Hi,I'm trying to do a parental control software project in C#. I made blocking and unblocking specific websites by using hosts file but the other part of my project is blocking the internet access. When I click a button, the internet access will be blocked and when another button is clicked the internet will be reachable. Block/enable internet access in C#, how can it be done? Thank you for your help.

One way is to disable/enable the network adapter(s). Here's a few posts to look at that should give you some idea: Click Here, Click Here Click Here

I'm not sure this is possible...imagine the problems that could be caused if this was possible...

As tinstaafl said, you can disable (or enable) an adapter using WMI (specifically the MSFT_NetAdapter class).
