To change IP and default gateway: 

 System.Diagnostics.Process process = new System.Diagnostics.Process();
 System.Diagnostics.ProcessStartInfo startInfo = new System.Diagnostics.ProcessStartInfo();
 startInfo.WindowStyle = System.Diagnostics.ProcessWindowStyle.Hidden;
 startInfo.FileName = "cmd.exe";
 startInfo.Arguments = "netsh int ip set address \"local area connection\" static 192.168.0.101      255.255.255.0 192.168.0.254 1 ";
 process.StartInfo = startInfo;
 process.Start();

Please look here if you want to change the setting from the command line (can be scripted). Or you might want to use Powershell using this example.

Try EnableStatic and SetGateways of WMIObject Win32_NetworkAdapterConfiguration. The methods allows to configure the computer to use specific static IP address.

To tell the trust, one needn't set some static IP address in the most cases. One gets IP address from DHCP. One can use IpReleaseAddress and IpRenewAddress of iphlpapi in the case. I should remark that there is undocumented function SetAdapterIpAddress exported by IpHlpApi.dll, but I think that the usage of documented WMI method EnableStatic is better.
