How to programmatically determine the type of encryption and level of encryption from a wireless network device from a Windows 2003 server

Now my team is working on a network project using a Windows C # application . I did not know how to programmatically determine the type of encryption and level of encryption from a wireless network device from a Windows 2003 server.

After searching, I got WMI (Windows Management Tool) to solve the problem. +

Please offer an example / link to search for encryption type and level of encryption from a wireless network device from a Windows 2003 server
