I'm working on a C# Windows Application which has a Web Service. I'd like to know how to communicate with the Web Service using XML. To be precise, I have a data set that has to go to the Database via Web Service. So I'd want to send this data using XML to the Web Service. How would I do that please?


How much do you know about Web Services now?
If you are building the WS, you can design the interface to take the types of data you want.
If you are just consuming the WS, you will need to adhere to the interface provided to you.
If you are using Visual Studio, it's pretty easy to bind to the web service and make calls.

You start with Project->Add Service Reference->Advanced->Add Web Reference
