我们将一些 Web 服务从 asmx 升级到 WCF，我需要更改应用程序中对 Web 服务的调用，合同名称和方法名称和签名相同。从调用 asmx Web 服务到 svc Web 服务（WCF）有什么简单的方法吗？

     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;
    }

我试图更改 .config 文件中的 Web 服务地址，但它给了我错误：

(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 方法中我改变了：

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

至

 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 WCF 服务，不胜感激。

谢谢。

你使用的绑定是什么？确保它是 BasicHttpBinding - 那么您可能不必更改客户端中的任何内容
