Windows Phone - 找不到XmlDocument

Question

在我的Windows手机应用程序中，我需要使用XmlDocument类。但我仍然会遇到错误

Error 1 The type or namespace name 'XmlDocument' could not be found (are you missing a using directive or an assembly reference?)

我添加了参考和using System.Xml

但它没有帮助。

这是我的SOAP示例代码，我需要修改它以使用XDocument Edit - 添加SOAP示例代码

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 soapEnvelop = new XmlDocument();
        soapEnvelop.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 soapEnvelop;
    }

    private static void InsertSoapEnvelopeIntoWebRequest(XmlDocument soapEnvelopeXml, HttpWebRequest webRequest)
    {
        using (Stream stream = webRequest.GetRequestStream())
        {
            soapEnvelopeXml.Save(stream);
        }
    }`
