如何设置网卡IP地址

本文关键字：网卡 IP 地址 设置 何设置 | 更新日期: 2023-09-27 18:15:23

为了玩局域网游戏和在家里上网，我不得不经常更换IP地址。我正在用c#创建一个可以快速完成的应用程序。我已经制作了适配器名称，IP地址，子网，DNS服务器地址等字段。我的代码运行在设置IP按钮点击如下:

string adapter = comboAdapterName.Text;
string ip = comboIPAddress.Text;
string subnet = comboSubnet.Text;
string dns = comboDNS.Text;

现在我想使用这个process方法从这些字段中获取数据，并相应地附加字符串。

Process p = new Process();
ProcessStartInfo psi = new ProcessStartInfo("netsh", "interface ip set address '"Local Area Connection'" static 192.168.0.10 255.255.255.0 192.168.0.1 1");
p.StartInfo = psi;
p.Start();

但我想这并不那么容易。因为我无法在不影响格式的情况下编辑它。此外，我还尝试使用许多+s创建一个全新的字符串，我可以像这样放置:

ProcessStartInfo psi = new ProcessStartInfo(mystring);

但是对我来说还是太难了。请建议一个简单的方法来做这件事。

我想我明白了:

string ipstring = "netsh interface ip set address " + "'"" + adapter + "'"" + " " + "static" + " " + ip + " " + subnet + " " + dns;

如何设置网卡IP地址

您需要使用String。格式的方法。

的例子:

string subnet = comboSubnet.Text;
string formatted = string.Format("Subnet is: {0}", subnet);
MessageBox.Show(formatted);

把字符串格式化成你想要的样子。

您可以使用以下功能获取当前适配器配置:

private static void EthernetInf(out string ip, out string dns, out string nic)  // To get current ethernet config
{
    ip = "";
    dns = "";
    nic = "";
    foreach (NetworkInterface ni in NetworkInterface.GetAllNetworkInterfaces())
    {
        if (ni.NetworkInterfaceType == NetworkInterfaceType.Ethernet)
        {
            foreach (IPAddress dnsAdress in ni.GetIPProperties().DnsAddresses)
            {
                if (dnsAdress.AddressFamily == System.Net.Sockets.AddressFamily.InterNetwork)
                {
                    dns = dnsAdress.ToString();
                }
            }

            foreach (UnicastIPAddressInformation ips in ni.GetIPProperties().UnicastAddresses)
            {
                if (ips.Address.AddressFamily == System.Net.Sockets.AddressFamily.InterNetwork && !ips.Address.ToString().StartsWith("169")) //to exclude automatic ips
                {
                    ip = ips.Address.ToString();
                    nic = ni.Name;
                }
            }
        }
    }

以下功能用于设置提升命令提示符中的IP:

private void SetIP(Button sender, string arg)  //To set IP with elevated cmd prompt
{
    try
    {
        if (sender.Background == Brushes.Cyan )
        { 
            MessageBox.Show("Already Selected...");
            return;
        }
        ProcessStartInfo psi = new ProcessStartInfo("cmd.exe");
        psi.UseShellExecute = true;
        psi.WindowStyle = ProcessWindowStyle.Hidden;
        psi.Verb = "runas";
        psi.Arguments = arg;
        Process.Start(psi);
        if (sender == EthStatic ||  sender == EthDHCP )
        {
            EthStatic.ClearValue(Button.BackgroundProperty);
            EthDHCP.ClearValue(Button.BackgroundProperty);
            sender.Background = Brushes.Cyan;
         }
        if (sender == WIFIStatic || sender == WIFIDhcp)
        {
            WIFIStatic.ClearValue(Button.BackgroundProperty);
            WIFIDhcp.ClearValue(Button.BackgroundProperty);
            sender.Background = Brushes.Cyan;
        }
    }
    catch(Exception ex)
    {
        MessageBox.Show(ex.Message);
    }

这个点击按钮代码将参数传递给processstartinfo以设置IP

private void EthStatic_Click(object sender, RoutedEventArgs e)
{
    SetIP(EthStatic, "/c netsh interface ip set address '"" + EthName + "'" static " + Properties.Settings.Default.EthIPac + " " + Properties.Settings.Default.Subnet + " " + Properties.Settings.Default.EthDnsac + " & netsh interface ip set dns '"" + EthName + "'" static " + Properties.Settings.Default.EthDnsac);

}
