What have you already tried? How did that work out? What research have you done before asking here?

I think there is a GMAIL API out there to interact with the mail box.

Hi,

The HTML Agility Pack (http://http://htmlagilitypack.codeplex.com/[^]) is a superb library for scraping web pages.

Once the page is loaded with the pack, you can use XPath queries to grab data - e.g.

\\a\@href

will get all the 'href' attributes of all link tags

\\div[@class='email']

will get the 'div' element that has the class name 'email'

\\div[@id='subject']\td

will get all immediate 'td' children of any div tags that have the id 'subject'.

As you can see being able to extract data from a web page this way is very straightforward - many other mechanisms will have you using nested loops or very complicated recursive functions.

Google HttpWebRequest. You can use that class to retrieve the source code of a web page, and then parse it. There are also several articles here on CodeProject that demonstrate the use of that class.
