}

我在第3行的GetResponseCallback（IAsyncResult asynchronousResult）中收到错误ie response =（HttpWebResponse）webRequest.EndGetResponse（asynchronousResult）;

如何解决这个问题请让我知道。没有得到如何摆脱这个问题

解决方案

The remote server returned an error Exception when iam getting the response from the webservice.

using System;

using System.Collections.Generic;
using System.Linq;
using System.Text;
using Microsoft.Phone.Tasks;
using System.Net;
using System.IO;
namespace LocationSample
{
class ServiceConnection
{
public string Url = "";
private string postXml;

public delegate void OnServerEndResponse(string response, int statusCode);
public event OnServerEndResponse OnEndResponse;

public ServiceConnection()
{
Url = "http://13.1.38.89/mdc/servics/gvice.asmx";

}

public void ServiceCall(string pxml)
{
postXml = pxml;
WebRequest request = WebRequest.Create(Url);
request.Method = "POST";
request.ContentType = "text/xml;charset=UTF-8";

request.BeginGetRequestStream(new AsyncCallback(GetRequestStreamCallback), request);
}

void GetRequestStreamCallback(IAsyncResult asynchronousResult)
{
HttpWebRequest webRequest = (HttpWebRequest)asynchronousResult.AsyncState;
Stream postStream = webRequest.EndGetRequestStream(asynchronousResult);
string postData = postXml;
byte[] byteArray = Encoding.UTF8.GetBytes(postData);
postStream.Write(byteArray, 0, byteArray.Length);
postStream.Close();
webRequest.BeginGetResponse(new AsyncCallback(GetResponseCallback), webRequest);
}

void GetResponseCallback(IAsyncResult asynchronousResult)
{

HttpWebRequest webRequest = (HttpWebRequest)asynchronousResult.AsyncState;
HttpWebResponse response;
response = (HttpWebResponse)webRequest.EndGetResponse(asynchronousResult);
Stream streamResponse = response.GetResponseStream();
StreamReader streamReader = new StreamReader(streamResponse);
string Response = streamReader.ReadToEnd();
streamResponse.Close();
streamReader.Close();
response.Close();
OnEndResponse(Response, Convert.ToInt32(response.StatusCode));

}
}
}

public btnclik()

{

string id="123";

string pxml = @"<soapenv:Envelope xmlns:soapenv=""http://schemas.xmlsoap.org/soap/envelope/"" xmlns:web=""http://tempuri.org/"">" +
"<soapenv:Header/><soapenv:Body><web:RDevice>" +




"<web:PrimaryEmail>" + id + "</web:PrimaryEmail>" +
"</web:RDevice></soapenv:Body></soapenv:Envelope>";
ServiceConnection cs = new ServiceConnection();
cs.ServiceCall(pxml);
cs.OnEndResponse += new ServiceConnection.OnServerEndResponse(serviceConnection_OnEndResponse);

}

iam getting the error in GetResponseCallback(IAsyncResult asynchronousResult) at line 3 ie response = (HttpWebResponse)webRequest.EndGetResponse(asynchronousResult);

how to solve this problem please let me know.iam not getting how to came out of this problem
