Hi Julien,
Try this. I copied it from MSDN somewhere but cannot recall now where from.
using
System;using
System.Net;using
System.Net.Security;using
System.Net.NetworkInformation;namespace
Examples.Net.AddressChanges{
public class NetworkingMonitor
{
public static void Networking( )
{
if (NetworkInterface.GetIsNetworkAvailable ( ) == true)
{
Console.WriteLine ( "Network Is Avalable" );
}
else
{
Console.WriteLine ( "Network Is NOT Avalable" );
}
NetworkChange.NetworkAddressChanged += new
NetworkAddressChangedEventHandler ( AddressChangedCallback );
}
static void AddressChangedCallback( object sender, EventArgs e )
{
NetworkInterface[] adapters = NetworkInterface.GetAllNetworkInterfaces ( );
foreach (NetworkInterface n in adapters)
{
Console.WriteLine ( "Name: {0} ID: {1}, Operational Status: {2}",
n.Name, n.Id, n.OperationalStatus );
}
}
} // NetworkingMonitor
}
You will see many methods in NetworkInterface, like this one (also from MSDN):
public static void DisplayMulticastAddresses( )
{
Console.WriteLine ( "Multicast Addresses" );
NetworkInterface[] adapters = NetworkInterface.GetAllNetworkInterfaces ( );
foreach (NetworkInterface adapter in adapters)
{
IPInterfaceProperties adapterProperties = adapter.GetIPProperties ( );
MulticastIPAddressInformationCollection multiCast = adapterProperties.MulticastAddresses;
if (multiCast.Count > 0)
{
Console.WriteLine ( adapter.Description );
foreach (IPAddressInformation multi in multiCast)
{
Console.WriteLine ( " Multicast Address ....................... : {0} {1} {2}",
multi.Address,
multi.IsTransient "Transient" : "",
multi.IsDnsEligible "DNS Eligible" : ""
);
}
Console.WriteLine ( );
}
}
} // DisplayMulticastAddresses
Good luck

Hi!
I've got a nice subject to work on but I can't find anything to help me.
I would like to determine my network location type on my laptop (domain, public, private) and get a few information on the active networks connections. So i think i have to use the NLA API but i haven't been able to manage all these structures and methods in c#.
Can someone help me please
Regards
Julien Choplin
Also try windows\system32\netstat.exe
Thanks a lot! It really helped me, but only to find a workaround 
In fact, with these namespaces (System.Net.Security and System.Net.NetworkInformation), i can't find if i'm in one of the three location types given by windows vista (Domain Profile, Private Profile, and Public Profile). Have you got more informations about it do you know how i can detect it

I think you can find it in Control Panel==>Network And Internet==>Network Sharing Center.
And I think you are in Private Network by default. As far as the domain, it is my understanding it defaults to you computer name but you can set it up differently, if you have a domain name registered to your name. Perhaps somebody else will comment on this issue also.
mmm, i'm not that dumb. thanks.
i want to know it programmatically........ so this don't help me.
