Hi,
I have an application that needs to change the IP address of the local
computer.
How can I do this?

Regards,
Mystique
 
Mystique,

You will want to use the classes in the System.Management namespace to
get the instance of the Win32_NetworkAdapterConfiguration WMI class that
corresponds to the adapter. Once you have that, you can call the
EnableStatic method on the instance to set the IP address for the adapter.

Hope this helps.
 
Ok,
And how can make the application Obtain an IP automatically?

Hi Mystique

Maybe you find the code below useful. It shows your IP-address. I didn't try
EnableStatic because I didn't find it practical to run the risk corrupting
my machine...

Christiaan.



ManagementClass mc = new
ManagementClass("Win32_NetworkAdapterConfiguration");
ManagementObjectCollection moc = mc.GetInstances();
foreach(ManagementObject mo in moc)
{
Console.WriteLine("Description: {0}", mo["Description"].ToString());
if((bool)mo["IPEnabled"] == true)
{

string[] IPAddresses=(string[]) mo["IPAddress"];
for (int i=0;i<IPAddresses.Length;i++)
{
Console.WriteLine("+-> IpAddress {0} is:
{1}.",i.ToString(),IPAddresses);
}

Console.WriteLine("+-> MAC address: {0}", mo["MacAddress"].ToString());
}
mo.Dispose();
}

If an address is not static, it comes from a DHCP server on your network,
not from a DNS server. Calling EnableDHCP() on the network adapter will
probably do what you want. I didn't try it myself.

See: ms-help://MS.VSCC/MS.MSDNVS/wmisdk/r_32hard4_6oq6.htm
