Very Urgent

[sanjhay]

Is there any API in .Net to find whether the network cable is plugged / Unplugged?

Thanks in advance.

no there isnt,
you can use WMI to retrieve the IP address, if it fails that means the cable is not plugged in.

Hi Kovan,

I am really battling with this! Could you send me a code example please?

Much appreciated.

read this, good info

this should work, but its dirty and it requires WMI calls (which are slow most of the times, and the documentation is very very poor for WMI)

I will try to dig up how i implemented this, but i think mine was dirtier than anything, from what i vaguely remember, i would check IP address of a network connection, if it failed(threw exception) it was because network cable was not plugged, and if it was plugged it would either return nothing or the actual IP
