我正在尝试将自定义命令发送到Windows服务。我的应用程序有一个Windows服务和一个表单。当服务运行时，我想使用按钮单击事件在隔离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/。当我运行程序并单击按钮时似乎没有发生任何事情，并且该文件未放入隔离存储。我已经在这些方法上设置了断点，看看它们是否已执行并且它们似乎有效。我不确定按钮单击方法是否可以从表单到达服务中的隔离存储代码，但根据本教程，我无法看到问题是什么。源代码如下。

答案 0 :(得分：0)
这里有几件事： 1.检查您的服务运行的帐户。使用服务安装程序，您可以指定。我使用System测试了完全方案（使用您的代码），以确保我可以访问我桌面上的文件作为日志测试，并且工作正常。 2.将测试用例限制为不记录到隔离，而是简单的文本文件日志。
我还发布了我用于你的其他帖子的代码 - 所以我们先把它清理一下然后找出要解决的问题。
