Hi, I am new to c# language. Can someone please advice how can I go about writing XML data which has to confirm/validate with with a particular schema. So kind of schema aware programming.

I have the data and a schema. I need to write a xml document that will eventually validate with this schema.
Any code snippet or urls would be helpful.
Your inputs will be much appriciated.
Thanks,
