Creating Web Service using ASP .NET

To know about basics of web service read this article.

1.   Create an ASP .NET web service application using Microsoft Visual Studio.

2. Take a scenario that we have to convert Celsius to Fahrenheit and vice versa.
3.   Below is the code for our scenario:

using System;
using System.Web;
using System.Web.Services;
using System.Web.Services.Protocols;

[WebService(Namespace = "http://ConversionWebService.org/Temp")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
public class Service : System.Web.Services.WebService
{
    public Service () {

        //Uncomment the following line if using designed components 
        //InitializeComponent(); 
    }
    [WebMethod(Description = "Convert Celsius to Fahreinheit")]
    public double ToFahreinheit(double C)
    {
        return C * (9.0/5.0) + 32;        
    }

    [WebMethod(Description = "Convert Fahreinheit to Celsius")]
    public double ToCelsius(double F)
    {
        return (F - 32) * (5.0/9.0);        
    }
   }

4. Build and run the web service, you will see the following output:

5.Now, we will test the web service by giving input values and invoke it.Below are the screen shots which will show the input given and the results:
