How to get smartcard reader name in Windows 7 using C# or C/C++?

Question

Hi! I'm trying to make a C# program which will use a C .dll (unfortunately, the .dll doesn't have good documentation) to access a smart card. One of the functions of the .dll uses name of the reader as argument. My problem is that I don't know how to get the name.

After looking for answers I found something similar to what I need in an example here: http://msdn.microsoft.com/en-us/library/aa379803%28VS.85%29.aspx I'm looking for a way to get szReader value as described in the aforementioned example using C#. Can anyone help me or at least point me in the right direction?

EDIT: Looks like nobody knows the answer so I'll expand the question: How do I get smartcard reader name using C/C++ and Windows API? I've read through MSDN site for smartcard API, but I couldn't find the function which will list readers. My idea is now to make a C/C++ .dll which will get in-between the smartcard .dll and C# program. It will produce list of readers, let user chose one and call the smartcard .dll using chosen name as argument.

Here's some info on the subject that seems useful, namely the name of SCardListReaders: http://pcsclite.alioth.debian.org/api/winscard_8h.html I'll try it out and report results.

Try looking up the WinSCard api usage on Pinvoke.net. Specifically SCardListReaders. Also, this is possibly a duplicate question 268899 which has a great example of ScardListReaders. Good luck!
