从asmx切换到svc web服务

我们将一些web服务从asmx升级到了WCF，我需要在应用程序中更改对Web服务的调用，合约名称和方法名称和签名是相同的。有没有简单的方法可以从调用一个asmx Web服务到一个svc Web服务（WCF）？从asmx切换到svc web服务

 internal XmlDocument ServiceCall() 
    { 
     WebResponse reponseWeb = null; 
     string strReponse = string.Empty; 

     HttpWebRequest webRequest = this.CreateWebQuery(); 

     XmlDocument soapEnvelopeXml = this.CreerEnveloppeSoap(); 

     using (Stream stream = webRequest.GetRequestStream()) 
     { 
      soapEnvelopeXml.Save(stream); 
     } 

     XmlDocument xmlSoapRequest = new XmlDocument(); 

     try 
     { 
      reponseWeb = webRequest.GetResponse(); 
     } 
     catch (System.Exception ex) 
     { 
      throw ex; 
     } 

     Stream str = reponseWeb.GetResponseStream(); 
     StreamReader sr = new StreamReader(str); 

     xmlSoapRequest.Load(sr); 
     return xmlSoapRequest; 
    } 

    private HttpWebRequest CreateWebQuery() 
    { 
     HttpWebRequest webRequest = (HttpWebRequest)WebRequest.Create(this.UrlServiceWeb); 
     webRequest.Headers.Add("SOAPAction", "\"" + this.UrlHost + this.WCFNameContrat + "/" + this.MethodeWeb + "\""); 
     webRequest.ContentType = "application/soap+xml; charset=utf-8"; 
     webRequest.Accept = "text/xml"; 
     webRequest.Method = "POST"; 
     return webRequest; 
    } 

    private XmlDocument CreerEnveloppeSoap() 
    { 
     XmlDocument soapEnvelop = new XmlDocument(); 

     string appelMethode = "<" + this.MethodeWeb + " xmlns=" + "\"" + this.UrlHote + this.WCFNomContrat + "\"" + ">"; 

     string strParametres = string.Empty; 
     foreach (Parametre param in this.Parametres) 
     { 
      strParametres = strParametres + "<" + param.Nom + ">" + param.Valeur + "</" + param.Nom + ">"; 
     } 

     appelMethode = appelMethode + strParametres + "</" + this.MethodeWeb + ">"; 

     StringBuilder sb = new StringBuilder(_enveloppeSoap); 
     sb.Insert(sb.ToString().IndexOf("</soap12:Body>"), appelMethode); 

     // Get XML 
     soapEnvelop.LoadXml(sb.ToString()); 
     return soapEnvelop; 
    }

我试图在config文件来更改Web服务地址，它给我的错误：

(415) Cannot process the message because the content type 'application/soap+xml; charset=utf-8' was not the expected type 'text/xml; charset=utf-8'..

所以在CreateWebQuery方法我改变了：

webRequest.ContentType = "application/soap+xml; charset=utf-8"

到

webRequest.ContentType from "text/xml;charset=utf-8"

Web服务调用返回：

The remote server returned an error: (400) Bad Request.

我不熟悉的WCF服务，任何帮助表示赞赏。

谢谢。

什么是您使用的绑定？确保它是BasicHttpBinding - 那么你可能不需要改变任何东西在客户端
