Creating and calling web service with a namespace
Now add a web services
Now change the name space to the actual web address.
AddupService.cs
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Services;
/// <summary>
/// Summary description for AddupService
/// </summary>
[WebService(Namespace = "http://manas6/aspnet.35/WebServices2/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
// 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 AddupService : System.Web.Services.WebService {
public AddupService () {
//Uncomment the following line if using designed components
//InitializeComponent();
}
[WebMethod]
public int AddNumber(int n1, int n2)
{
return (n1 + n2);
}
}
Now if you run , the only name of the services will show up (unlike, when we used temp.uri ; Link) , and would be ready to take user's input.
Note the difference between two

Let us test the function
now add some numbers and click on invoke
Step : Calling this service from another location. Create a new website elsewhere in the net work or as a new application
http://manas6/aspnet.35/WebServices2Client/Default.aspx
Add a web reference ( using http://manas6/aspnet.35/WebServices2/AddupService.asmx?wsdl )
Watch the service is found and now add to your solution explorer, clicking add-reference
Now the the class and web method in the web service would be accessible to the client. Few years ago, webservice.htc allowed the developer to use JavaScript from an web page to consume the web services; but I found that it had been archived.
