C#

hello,
I want to start making a small application in C # (graphic mode).
The application must set parameters of the WLAN (Wireless PCI), for example:

- Configuring IP
- Configure DNS
- Set default gateway
- Set Channel
- Configuring WEP Encryption, WPA, WPA2.

I understand that I have to import some library.
All comments are welcome, so be very brief or code snippets.
Thank you all for reading my humble question.

PS Sorry for my poor pronunciation of English.
