安装后每当我运行Windows服务时，程序都会响应并显示一条错误消息.它会说它什么也不能运行.代码如下:
Whenever I run a windows service after installation, the program will respond with a error message. It will says it has nothing to run. The code is below :

推荐答案
所有工作都是在OnStart中执行和完成的，因此不需要将其作为服务.对于服务OnStart，应该启动一个执行定期工作的后台线程，但是此处的操作看起来像是一次完成的事情.如果OnStart实际上没有启动任何内容，则服务管理器将产生您所看到的消息.
此外，服务与用户之间没有交互，因此Console.ReadKey和Console.WriteLine不会很有帮助.

OnStart不应该做任何工作，它要做的就是启动一个后台线程.线程的目的是运行并继续工作，直到调用OnStop方法为止.调用OnStop时，线程应退出，以便服务可以关闭.

Windows服务不是Windows启动时运行的程序.服务是需要从Windows启动，在后台运行并在Windows关闭时关闭的应用程序.
如果您只需要Windows启动时运行一次的应用程序，则不需要服务.您只需要一个从适当位置链接到的普通应用程序(控制台或GUI，没关系).
有几种方法可以使您的应用在启动时运行，我知道的两种最典型的方法是编辑 ^ ]或在用户启动"文件夹中为您的应用添加快捷方式.
如果您的应用程序需要半周期运行(例如每6或12个小时运行一次)，则Windows有一个任务计划程序，可以在需要时启动该应用程序.

All of the work is performed and completed inOnStartso there''s no need for this to be a service. For a serviceOnStartshould kick off a background thread that does periodic work but the actions here look like a once and done thing. IfOnStartdoesn''t actually start anything then the service manager will produce the message you''re seeing.
Also, services have no interaction with the user soConsole.ReadKeyandConsole.WriteLinewon''t be very helpful.
[COMMENT RESPONSE]
OnStart should not do any work, all it should do is start a background thread. The purpose of the thread is to run and keep doing work until the OnStop method is called. When OnStop is called the thread should exit so the service can close.

Windows Services aren''t programs that run when Windows starts. Services are applications that need to start with windows, run in the background and close when Windows shuts down.
If all you need is an app that runs once when Windows starts, then you don''t need a Service. All you need is a normal application (Console or GUI, it doesn''t matter) that is linked to from the proper place.
There are several ways to make your app run on startup, the two most typical that I know of are to edit the registry[^] or to put a shortcut to your app in the users "Startup" folder.
If your app needs to run semi-periodically, say every 6 or 12 hours, then Windows has a Task Scheduler that can launch an app when it needs it.

获取新答案的时间.您现在有一个完全不同的问题，该问题将导致需要发布新帖子，注释系统当然不是为代码转储而构建的.
无论如何，这是调试服务的一种快速而肮脏的方法:在Visual Studio .NET下调试Windows服务 [ ^ ]
这应该可以帮助您找到异常并插入适当的边界检查代码.
Time for a new answer. You now have an entirely different question which would have warranted a new post, the commenting system certainly wasn''t built for code dumps.
Regardless, here''s the quick and dirty way to debug a service: Debugging Windows Services under Visual Studio .NET[^]
That should help you find the exception and insert appropriate bounds checking code.
