我试图发送自定义命令的Windows服务。我的应用程序有一个窗口服务和一个窗体。当服务运行时，我想使用按钮单击事件在独立存储中创建一个文件。我正在使用本教程http://arcanecode.com/2007/05/30/windows-services-in-c-sending-commands-to-your-windows-service-part-7/。当我运行该程序并单击该按钮时似乎没有任何事情发生，并且该文件未放置到独立存储中。我已经在这些方法上设置了断点，以查看它们是否执行并且它们似乎有效。我不确定按钮点击方法是否可以从表单中的服务中获得隔离存储代码，但根据本教程我看不出问题会是什么。下面的源代码。发送命令到Windows服务

我已经回答了这个在您的其他线程，让我寻找任何新的信息在这里 –
给我你的项目adamt在微软，我会检查出来 –
