I have an application written in C# that needs to be able to configure the network adapters in Windows. I have this basically working through WMI, but there are a couple of things I don't like about that solution: sometimes the settings don't seem to stick, and when the network cable is not plugged in, errors are returned from the WMI methods, so I can't tell if they really succeeded or not.
I need to be able to configure all of the settings available through the network connections - Properties - TCP/IP screens.
What's the best way to do this?
You could use Process to fire off netsh commands to set all the properties in the network dialogs.
eg: To set a static ipaddress on an adapter
netsh interface ip set address "Local Area Connection" static 192.168.0.10 255.255.255.0 192.168.0.1 1
To set it to dhcp you'd use
netsh interface ip set address "Local Area Connection" dhcp
To do it from C# would be
Process p = new Process();
ProcessStartInfo psi = new ProcessStartInfo("netsh", "interface ip set address \"Local Area Connection\" static 192.168.0.10 255.255.255.0 192.168.0.1 1");
p.StartInfo = psi;
p.Start();
Setting to static can take a good couple of seconds to complete so if you need to, make sure you wait for the process to exit.
