Web Service in ASP.NET

Sep 5 2013 5:08 AM

Sir, I want your help in the following subject.

1)I like to know what is meant by webservice?

2)which of the html function they normally represent?

Take a look to the following line:-

<%@ WebService Language="C#" CodeBehind="~/App_Code/Slideshow.cs" Class="Slideshow" %>

what is meant by CodeBehind?

What is the use of Class="Slideshow"?
