C#动态更改IP地址

首先要添加System.Management引用。

 

using System;
using System.Collections.Generic;
using System.Text;
using System.Management;
using System.Management.Instrumentation;
using System.Collections;

 

 

 

class Program
    {
        static void Main(string[] args)
        {

            SetNetworkAdapter();

            Console.Read();

        }

        static void SetNetworkAdapter()
        {
            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;

                //设置ip地址和子网掩码 
                inPar = mo.GetMethodParameters("EnableStatic");
                inPar["IPAddress"] = new string[] { "192.168.10.248", "192.168.10.249" };// 1.备用 2.IP
                inPar["SubnetMask"] = new string[] { "255.255.255.0", "255.255.255.0" };
                outPar = mo.InvokeMethod("EnableStatic", inPar, null);

                //设置网关地址 
                inPar = mo.GetMethodParameters("SetGateways");
                inPar["DefaultIPGateway"] = new string[] { "192.168.10.254", "192.168.10.254" }; // 1.网关;2.备用网关
                outPar = mo.InvokeMethod("SetGateways", inPar, null);

                //设置DNS 
                inPar = mo.GetMethodParameters("SetDNSServerSearchOrder");
                inPar["DNSServerSearchOrder"] = new string[] { "221.5.203.98", "221.5.203.98" }; // 1.DNS 2.备用DNS
                outPar = mo.InvokeMethod("SetDNSServerSearchOrder", inPar, null);
                break;
            }
        }

    }
