It may or may not help you:

Synchronicity - A Folder Synchronizing Application[^]

guys this is thread necromancy of the highest order, but this is simply NOT true. You can write yes /no messageboxes by collecting all available SessionID's of the users and dispatching using wtsapi32.dll via the STAThread
