C# C windows服务在安装后不返回剪贴板数据

我有一个windows服务程序的代码，它应该时不时地清除剪贴板。在控制台应用程序中测试它证明它是一个工作代码，然后通过Topshelf nuget包将控制台应用程序转换为服务。但是，将其作为一项服务运行，它根本无法完成任务。在一些基本的日志记录之后，我发现剪贴板.Hastext和所有其他文件在安装了直接从调试文件夹安装的服务后返回false。我遗漏了什么，或者应该考虑的调试模式和部署模式之间的区别是什么

使用服务是不可能的

服务正在Windows会话0上的单独会话中运行。用户处于不同的会话中—始终为会话1、2等。服务无法从其他会话访问用户的剪贴板

相反，您可以创建要在用户会话中执行的Windows计划任务，该任务仅在用户登录任务时运行。时间表可能有任何重复间隔
