How to send data from android app to asp.net web server using KSOAP

Revision 1
I want to send data from the android app to the web server my code is as follows

after link the Ksoap.jar lib to my android app java build path

package com.ahmed.soapvideoservice;

import org.ksoap2.SoapEnvelope;
import org.ksoap2.serialization.PropertyInfo;
import org.ksoap2.serialization.SoapObject;
import org.ksoap2.serialization.SoapPrimitive;
import org.ksoap2.serialization.SoapSerializationEnvelope;
import org.ksoap2.transport.AndroidHttpTransport;



import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;
import android.widget.TextView;

public class MainActivity extends Activity {
String NAMESPACE = "http://vladozver.org/";
String METHOD_NAME = "GetSumOfTwoInts";
String SOAP_ACTION = "http://vladozver.org/GetSumOfTwoInts";
String URL = "http://localhost:51305/Service1.asmx";
TextView tv;

@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
tv=(TextView)findViewById(R.id.textView1);
SoapObject Request = new SoapObject(NAMESPACE, METHOD_NAME);

PropertyInfo pi = new PropertyInfo();
pi.setName("Operand1");
pi.setValue(2);
pi.setType(int.class);
Request.addProperty(pi);

PropertyInfo pi2 = new PropertyInfo();
pi2.setName("Operand2");
pi2.setValue(5);
pi2.setType(int.class);
Request.addProperty(pi2);


SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
envelope.dotNet=true;
envelope.setOutputSoapObject(Request);

AndroidHttpTransport androidHttpTransport = new AndroidHttpTransport(URL);
try
{
androidHttpTransport.call(SOAP_ACTION, envelope);
SoapPrimitive result=(SoapPrimitive) envelope.getResponse();
tv.setText("result = "+result);
}
catch(Exception e)
{
e.printStackTrace();

}


}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.activity_main, menu);
return true;
}
}

and here is my asp.net web server

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Services;

namespace WebService1
{
    /// <summary>
    /// Summary description for Service1
    /// </summary>
    [WebService(Namespace = "http://vladozver.org/")]
    [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
    [System.ComponentModel.ToolboxItem(false)]
    // To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the following line.
    // [System.Web.Script.Services.ScriptService]
    public class Service1 : System.Web.Services.WebService
    {

        [WebMethod]
        public int GetSumOfTwoInts(int Operand1, int Operand2)
        {
            return Operand1 + Operand2;
        }

    }
}


I got an error in the android
