C# Web Services problem

[longroad]

I need to create a web service with c# and asp.net

Im a little confused exactly how i should code this, whether i should
use a class file or if that would be unneccesary.

Its a web service that will calculate shipping costs for various states.
the 2 input parameters are state and weight (weight of the parcel).
I then need to return the shipping cost for the particular state in $.
Different states have different shipping costs, eg NSW and ACT is $12/kg
and theres 2 other rates for other states.

How would I go about firstly coding the web service, then the C# code in
the asp.net application?
The application will have a drop down list or radio buttons of various
states, which the user will pick one of. They will then enter the weight
into a textbox, click submit, and the weight should be calculated
corresponding to the state they entered.

I think this should be quite simple, however my C# skills aren't the
best, so I really do need some help.

Thanks in advance.

Re: C# Web Services problem

you should always code a web service irrelevent of the interface that will
access it - so start by finding some simple examples of web services in C#,
and get some method calls working. You can store your shipping rates in the
web.config file, or load them from a file (or db), and look them up at each
request to begin with concluding by loading into
HttpContext.Cur rent.Cache - or even hard code them if you need to do that.
the trick is to get your method call working using the default web service
interface before you ever consider creating a gui front end to actually
deliver the call.

As to working out the cost - you perhaps need some kind of hashtable to
store state and distance from shipping point, and calculate the weight per
mile for example, or perhaps base it on simple city zones - zone 3 for 25 K
is X. Shippings actually quite a complicated issue.
