Blocking tor from my website

I have a website written in ASP.NET MVC (and that means, it runs on windows server), that i want to protect from tor users. I thought about setting up some rules on windows firewall to block tor incoming connections, or something like that. Does anyone have any advices maybe? I would be very grateful.

You can get a list of TOR exit nodes from https://check.torproject.org/cgi-bin/TorBulkExitList.py?ip=your.ip.add.ress where your.ip.add.ress is the IP address address of your server.

# This is a list of all Tor exit nodes that can contact your.ip.addr.ess on Port 80 #
# You can update this list by visiting https://check.torproject.org/cgi-bin/TorBulkExitList.py?ip=my.ip.addr.ess #

You should be able to convert that into something that you can use to block TOR.
