Set the service to restart after failure (double click the service in the control panel and have a look around on those tabs - I forget the name of it). Then, anytime you want the service to restart, just call <code>Environment.Exit(1)</code> (or any non-zero return) and the OS will restart it for you.

It would depend on why you want it to restart itself.

If you are just looking for a way to have the service clean itself out periodically then you could have a timer running in the service that periodically causes a purge routine.

If you are looking for a way to restart on failure - the service host itself can provide that ability when it is setup.

So why do you need to restart the server? What are you trying to achieve?

blocks|key|1711651|text|我不认为你可以在一个自包含的服务中(当你调用Restart时，它将停止服务，这将中断重新启动命令，并且它永远不会再次启动)。如果您可以添加第二个.exe+(一个使用ServiceManager类的控制台应用程序)，那么您就可以启动独立的.exe并让它重新启动服务，然后退出。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1711652|转念一想，您可能会让服务注册一个计划的任务(例如，使用命令行'at‘命令)来启动服务，然后让它自己停止；这可能会起作用。|1711653|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|F|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|G|8|@]|9|@]|A|$]]|$1|D|3|-4|5|6|7|H|8|@]|9|@]|A|$]]]|E|$]]

I don't think you can in a self-contained service (when you call Restart, it will stop the service, which will interrupt the Restart command, and it won't ever get started again). If you can add a second .exe (a Console app that uses the ServiceManager class), then you can kick off the standalone .exe and have it restart the service and then exit.

On second thought, you could probably have the service register a Scheduled Task (using the command-line 'at' command, for example) to start the service and then have it stop itself; that would probably work.

The problem with shelling out to a batch file or EXE is that a service may or may not have the permissions required to run the external app.

The cleanest way to do this that I have found is to use the OnStop() method, which is the entry point for the Service Control Manager. Then all your cleanup code will run, and you won't have any hanging sockets or other processes, assuming your stop code is doing its job. 

To do this you need to set a flag before you terminate that tells the OnStop method to exit with an error code; then the SCM knows that the service needs to be restarted. Without this flag you won't be able to stop the service manually from the SCM. This also assumes you have set up the service to restart on an error. 

Here's my stop code:

<pre><code>...

bool ABORT;

protected override void OnStop()
{
 Logger.log("Stopping service");
 WorkThreadRun = false;
 WorkThread.Join();
 Logger.stop();
 // if there was a problem, set an exit error code
 // so the service manager will restart this
 if(ABORT)Environment.Exit(1);
}
</code></pre>

If the service runs into a problem and needs to restart, I launch a thread that stops the service from the SCM. This allows the service to clean up after itself:

<pre><code>...

if(NeedToRestart)
{
 ABORT = true;
 new Thread(RestartThread).Start();
}

void RestartThread()
{
 ServiceController sc = new ServiceController(ServiceName);
 try
 {
 sc.Stop();
 }
 catch (Exception) { }
}
</code></pre>

blocks|key|1712040|text|我将使用Windows+Scheduler计划重新启动您的服务。问题是你不能重新启动自己，但你可以停止自己。(你基本上已经把你坐在上面的树枝锯掉了……如果你理解我的类比)，你需要一个单独的过程来为你做这件事。Windows调度程序是一个合适的调度程序。安排一个一次性任务来重新启动您的服务(即使是在服务本身内部)，以便立即执行。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1712041|否则，您将不得不创建一个“牧羊人”进程来为您完成此任务。|1712042|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|F|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|G|8|@]|9|@]|A|$]]|$1|D|3|-4|5|6|7|H|8|@]|9|@]|A|$]]]|E|$]]

I would use the Windows Scheduler to schedule a restart of your service. The problem is that you can't restart yourself, but you can stop yourself. (You've essentially sawed off the branch that you're sitting on... if you get my analogy) You need a separate process to do it for you. The Windows Scheduler is an appropriate one. Schedule a one-time task to restart your service (even from within the service itself) to execute immediately.

Otherwise, you'll have to create a "shepherding" process that does it for you.

blocks|key|1712162|text|对这个问题的第一个回答是最简单的解决方案："Environment.Exit(1)“我在Windows+Server2008+R2上使用它，它工作得很好。服务自行停止，操作系统等待1分钟，然后重新启动。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1712163|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

The first response to the question is the simplest solution: "Environment.Exit(1)" I am using this on Windows Server 2008 R2 and it works perfectly. The service stops itself, the O/S waits 1 minute, then restarts it.

blocks|key|1711714|text|我不认为它可以。当一个服务被“停止”时，它会被完全卸载。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1711715|好吧，好吧，我想总会有办法的。例如，您可以创建一个分离的进程来停止服务，然后重新启动它，然后退出。|1711716|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|F|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|G|8|@]|9|@]|A|$]]|$1|D|3|-4|5|6|7|H|8|@]|9|@]|A|$]]]|E|$]]

I don't think it can. When a service is "stopped", it gets totally unloaded.

Well, OK, there's always a way I suppose. For instance, you could create a detached process to stop the service, then restart it, then exit.

blocks|key|1712191|text|只是路过:我想我会添加一些额外的信息...|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1712192|你也可以抛出一个异常，这将自动关闭windows服务，自动重新启动选项就会生效。唯一的问题是，如果你的pc上有一个开发环境，那么JIT会尝试启动，你会得到一个提示，说debug+Y/N。说no，然后它就会关闭，然后正常重新启动。(在没有JIT的PC上，它完全可以工作)。我之所以这么做，是因为这个JIT是Win+7的新特性(它曾经在XP等平台上工作得很好)，而我正在试图找到一种禁用JIT的方法……我可能会尝试这里提到的Environment.Exit方法，看看它是如何工作的。|1712193|克里斯蒂安:英国布里斯托尔|1712194|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|H|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|I|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|J|8|@]|9|@]|A|$]]|$1|F|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|G|$]]

Just passing: and thought i would add some extra info...

you can also throw an exception, this will auto close the windows service, and the auto re-start options just kick in. the only issue with this is that if you have a dev enviroment on your pc then the JIT tries to kick in, and you will get a prompt saying debug Y/N. say no and then it will close, and then re-start properly. (on a PC with no JIT it just all works).
the reason im trolling, is this JIT is new to Win 7 (it used to work fine with XP etc) and im trying to find a way of disabling the JIT.... i may try the Environment.Exit method mentioned here see how that works too.

The better approach may be to utilize the NT Service as a wrapper for your application. When the NT Service is started, your application can start in an "idle" mode waiting for the command to start (or be configured to start automatically). 

Think of a car, when it's started it begins in an idle state, waiting for your command to go forward or reverse. This also allows for other benefits, such as better remote administration as you can choose how to expose your application.
