Question

我的应用在某个设备上的某些时段崩溃，但无效的URI出现以下错误：指定的端口无效。

问题是我找不到具体的方法导致这个问题。它只在德国一些网络区域的1台设备上崩溃。堆栈跟踪仅显示以下消息：

Current domain_UnhandledException. Stack trace: System.UriFormatException: Invalid URI: Invalid port specified.
   at System.Uri.CreateThis(String uri, Boolean dontEscape, UriKind uriKind)
   at System.Uri..ctor(String uriString)

   at System.Threading._IOCompletionCallback.PerformIOCompletionCallback(UInt32 errorCode, UInt32 numBytes, NativeOverlapped* pOVERLAP)

我可以获得一些想法，我如何才能找到崩溃源？

从https://github.com/duplicati/httpserver/blob/master/HttpServer/HttpClientContext.cs

中找到新的详细信息

private void OnRequestLine(object sender, RequestLineEventArgs e)
        {
            _currentRequest.Method = e.HttpMethod;
            _currentRequest.HttpVersion = e.HttpVersion;
            _currentRequest.UriPath = e.UriPath;
            // Initialize _currentRequest.Uri to a synthesized path. This will be the final value if the host header is not sent
            string authority = _localEndPoint.Address.ToString();
            if (_localEndPoint.Port != 80) authority += ":" + _localEndPoint.Port;
            _currentRequest.Uri = new Uri((IsSecured ? "https://" : "http://") + authority + e.UriPath);
        }

无法捕获当前domain_UnhandledException System.UriFormatException的堆栈跟踪
