Disconnect Network C#

Question

Is it possible for me to disconnect the systems connection to the internet without the need for detecting the network adapter etc.?

I would like to add this functionality to my software but can't find a proper method.

Can anyone shine some light on this.

I am running it through a WPF app.

Thanks

Have a look at this. No idea if it's what your lookng for: http://stackoverflow.com/questions/83756/how-to-programmatically-enable-disable-network-interfaces-windows-xp — Alastair Pitts, Sep 06 '10 at 23:15

There are many ways to implement your requirement, the best is depend on the platforms which you want support and for other requirements.

You can disable all Network cards.
You can temporary change the routing table.
You can use WFP (Windows Filtering Platform see http://msdn.microsoft.com/en-us/library/aa366510.aspx) to block connection of the level of firewall, but without direct usage of the firewall.

I am sure that it is not the full list of possible ways. I know no simple .NET API which can you use.

You should be careful to be sure that after the end of your application the computer can work as before.
