用C#设置IP的一种方法

//here is the code to configure TCP/IP Settings using WMI

public static void setIP(string IPAddress,string SubnetMask, string Gateway)
{
 
ManagementClass objMC = new ManagementClass(
    "Win32_NetworkAdapterConfiguration");
ManagementObjectCollection objMOC = objMC.GetInstances();

foreach(ManagementObject objMO in objMOC)
{

      if (!(bool) objMO["IPEnabled"])
           continue;

 
      try
        {
          ManagementBaseObject objNewIP = null;
          ManagementBaseObject objSetIP = null;
          ManagementBaseObject objNewGate = null;

         
          objNewIP = objMO.GetMethodParameters("EnableStatic");
          objNewGate = objMO.GetMethodParameters("SetGateways");
         

          //Set DefaultGateway
          objNewGate["DefaultIPGateway"] = new string[] {Gateway};
          objNewGate["GatewayCostMetric"] = new int[] {1};
         

          //Set IPAddress and Subnet Mask
          objNewIP["IPAddress"] = new string[] {IPAddress};
          objNewIP["SubnetMask"] = new string[] {SubnetMask};
         
          objSetIP = objMO.InvokeMethod("EnableStatic",objNewIP,null);
          objSetIP = objMO.InvokeMethod("SetGateways",objNewGate,null);

         
          Console.WriteLine(
             "Updated IPAddress, SubnetMask and Default Gateway!");

       
        }
        catch(Exception ex)
        {
              MessageBox.Show("Unable to Set IP : " + ex.Message); }
        }

}
