PublisherChapter 4. Web Services
The primary purpose of ASP.NET web
services is to provide access to application functionality through
standard web protocols (including HTTP and XML), regardless of the
application's location or the platform on which it
is built. When your application exposes functionality as a web
service, that functionality can be consumed by clients on any
platform, presuming the clients understand XML and SOAP and can
communicate via the HTTP protocol. More plainly, a web service is a
function that is called over the Internet.An ASP.NET web service can be very simple or it can provide complex
functionality. It can return a variety of data typesfrom
simple strings and integer values to complex data types such as
classes and datasets. Web services are traditionally thought of as
providing only business services (e.g., you call a method, perhaps
passing in some parameters, and you receive a return value), but
there's no reason why you can't
create a web service that returns a chunk of HTML. Doing so would
allow you to provide cross-platform access to functionality similar
to that provided by ASP.NET Server Controls, albeit with some
performance overhead.
