How can I execute a batch script in a windows service in C#?
提问by Frank Flannigan
I'm trying to execute a .bat script in a C# windows service but it doesn't seem to be working.
我正在尝试在 C# windows 服务中执行 .bat 脚本，但它似乎不起作用。
So the script I am trying to execute, startup.bat, in turn calls another script, call catalina.bat ..., which in turn executes start java ...
所以我试图执行的startup.bat脚本，反过来调用另一个脚本，call catalina.bat ...然后执行start java ...
I can execute startup.bat manually but I want to run it as a Windows service. When I try to do that in a C# windows service application, nothing seems to happen. My Windows service code looks like this:
我可以手动执行 startup.bat 但我想将它作为 Windows 服务运行。当我尝试在 C# windows 服务应用程序中执行此操作时，似乎没有任何反应。我的 Windows 服务代码如下所示：
public class MyService : ServiceBase
{
public static void Main(string[] args)
{
ServiceBase.Run(new MyService());
}
protected override void OnStart(string[] args)
{
base.OnStart(args);
this.RunScript(@"bin\startup.bat");
Thread.Sleep(1000);
}
protected override void OnStop()
{
base.OnStop();
this.RunScript(@"bin\shutdown.bat");
Thread.Sleep(1000);
}
private void RunScript(string processFileName)
{
var startInfo = new ProcessStartInfo
{
FileName = "cmd.exe",
Arguments = "/C " + Path.Combine(@"C:\server", processFileName),
CreateNoWindow = true,
ErrorDialog = false,
RedirectStandardError = true,
RedirectStandardOutput = true,
UseShellExecute = false,
WindowStyle = ProcessWindowStyle.Hidden
};
startInfo.EnvironmentVariables.Add("CATALINA_HOME", @"c:\server");
var process = new Process();
process.StartInfo = startInfo;
process.Start();
}
}
I don't understand why this doesn't execute. What am I doing wrong?
我不明白为什么这不执行。我究竟做错了什么？
And yes, you may notice I'm trying to launch Tomcat on Windows as a service with C#. Well I'm doing that because I haven't been able to use tomcat7.exe for various reasons but it's probably better to not ask why I'm doing such things. Whatever the reason is, what I'm doing here should also work, shouldn't it?
是的，您可能会注意到我正在尝试在 Windows 上启动 Tomcat 作为使用 C# 的服务。好吧，我这样做是因为由于各种原因我无法使用 tomcat7.exe，但最好不要问我为什么要这样做。不管是什么原因，我在这里所做的也应该有效，不是吗？
Update in response to Gabe's suggestion:
更新响应 Gabe 的建议：
If I set UseShellExecute = true I get an exception:
如果我设置 UseShellExecute = true 我得到一个异常：
System.InvalidOperationException: The Process object must have the UseShellExecute property set to false in order to redirect IO streams.
at System.Diagnostics.Process.StartWithShellExecuteEx(ProcessStartInfo startInfo)
at System.Diagnostics.Process.Start()
at MyService.RunScript(String processFileName)
So I set RedirectStandardError and RedirectStandardOutput to false, which yields this error:
因此，我将 RedirectStandardError 和 RedirectStandardOutput 设置为 false，从而产生此错误：
System.InvalidOperationException: The Process object must have the UseShellExecute property set to false in order to use environment variables.
at System.Diagnostics.Process.StartWithShellExecuteEx(ProcessStartInfo startInfo)
at System.Diagnostics.Process.Start()
at MyService.RunScript(String processFileName)
argh! I feel exasperated!
啊！我觉得很气愤！

Run "cmd.exe" and pass "startup.bat" as an argument.
运行“cmd.exe”并将“startup.bat”作为参数传递。

Try setting "Allow service to interact with desktop" in your service setting.
尝试在您的服务设置中设置“允许服务与桌面交互”。

FileName = "%comspec%",
Arguments = "/C " + Path.Combine(@"C:\server", processFileName),

If your script runs fine as an interactive user but not as a service then there are a couple of obvious possible causes:
如果您的脚本作为交互式用户运行良好，但不能作为服务运行，那么有几个明显的可能原因：
- Your service is running under a user account that is unable to perform the actions in the script.
- Your script tries to interact with the desktop but can't because of session 0 isolation.
- 您的服务在无法执行脚本中操作的用户帐户下运行。
- 您的脚本尝试与桌面交互，但由于会话 0 隔离而无法进行。
These suggestions are essentially guesses but with so little information it's hard to do better.
这些建议基本上是猜测，但由于信息太少，很难做得更好。
