我通常使用另一种方法来做同样的事情
using System.Xml;using System.Net;using System.IO;public static void CallWebService(){ var _url = "http://xxxxxxxxx/Service1.asmx"; var _action = "http://xxxxxxxx/Service1.asmx?op=HelloWorld"; Xmldocument soapEnvelopeXml = CreateSoapEnvelope(); HttpWebRequest webRequest = CreateWebRequest(_url, _action); InsertSoapEnvelopeIntoWebRequest(soapEnvelopeXml, webRequest); // begin async call to web request. IAsyncResult asyncResult = webRequest.BeginGetResponse(null, null); // suspend this thread until call is complete. You might want to // do something usefull here like update your UI. asyncResult.AsyncWaitHandle.WaitOne(); // get the response from the completed web request. string soapResult; using (WebResponse webResponse = webRequest.EndGetResponse(asyncResult)) { using (StreamReader rd = new StreamReader(webResponse.GetResponseStream())) { soapResult = rd.ReadToEnd(); } Console.Write(soapResult); }}private static HttpWebRequest CreateWebRequest(string url, string action){ HttpWebRequest webRequest = (HttpWebRequest)WebRequest.Create(url); webRequest.Headers.Add("SOAPAction", action); webRequest.ContentType = "text/xml;charset="utf-8""; webRequest.Accept = "text/xml"; webRequest.Method = "POST"; return webRequest;}private static Xmldocument CreateSoapEnvelope(){ Xmldocument soapEnvelopedocument = new Xmldocument(); soapEnvelopedocument.LoadXml( @"<SOAP-ENV:Envelope xmlns:SOAP-ENV=""http://schemas.xmlsoap.org/soap/envelope/"" xmlns:xsi=""http://www.w3.org/1999/XMLSchema-instance"" xmlns:xsd=""http://www.w3.org/1999/XMLSchema""> <SOAP-ENV:Body> <HelloWorld xmlns=""http://tempuri.org/"" SOAP-ENV:encodingStyle=""http://schemas.xmlsoap.org/soap/encoding/""> <int1 xsi:type=""xsd:integer"">12</int1> <int2 xsi:type=""xsd:integer"">32</int2> </HelloWorld> </SOAP-ENV:Body> </SOAP-ENV:Envelope>"); return soapEnvelopedocument;}private static void InsertSoapEnvelopeIntoWebRequest(Xmldocument soapEnvelopeXml, HttpWebRequest webRequest){ using (Stream stream = webRequest.GetRequestStream()) { soapEnvelopeXml.Save(stream); }}
