我正在使用Quartz.net，并尝试让Quartz服务器在Windows服务中启动。我创建了一个Windows服务项目并包含了Quartz.net库。在我的Service类中，我有：
protected override void OnStart(string[] args)
{
try
{
Host host = HostFactory.New(x =>
{
x.Service<IQuartzServer>(s =>
{
s.SetServiceName("quartz.server");
s.ConstructUsing(builder =>
{
QuartzServer server = new QuartzServer();
server.Initialize();
return server;
});
s.WhenStarted(server => server.Start());
s.WhenPaused(server => server.Pause());
s.WhenContinued(server => server.Resume());
s.WhenStopped(server => server.Stop());
});
x.RunAsLocalService();
//x.RunAs(@"mydomain\mysusername", "mypassword");
x.SetDescription(Configuration.ServiceDescription);
x.SetDisplayName(Configuration.ServiceDisplayName);
x.SetServiceName(Configuration.ServiceName);
});
host.Run();
}
catch (Exception ex)
{
Log.Error(ex.Message);
Log.Error(ex.InnerException.Message);
}
}
我还创建了一个Windows服务安装程序，并使用以下命令在Visual Studio的命令提示符中成功安装了Windows服务:
installutil MyWindowsService.exe
当我在Windows服务列表中查看我的服务并尝试启动服务时，会弹出消息对话框：
The MyWindowsService service on Local Computer started and the
stopped. Some Services stop automatically if they are not in use by
other services or programs.
这里是我记录在事件查看器（log4net）中的输出：

有人知道我怎样才能让这个服务在不抛出错误的情况下启动吗？
提前感谢。
ex.InnerException.Message很容易导致空指针。请避免。 - mugume david
