Nancyfx自托管无法阻止HttpListener

Question

我有一个应用程序,它具有基于NancyFx的休息服务,我发现它非常酷的框架.但是我有一个很大的问题就是阻止它.我的主机类看起来像这样:

public class RestHost : IStartStopAble
{
    private readonly string _uri;
    private readonly IWindsorContainer _container;
    private NancyHost _host;
    private Thread _wsThread;
    private WindsorBootstrapper _windsorBootstrapper;

    public RestHost(string uri, IWindsorContainer container)
    {
        _uri = uri;
        _container = container;
    }

    public void Start()
    {
        var uri = new Uri(_uri);

        _windsorBootstrapper = new WindsorBootstrapper(_container);
        _host = new NancyHost(uri, _windsorBootstrapper);

        _host.Start();
    }

    public void Stop()
    {
        _host.Dispose();
    }
}

如你所见,我和南茜一起使用windsor.一切都很好,我从主线程调用开始,停止和构造函数,但当我处置我的主机时,我抓住这个:

 HttpListener: HttpListenerException: The I/O operation has been aborted because of either a thread exit or an application request

例外.我找到了这篇论文:http://maykov.blogspot.ru/2009/02/c-httplistener-httplistenerexception-io.html但是我使用主线程并且不明白我怎样才能"保存"该线程,其中HttpListener创建了,我怎么能把它传递给南希.

我将非常感谢任何帮助,我甚至不知道,我在.Net框架的核心中如何处理HttpListener异常.

你可能还记得SynchronizationContext:

public void Start()
{
    // init _host ...

    _syncContext = SynchronizationContext.Current;
    _host.Start();
}

public void Stop()
{
    if (_syncContext == SynchronizationContext.Current)
    {
        _host.Dispose();
    }
    else
    {
        _syncContext.Post((state) =>
        {
            _host.Dispose();
        }
        , null);
    }
}
