使用c#和.Net API设置网络接口的IP地址

using System;
using System.Net;
using System.Net.NetworkInformation;

public class NetworkInterfaceExample
{
    public static void Main()
    {
        string interfaceName = "Ethernet"; // 网络接口名称
        string ipAddress = "192.168.0.100"; // 设置的IP地址
        string subnetMask = "255.255.255.0"; // 子网掩码

        NetworkInterface networkInterface = NetworkInterface.GetAllNetworkInterfaces()
            .FirstOrDefault(ni => ni.Name.Equals(interfaceName, StringComparison.OrdinalIgnoreCase));

        if (networkInterface != null)
        {
            IPInterfaceProperties ipProperties = networkInterface.GetIPProperties();
            UnicastIPAddressInformation ipAddressInfo = ipProperties.UnicastAddresses
                .FirstOrDefault(ip => ip.Address.AddressFamily == System.Net.Sockets.AddressFamily.InterNetwork);

            if (ipAddressInfo != null)
            {
                IPAddress newIpAddress = IPAddress.Parse(ipAddress);
                IPAddress newSubnetMask = IPAddress.Parse(subnetMask);

                ipProperties.UnicastAddresses.Remove(ipAddressInfo); // 移除旧的IP地址

                ipProperties.UnicastAddresses.Add(new UnicastIPAddressInformation(newIpAddress, newSubnetMask)); // 添加新的IP地址

                networkInterface.SetIPProperties(ipProperties); // 更新网络接口的IP地址配置

                Console.WriteLine("IP地址设置成功！");
            }
            else
            {
                Console.WriteLine("未找到指定的网络接口IP地址信息！");
            }
        }
        else
        {
            Console.WriteLine("未找到指定的网络接口！");
        }
    }
}
