WMI or How to change my IP address

i'm looking for a way to change the local ip address auf my notebook. i'd
like to write some code that can change my configuration from static ip to
an dhcp configuration. looked at System.Managment, but i've got no idea how
this wmi thing works.

maybe you can help?

thanx marco

VERY simplified WMI sample:
// ===============================================================================
using System;
using System.Management;
using System.Threading;

namespace WmiIpChanger
{
class IpChanger
{
[MTAThread]
static void Main(string[] args)
{
ReportIP();
// SwitchToDHCP();
SwitchToStatic();
Thread.Sleep( 5000 );
ReportIP();
Console.WriteLine( "end." );
}

static void SwitchToDHCP()
{
ManagementBaseObject inPar = null;
ManagementBaseObject outPar = null;
ManagementClass mc = new ManagementClass("Win32_NetworkAdapterConfiguration");
ManagementObjectCollection moc = mc.GetInstances();
foreach( ManagementObject mo in moc )
{
if( ! (bool) mo["IPEnabled"] )
continue;

inPar = mo.GetMethodParameters("EnableDHCP");
outPar = mo.InvokeMethod( "EnableDHCP", inPar, null );
break;
}
}

static void SwitchToStatic()
{
ManagementBaseObject inPar = null;
ManagementBaseObject outPar = null;
ManagementClass mc = new ManagementClass("Win32_NetworkAdapterConfiguration");
ManagementObjectCollection moc = mc.GetInstances();
foreach( ManagementObject mo in moc )
{
if( ! (bool) mo[ "IPEnabled" ] )
continue;

inPar = mo.GetMethodParameters( "EnableStatic" );
inPar["IPAddress"] = new string[] { "192.168.1.1" };
inPar["SubnetMask"] = new string[] { "255.255.255.0" };
outPar = mo.InvokeMethod( "EnableStatic", inPar, null );
break;
}
}

static void ReportIP()
{
Console.WriteLine( "****** Current IP addresses:" );
ManagementClass mc = new ManagementClass("Win32_NetworkAdapterConfiguration");
ManagementObjectCollection moc = mc.GetInstances();
foreach( ManagementObject mo in moc )
{
if( ! (bool) mo[ "IPEnabled" ] )
continue;

Console.WriteLine( "{0}\n SVC: '{1}' MAC: [{2}]", (string) mo["Caption"],
(string) mo["ServiceName"], (string) mo["MACAddress"] );

string[] addresses = (string[]) mo[ "IPAddress" ];
string[] subnets = (string[]) mo[ "IPSubnet" ];

Console.WriteLine( " Addresses :" );
foreach(string sad in addresses)
Console.WriteLine( "\t'{0}'", sad );

Console.WriteLine( " Subnets :" );
foreach(string sub in subnets )
Console.WriteLine( "\t'{0}'", sub );
}
}
}
}

I found a sample at
http://cwashington.netreach.net/depo/view.asp?Index=628&ScriptType=vbscript.
Though it is VBScript, you may get hints from it.

Hope this helps.

Regards,
Max
