Hi,
I've been trying to write a code to change my IP address, but when I run my code the IP address is the same as before. can anybody help me to understand what's wrong?
thanks.

code:

private void Form1_Load(object sender, EventArgs e)
{
    textBox1.Text = getip();
    setIP("192.168.97.51","255.255.255.0");
    textBox2.Text = getip();
}
public string getip()
{
    IPHostEntry host;
    string localIP = "?";
    host = Dns.GetHostEntry(Dns.GetHostName());
    foreach (IPAddress ip in host.AddressList)
    {
        if (ip.AddressFamily.ToString() == "InterNetwork")
        {
            localIP = ip.ToString();
        }
    }
    return localIP;
}
public void setIP(string ip_address, string subnet_mask)
{
    ManagementClass objMC = new ManagementClass("Win32_NetworkAdapterConfiguration");
    ManagementObjectCollection objMOC = objMC.GetInstances();

    foreach (ManagementObject objMO in objMOC)
    {
        if ((bool)objMO["IPEnabled"])
        {
            ManagementBaseObject setIP;
            ManagementBaseObject newIP =
                objMO.GetMethodParameters("EnableStatic");

            newIP["IPAddress"] = new string[] { ip_address };
            newIP["SubnetMask"] = new string[] { subnet_mask };

            setIP = objMO.InvokeMethod("EnableStatic", newIP, null);
        }
    }
}

This is the right way! but check "ipenabled" criteria of the NIC

newIP[ "IPAddress" ] = IpAddresses.Split( ',' );

C#

newIP[ "IPAddress" ] = IpAddresses.Split( ',' );
newIP[ "SubnetMask" ] = new string[] { SubnetMask };

setIP = mo.InvokeMethod( "EnableStatic", newIP, null);
