unity 获取本机的IP子网掩码网关

你可以使用以下代码获取本机的IP地址、子网掩码和网关：

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

public void GetIPAddress()
{
    string ipAddress = "";
    string subnetMask = "";
    string gateway = "";

    NetworkInterface[] networkInterfaces = NetworkInterface.GetAllNetworkInterfaces();
    foreach (NetworkInterface networkInterface in networkInterfaces)
    {
        if (networkInterface.NetworkInterfaceType == NetworkInterfaceType.Wireless80211 || networkInterface.NetworkInterfaceType == NetworkInterfaceType.Ethernet)
        {
            IPInterfaceProperties ipProperties = networkInterface.GetIPProperties();
            foreach (UnicastIPAddressInformation ipAddressInformation in ipProperties.UnicastAddresses)
            {
                if (ipAddressInformation.Address.AddressFamily == System.Net.Sockets.AddressFamily.InterNetwork)
                {
                    ipAddress = ipAddressInformation.Address.ToString();
                    subnetMask = ipAddressInformation.IPv4Mask.ToString();
                    break;
                }
            }

            foreach (GatewayIPAddressInformation gatewayIpAddressInformation in ipProperties.GatewayAddresses)
            {
                gateway = gatewayIpAddressInformation.Address.ToString();
                break;
            }
        }
    }

    Debug.Log("IP address: " + ipAddress);
    Debug.Log("Subnet mask: " + subnetMask);
    Debug.Log("Gateway: " + gateway);
}

注意，此代码仅适用于获取 IPv4 地址。如果你需要获取 IPv6 地址，需要相应地修改代码。
