How to work with a Smart Card

My project I am working on a small program which has to set an alarm if the user locks the computer without removing the Smart Card from the computer.

I am using C# with WPF and .Net 4.0 and my smartcard is version V4.2C

My problem I have all the functionality to work but I simply don't know how to detect if the Smart Card is in the Smart Card Reader.

I have tried to search on google but with no result so I hope some of you can help me.

Solution

Well, if I google for "C# smartcard" the first link which pops up is a code project article. It appears that the project provides events for detection of smartcard insertion/removal which is probably what you want.
