Is there a way to block Internet access to my PC by writing cod开发者_JS百科e in C#?
I'm using Windows 7, a way to control the firewall will also help. I've seen solutions for Windows XP and Windows Vista, but I didn't find any for '7'.
You can use the WMI class Win32_NetworkAdapter
to disable/enable the network adapter.
Here's a link to info about that class:

Edit: Due to comment said that you only want to disable incoming traffic.
If you want to disable only incoming traffic I think you might have to use the Windows Firewall API
, I've never used it so I'm not sure if it would be able to do that but seems plausible, and it is Win 7 compatible as far as I can tell.
Here's a link to it (I'd suggest the VBscript samples might be easier to translate to C# than the C++ samples):
