无连接可以作出，因为目标机器积极地拒绝它127.0.0.1 [英] No connection could be made because the target machine actively refused it 127.0.0.1

问题描述

我尝试连接到主机使用WebRequest类在不同的服务器上的Web服务。 Web服务将返回一个字符串作为回应。这样做虽然我得到一个错误：

System.Net.Sockets.SocketException：无连接可以作出
，因为目标机器积极拒绝，

解决方案

后6天我找到了答案这让我疯狂的答案是在Web配置文件

禁用代理

I try to connect to a web service hosted on a different server using the WebRequest Class. The web service returns a string as a Response. While doing so I get an Error:

"System.Net.Sockets.SocketException: No connection could be made because the target machine actively refused it"

System.Net.WebException: Unable to connect to the remote server ---> System.Net.Sockets.SocketException: No connection could be made because the target machine actively refused it 127.0.0.1:14012 at System.Net.Sockets.Socket.DoConnect(EndPoint endPointSnapshot, SocketAddress socketAddress) at System.Net.ServicePoint.ConnectSocketInternal(Boolean connectFailure, Socket s4, Socket s6, Socket& socket, IPAddress& address, ConnectSocketState state, IAsyncResult asyncResult, Exception& exception) --- End of inner exception stack trace --- at System.Net.HttpWebRequest.GetRequestStream(TransportContext& context) at System.Net.HttpWebRequest.GetRequestStream() at Limoallover.InsertSoapEnvelopeIntoWebRequestUS(XmlDocument soapEnvelopeXml, HttpWebRequest webRequest) at Limoallover.dawUpdateDriverStatus(String apiId, String apiKey, String idTrip, String tripCode, String statusCode) at Limoallover.UpdateJobStatus(String Lat, String Lng, Int32 DriverID, Int32 nJobStatus, Int32 nJobId, String CompanyID, String idTrip, String tripCode, String statusCode)

    return webRequest;

    XmlDocument soapEnvelop = new XmlDocument();

解决方案

after six days i find the answer which make me crazy answer is disable proxy at web config file
