My webservice code is,

using System;
using System.Web;
using System.Web.Services;
using System.Web.Services.Protocols;
[WebService(Namespace = "")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
public class Service : System.Web.Services.WebService
    public Service () {
        //Uncomment the following line if using designed components
    public string HelloWorld() {
        return "Hello World";
    public int Addtion(int x, int y)
        return x + y;
and my application code is:

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;

namespace SimpleApplication
    public partial class Form1 : Form
        localhost.Service loc = new SimpleApplication.localhost.Service();
        public Form1()
        private void button1_Click(object sender, EventArgs e)
            int a, b, c;
            a = Convert .ToInt16 ( textBox1.Text);
            b = Convert.ToInt16 ( textBox2.Text);
            c = loc.Addtion(a, b);
            textBox3.Text = c.ToString();
            MessageBox.Show("" + c);

in REFERENCE.CS page i will get error like this "Could not establish connection to network"

[System.Web.Services.Protocols.SoapDocumentMethodAttribute("", RequestNamespace="", ResponseNamespace="", Use=System.Web.Services.Description.SoapBindingUse.Literal, ParameterStyle=System.Web.Services.Protocols.SoapParameterStyle.Wrapped)]
        public int Addtion(int x, int y) {
            object[] results = this.Invoke("Addtion", new object[] {
            return ((int)(results[0]));

You need to learn basics of web services first. is your webservice is running on localhost?
