Web services Xamarin表单-使用Visual studio 2012中编写的Web服务

我在VisualStudio2012中编写了一个简单的web服务

在InternetExplorer中测试web服务时，我得到以下结果

<?xml version="1.0" encoding="UTF-8"?>
<string xmlns="http://tempuri.org/">[{"ID":1,"ConsultantName":"Jim",
"ConsultantEmailAddress":"Jim@xyz.com","ConsultantCellNumber":null,
"ConsultantPhoneNumber":null},{"ID":2,"ConsultantName":"Steve","ConsultantEmailAddress":"Steve@xyz.com",
"ConsultantCellNumber":null,"ConsultantPhoneNumber":null}]</string>

用于创建隧道并访问本地主机，对于bar请求，请执行以下操作：

单击“开始按钮” 在搜索框中，输入“打开或关闭windows功能” 在功能窗口中，单击：“Internet信息服务” 单击：“万维网服务” 单击：“应用程序开发功能” 检查（启用）功能。除了CGI以外，我都查过了

我拿到表格了

我希望这对你有帮助：）

    private async Task ExecuteLoadConsultants ()
    {

        Initialized = true;
        IsBusy = true;

        ConsultantInfo x = new ConsultantInfo{ ConsultantName = "WEwewewewe" };
            Consultants.Add (x);

        // call to webservice 

            HttpWebRequest webRequest = 
                       (HttpWebRequest)WebRequest.Create ("http://10.0.2.2:53498/TennantMobileWS1.asmx?op=GetConsultantAll");
        webRequest.UseDefaultCredentials = true;
        webRequest.Method = "POST";
        webRequest.Accept = "application/json";
        webRequest.ContentType = "application/json";
        webRequest.UseDefaultCredentials = true;

        webRequest.BeginGetRequestStream(new AsyncCallback(GetRequestStreamCallback), webRequest);

        IsBusy = false;
    }



    private void GetRequestStreamCallback(IAsyncResult asynchronousResult)
    {

        HttpWebRequest request = (HttpWebRequest)asynchronousResult.AsyncState;
        // End the stream request operation

        Stream postStream = request.EndGetRequestStream(asynchronousResult);

        //Start the web request
        request.BeginGetResponse(new AsyncCallback(GetResponceStreamCallback), request);

    }

    void GetResponceStreamCallback(IAsyncResult callbackResult)
    {
        HttpWebRequest request = (HttpWebRequest)callbackResult.AsyncState;


        //  Remote server returned an error: (400) Bad Request on line below


        HttpWebResponse response = (HttpWebResponse)request.EndGetResponse(callbackResult);
        Stream streamResponse = response.GetResponseStream();
        StreamReader streamRead = new StreamReader(streamResponse);
        string responseString = streamRead.ReadToEnd();

    }
