C#更改本地网络适配器IP

可以使用C#中的`ManagementObject`类来更改本地网络适配器IP地址。以下是一个示例代码：

using System.Management;

public static void SetIP(string ipAddress, string subnetMask, string gateway, string dns)
{
    ManagementClass mc = new ManagementClass("Win32_NetworkAdapterConfiguration");
    ManagementObjectCollection moc = mc.GetInstances();

    foreach (ManagementObject mo in moc)
    {
        if ((bool)mo["IPEnabled"])
        {
            ManagementBaseObject newIP = mo.GetMethodParameters("EnableStatic");

            newIP["IPAddress"] = new string[] { ipAddress };
            newIP["SubnetMask"] = new string[] { subnetMask };

            ManagementBaseObject newGateway = mo.GetMethodParameters("SetGateways");
            newGateway["DefaultIPGateway"] = new string[] { gateway };
            newGateway["GatewayCostMetric"] = new int[] { 1 };

            ManagementBaseObject newDNS = mo.GetMethodParameters("SetDNSServerSearchOrder");
            newDNS["DNSServerSearchOrder"] = new string[] { dns };

            ManagementBaseObject setIP = mo.InvokeMethod("EnableStatic", newIP, null);
            ManagementBaseObject setGateway = mo.InvokeMethod("SetGateways", newGateway, null);
            ManagementBaseObject setDNS = mo.InvokeMethod("SetDNSServerSearchOrder", newDNS, null);
        }
    }
}

其中`ipAddress`，`subnetMask`，`gateway`和`dns`分别是你要设置的IP地址、子网掩码、网关和DNS服务器地址。你需要以管理员权限运行此代码才能更改网络适配器的配置。
