How to create ASP.NET Web Services?

For creating of Web Services follow the following Steps:-

Step(1):- Open VS--->File-->New-->Project-->Select .Net Framework 3.5 version in drop down list-->Select Web in left hand side--> Select ASP.NET Web Service Application-->Give Name as you want-->Click on OK button.

Step(2):- When you click on OK button then you see following screen.

Step(3):- Now, we added new methods as our requirement as shown in below:-

  

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

namespace CalculatorWebServices
{
    /// <summary>
    /// Summary description for Service1
    /// </summary>
    [WebService(Namespace = "http://tempuri.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 string WebServiceDemo()
        {
            return "This is Calculator Web Services Demo By Santosh Kumar Singh";
        }

        [WebMethod]
        public int Addition(int a, int b)
        {
            return a + b;
        }

        [WebMethod]
        public int Subtration(int a, int b)
        {
            return a - b;
        }

        [WebMethod]
        public int Multiplication(int a, int b)
        {
            return a * b;
        }

        [WebMethod]
        public int Devision(int a, int b)
        {
            return a / b;
        }
    }
}

Step(4)Now, built the solution and run. After run we can see following image.

Step(4)When we click on Addition method we can seen 2 Textboxes and 1 Invoke button. Now we put values in both Text boxes and click on Invoke button then get output in xml format as shown in below.
