C#使用cmd更改IP地址

使用NetworkInterface.GetAllNetworkInterfaces获取所有除环回地址跟隧道适配器地址的地址，并显示在Listbox上，通过更改listBox1_MouseDoubleClick事件，如果listBox1.SelectedIndex的值不为-1，即有选中项时，遍历所有的地址，直到找到与选中项名字相同的为止，并将适配器信息传递给新窗体。

using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.Threading.Tasks;using System.Windows;using System.Windows.Controls;using System.Windows.Data;using System.Windows.Documents;using System.Windows.Input;using System.Windows.Media;using System.Windows.Media.Imaging;using System.Windows.Navigation;using System.Windows.Shapes;using System.Diagnostics;using System.Net;using System.Net.Sockets;using System.Net.NetworkInformation;namespace 修改IP地址{    /// <summary>    /// MainWindow.xaml 的交互逻辑    /// </summary>    public partial class MainWindow : Window    {        public MainWindow()        {            InitializeComponent();        }        private void Window_Loaded(object sender, RoutedEventArgs e)        {            NetworkInterface[] NwIfs = NetworkInterface.GetAllNetworkInterfaces();            foreach(NetworkInterface  NwIf in NwIfs)            {                if (NwIf.NetworkInterfaceType == NetworkInterfaceType.Loopback)                    continue;                if (NwIf.NetworkInterfaceType == NetworkInterfaceType.Tunnel)                    continue;                listBox1.Items.Add(NwIf.Name);            }        }        private void listBox1_MouseDoubleClick(object sender, MouseButtonEventArgs e)        {            if (listBox1.SelectedIndex != -1)            {                NetworkInterface[] NwIfs = NetworkInterface.GetAllNetworkInterfaces();                foreach (NetworkInterface NwIf in NwIfs)                {                    if (NwIf.Name == listBox1.SelectedItem.ToString())                    {                        IP Wd = new IP(NwIf);                        Wd.Show();                    }                }            }        }    }}

在新窗体中声明三个变量，记录改变地址前的数据，并使用TextBox显示出IP地址，子网掩码和默认网关。通过实例化process对象，打开cmd.exe，并输入命令行，格式为　netsh interface ip set address “本地连接 2” static ipv4 ipv4msk gateway* ，如果成功修改，则更新三个变量为当前IP地址，如果修改失败，则输出失败的结果，并通过三个变量将TextBox的值复原。

在写这个的过程中，因为少写了p.StandardOutput.ReadLine(); 以及输错命令行，导致出现了很多问题。以后对于这方面要加强警惕。
