You'll need to fetch the data ("scrape" it) through something like a WebRequest
. That will give you the raw HTML or whatever it outputs.
I'm sure, without even looking, that it uses some kind of login as well, which you will have to support. I would guess that involves making a request with the credentials to some page and extract the cookie returned which you will have to pass around. The cookies are passed around as headers.
The first thing you'll have to do is examine the HTML returned and determine how to process it to get the information you want. I would use Chrome and it's excellent developer tools for this, or another browser like Opera or Firefox with similar capabilities. This will also work for figuring out how to handle the session cookie.
