问题 I have been using the following code for months (without problem) in a .NET 2.0/3.5 environment: string server="192.168.1.3"; IPHostEntry ipe = System.Net.Dns.GetHostEntry(server); IPAddress ipa = ipe.AddressList[0]; IPEndPoint ipep = new IPEndPoint(ipa, (int)UdpServices.Domain); Here, server is hardcoded to an IP address, but in my application it could potentially be something like "server.test.com". When converting my project to .NET 4.0, this code stopped working when directly passing an

问题 I'm running very simple signalr server self-hosted via Owin on ubuntu server 14.04, mono 3.2.8. (code below). Connecting/Disconnecting works fine on both a remote windows server and when I deploy the bits to the linux server. But when a client dies unexpectedly instead of telling signalr that he's disconnecting, that's when I get a never-ending SocketException only on the linux server only. The windows server disconnects the client after about 30 seconds or so, but the linux server spews the

问题 I define HttpClient in 2 different ways: 1. Plain vanilla: client = new DefaultHttpClient(); 2. Thread safe: DefaultHttpClient getThreadSafeHttpClient() { HttpParams params = new BasicHttpParams(); params .setParameter( "http.useragent", "Mozilla/5.0 (Linux; U; Android 1.1; en-us;dream) AppleWebKit/525.10+ (KHTML, like Gecko) Version/3.0.4 Mobile Safari/523.12.2"); HttpProtocolParams.setVersion(params, HttpVersion.HTTP_1_1); HttpProtocolParams.setContentCharset(params, "UTF-8"); final

问题 I have an android emulator I'm running from eclipse and just trying to connect to a simple socket server I wrote in .NET (c#). The server is running on the same machine on port 4505. I am able to telnet (through PuTTy) to the server and it works just fine, but when I try to connect to the server with the android emulator I get a: java.net.ConnectException - localhost/127.0.0.1:4505 - Connection refused at org.apache.harmony.luni.net error. I'm assuming this is because the emulator is on a

问题 I am trying to call a REST method from a handheld device (Windows CE / Compact framework) with this code: public static HttpWebRequest SendHTTPRequestNoCredentials(string uri, HttpMethods method, string data, string contentType) { ExceptionLoggingService.Instance.WriteLog("Reached fileXferREST.SendHTTPRequestNoCredentials"); WebRequest request = null; try { request = WebRequest.Create(uri); request.Method = Enum.ToObject(typeof(HttpMethods), method).ToString(); request.ContentType =

问题 Hi I am using Apache HTTP Client 4.0 to upload some files on a server based on HTTPS protocol. The uploaded application is running 24x7.
