webservice调用的两种方法

1。第一中不用说了。使用vs.net提供的工具，生成代理类。

2。使用webrequest的方法。

 

public   static  XmlDocument XmlSendByHttp( string  xmlString,  string  url,  string  SoapAction)         {             XmlDocument outxml  =   new  XmlDocument();             Stream oWriter  =   null ;              bool  bResult  =   true ;              byte [] data  =  Encoding.UTF8.GetBytes(xmlString);             HttpWebRequest myRequest  =  (HttpWebRequest)WebRequest.Create(url);             myRequest.Method  =   " POST " ;             myRequest.Headers.Add( " SOAPAction " , SoapAction);                 myRequest.Headers.Add( " ContentLength " , data.Length.ToString());             myRequest.ContentType  =   " text/xml; charset=utf-8 " ;              try             {                 oWriter  =  myRequest.GetRequestStream();                 oWriter.Write(data,  0 , data.Length);                 oWriter.Close();             }              catch             {                 oWriter.Close();                 bResult  =   false ;             }             Stream oReader  =   null ;              if  (bResult)             {                  try                 {                     HttpWebResponse oResponse  =  (HttpWebResponse)myRequest.GetResponse();                     oReader  =  oResponse.GetResponseStream();                     outxml.Load(oReader);                     oReader.Close();                 }                  catch                 {                 }             }              return  outxml;         }
