如何以编程方式更改 ip 地址？

Question

我想使用下面的代码以编程方式更改我的 ip 地址，但我不知道 networkInterfaceName 的名称（作为参数）。我怎样才能得到它？ networkInterfaceName 到底代表什么？

    public bool SetIP(string networkInterfaceName, string ipAddress, string subnetMask, string gateway = null)
    {
        var networkInterface = NetworkInterface.GetAllNetworkInterfaces().FirstOrDefault(nw => nw.Name == networkInterfaceName);
        var ipProperties = networkInterface.GetIPProperties();
        var ipInfo = ipProperties.UnicastAddresses.FirstOrDefault(ip => ip.Address.AddressFamily == AddressFamily.InterNetwork);
        var currentIPaddress = ipInfo.Address.ToString();
        var currentSubnetMask = ipInfo.IPv4Mask.ToString();
        var isDHCPenabled = ipProperties.GetIPv4Properties().IsDhcpEnabled;

        if (!isDHCPenabled && currentIPaddress == ipAddress && currentSubnetMask == subnetMask)
            return true;    // no change necessary

        var process = new Process
        {
            StartInfo = new ProcessStartInfo("netsh", $"interface ip set address \"{networkInterfaceName}\" static {ipAddress} {subnetMask}" + (string.IsNullOrWhiteSpace(gateway) ? "" : $"{gateway} 1")) { Verb = "runas" }
        };
        process.Start();
        var successful = process.ExitCode == 0;
        process.Dispose();
        return successful;
    }

如果你想获得正确的接口名称，你应该从这里开始，阅读来自微软文档的文章：NetworkInterface Class 。您可以只从上面的站点实施一些代码片段，并在 SetIP 方法中选择适当的接口，而不是从方法参数中获取它。如果你需要在参数中获取它，它应该也很简单。您有很多属性可以识别您感兴趣的网络接口。
