unity 获取本机IP

//工具脚本1：

using System;
using System.Collections;
using System.Collections.Generic;
using System.Net.NetworkInformation;
using System.Net.Sockets;
using UnityEngine;

public class GeIP
{
    public enum address
    {
        IPv4, IPv6
    }
     /// <summary>
     /// 获取本机IP
     /// </summary>
     /// <param name="Addfam">要获取的IP类型</param>
     /// <returns></returns>
     public static string IP(address fam)
     {
         if (fam== address .IPv6 && !Socket.OSSupportsIPv6)
         {
             return null;
         }
         string output = "";
        foreach (NetworkInterface item in NetworkInterface.GetAllNetworkInterfaces())
        {
             NetworkInterfaceType _type1 = NetworkInterfaceType.Wireless80211;
             NetworkInterfaceType _type2 = NetworkInterfaceType.Ethernet;
 
             if ((item.NetworkInterfaceType == _type1 || item.NetworkInterfaceType == _type2) && item.OperationalStatus == OperationalStatus.Up)
             {
                 foreach (UnicastIPAddressInformation ip in item.GetIPProperties().UnicastAddresses)
                 {
                     if (fam== address.IPv4)
                     {
                         if (ip.Address.AddressFamily == AddressFamily.InterNetwork)
                         {
                             output = ip.Address.ToString();
                         }
                     }
                     else if (fam== address.IPv6)
                     {
                         if (ip.Address.AddressFamily == AddressFamily.InterNetworkV6)
                         {
                             output = ip.Address.ToString();
                         }
                     }
                 }
             }
        }
         return output;
     }
}

调用

using static GeIP;
public class Ip : MonoBehaviour
{
    private string infoText;
    void Start()
    {
        infoText = GeIP.IP(address.IPv4);
    }
    private void EndValue(string value)
    {
        InputText = value; //捕捉数据，方便后续操作
        Debug.Log("IP内容" + value);
    }
}

写法二：

 private string[] GetLocalIpv4()
    {
        IPAddress[] localIPs;
        localIPs = Dns.GetHostAddresses(Dns.GetHostName());
        StringCollection IpCollection = new StringCollection();
        foreach (IPAddress ip in localIPs)
        {
            //根据AddressFamily判断是否为ipv4(InterNetwork),如果是ipv6 则条件为 InterNetWorkV6
            if (ip.AddressFamily == AddressFamily.InterNetwork)
                IpCollection.Add(ip.ToString());
        }
        string[] IpArray = new string[IpCollection.Count];
        IpCollection.CopyTo(IpArray, 0);
        return IpArray;
    }

写法三：

  //获取本地ip
        string GetLocalIP()
        {
            NetworkInterface[] adapters = NetworkInterface.GetAllNetworkInterfaces();
            foreach (NetworkInterface adater in adapters)
            {
                if (adater.Supports((NetworkInterfaceComponent.IPv4)))
                {
                    UnicastIPAddressInformationCollection uniCast = adater.GetIPProperties().UnicastAddresses;
                    if (uniCast.Count > 0)
                    {
                        foreach (UnicastIPAddressInformation uni in uniCast)
                        {
                            if (uni.Address.AddressFamily == AddressFamily.InterNetwork)
                            {
                                return uni.Address.ToString();
                            }
                        }
                    }
                }
            }

            return "127.0.0.1";
        }
    }
