android - 使用 ksoap2 将参数传递给 .net Web 服务，始终传递 null(空)值

Question

我是 android 应用程序的新手，我正在使用 Ksoap2 访问 .Net webservice 并且调用在没有参数的情况下执行得很好。但是有了参数，我变得空了。我遵循了站点中提供的所有步骤。我尝试了一切可能但到目前为止没有运气。我希望有人可以帮忙，

 private static final String SOAP_ACTION = "http://www.agilelearning.com/GetProvincelist1"; 
 private static final String METHOD_NAME = "GetProvincelist1 "; 
 private static final String NAMESPACE = "http://www.agilelearning.com" ; 
 private static final String URL = "http://192.168.1.24/Service.asmx";



//Method executed when Province is selected
 private OnItemSelectedListener selectListener = new OnItemSelectedListener()
     {
         public void onItemSelected(AdapterView parent, View v, int position, long id)
         {
             try
             {
 ArrayList<String> districts=new ArrayList<String>();
                int Provinceid=position+1;//parent.getItemAtPosition(position).toString();          
                SoapObject request1 = new SoapObject(NAMESPACE, METHOD_NAME1);                              
                request1.addProperty("Provincename","East Province");
                SoapSerializationEnvelope envelope1 = new SoapSerializationEnvelope(SoapEnvelope.VER11); 
                envelope1.dotNet = true; 
                envelope1.setOutputSoapObject(request1); 
                HttpTransportSE at = new HttpTransportSE(URL); 
                at.debug = true;
                at.setXmlVersionTag("<?xml version=\"1.0\" encoding=\"UTF-8\"?>");
                at.call(SOAP_ACTION1, envelope1);               
                SoapObject rs = (SoapObject)envelope1.getResponse();                int count=rs.getPropertyCount();
                for(int i=0;i<count;i++)
                {
                    districts.add(rs.getProperty(i).toString());
                }
                ArrayAdapter<String> aa;         
                aa = new ArrayAdapter<String>(home1.this, android.R.layout.simple_spinner_item, districts); 
                aa.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
                sd.setAdapter(aa); 
             }
             catch(Exception ex)
             {
                 MessageBox("No Districts found");
             }

         }

我遇到了同样的问题。在我的例子中，我从 android 发送的参数名称与我的网络服务期望的参数名称不同。

它们必须相同。

    request.addProperty("DeviceId",uid); --add parameter from android


    [WebMethod]
    public LoginResult Login(string DeviceId) ---web service
    {
       .......
    }
