c# 本机IP修改

校园网总是要修改ip 去实验室也要修改ip 想着编一个IP修改的软件比较方便

我用的是 using System.Management;  报错的话记得在项目的引用中添加

右击 引用---添加引用---System.Management

private void setbendi(string[] ip, string[] yanma, string[] wangguan, string[] dns)
        {
            ManagementBaseObject inPar = null;
            ManagementBaseObject outPar = null;
            ManagementClass mc = new ManagementClass("Win32_NetworkAdapterConfiguration");
            ManagementObjectCollection moc = mc.GetInstances();
            foreach (ManagementObject mo in moc)
            {
                //设置本地连接                        //设置别的可以修改以下参数
                if (mo["Description"].ToString() == "Realtek PCIe GBE Family Controller")
                {
                    //设置ip地址和子网掩码
                    if (ip != null && yanma != null)
                    {
                        inPar = mo.GetMethodParameters("EnableStatic");
                        inPar["IPAddress"] = ip;
                        inPar["SubnetMask"] = yanma;
                        outPar = mo.InvokeMethod("EnableStatic", inPar, null);
                    }
                    //设置网关地址 
                    if (wangguan != null)
                    {
                        inPar = mo.GetMethodParameters("SetGateways");
                        inPar["DefaultIPGateway"] = wangguan;
                        outPar = mo.InvokeMethod("SetGateways", inPar, null);
                    }
                    //设置DNS 
                    if (dns != null)
                    {
                        inPar = mo.GetMethodParameters("SetDNSServerSearchOrder");
                        inPar["DNSServerSearchOrder"] = dns;
                        outPar = mo.InvokeMethod("SetDNSServerSearchOrder", inPar, null);
                    }
                    MessageBox.Show("成功设置IP");
                }
            }
        }

以上就是主要代码  只能修改本地连接 ip4
