Question

我想在下面使用此代码以编程方式更改我的IP地址，但我不知道networkInterfaceName（作为参数）的名称。我如何获得它？无论如何，networkInterfaceName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;
    }

如果要获取正确的接口名称，则应从Microsoft文档NetworkInterface Class 阅读文章，从这里开始。您可以仅从上述站点实现一些代码片段，然后在SetIP方法中选择适当的接口，而不是从方法参数中获取它。如果您需要获得参数，它也应该非常简单。您有很多属性可以识别您感兴趣的网络接口。
