TopShelf [Failure] Stop不能为空

Question

.Net框架v4.0。

安装服务失败；

Topshelf.HostFactory Information: 0 : Configuration Result:
[Success] Name ZipPack
[Success] Description 9 Angle Zip Refresh
[Success] ServiceName ZipPack
Topshelf.HostConfigurators.HostConfiguratorImpl Information: 0 : Topshelf v3.2.150.0, .NET Framework v4.0.30319.42000
Topshelf.HostFactory Error: 0 : An exception occurred creating the host, Topshelf.HostConfigurationException: The service was not properly configured: 
[Failure] Stop must not be null
   at Topshelf.Configurators.ValidateConfigurationResult.CompileResults(IEnumerable`1 results)
   at Topshelf.ServiceExtensions.<>c__DisplayClasse`1.<CreateServiceBuilderFactory>b__d(HostSettings x)
   at Topshelf.HostConfigurators.HostConfiguratorImpl.CreateHost()
   at Topshelf.HostFactory.New(Action`1 configureCallback)
Topshelf.HostFactory Error: 0 : The service terminated abnormally, Topshelf.HostConfigurationException: The service was not properly configured: 
[Failure] Stop must not be null
   at Topshelf.Configurators.ValidateConfigurationResult.CompileResults(IEnumerable`1 results)
   at Topshelf.ServiceExtensions.<>c__DisplayClasse`1.<CreateServiceBuilderFactory>b__d(HostSettings x)
   at Topshelf.HostConfigurators.HostConfiguratorImpl.CreateHost()
   at Topshelf.HostFactory.New(Action`1 configureCallback)
   at Topshelf.HostFactory.Run(Action`1 configureCallback)

Program.cs看起来是这样的；

public static class Program
{
    public static void Main(string[] args)
    {
        HostFactory.Run(x =>
        {
            x.Service<ZipPackService>(s =>
            {
                s.ConstructUsing(name => new ZipPackService(new ServiceRepository(new FileHelper())));
                s.WhenStarted((tc, hostControl) => tc.Start(hostControl));
                s.WhenStarted((tc, hostControl) => tc.Stop(hostControl));
            });
            x.RunAsLocalSystem();
            x.StartAutomaticallyDelayed();
            x.SetDescription("9 Angle Zip Refresh");
            x.SetDisplayName("ZipPack");
            x.SetServiceName("ZipPack");
        });
    }
}

这是一个正在转换为服务的命令行程序。遵循Main()中入口点的Top大陆架手册示例。已经尝试过搜索引擎，但它们只是从Git返回源以获取错误信息。该服务继承自ServiceControl。

在服务中，Start()方法被定义为；

    public bool Start(HostControl hostControl)
    {
        PollProcess();
        return true;
    }

PollProcess()使用windows事件触发器来检测添加到目录中的文件。

缺少什么配置？

您有两个whenStarted，而最后一个应该是whenStopped

即

 public static void Main(string[] args)
{
    HostFactory.Run(x =>
    {
        x.Service<ZipPackService>(s =>
        {
            s.ConstructUsing(name => new ZipPackService(new ServiceRepository(new FileHelper())));
            s.WhenStarted((tc, hostControl) => tc.Start(hostControl));
            s.WhenStopped((tc, hostControl) => tc.Stop(hostControl));
        });
        x.RunAsLocalSystem();
        x.StartAutomaticallyDelayed();
        x.SetDescription("9 Angle Zip Refresh");
        x.SetDisplayName("ZipPack");
        x.SetServiceName("ZipPack");
    });
}
