在软件开发中可以会用到mac地址作为，设备的唯一标示，我们也可以通过unity获取，经测试pc，ios都可以但是安卓没有获取到。

代码如下：

using UnityEngine;using System.Collections;using System.Net.NetworkInformation;public class NetWorkInfo : MonoBehaviour{    void Start()    {        Debug.Log(GetMacAddress());    }    public static string GetMacAddress()    {        string physicalAddress = "";        NetworkInterface[] nice = NetworkInterface.GetAllNetworkInterfaces();        foreach (NetworkInterface adaper in nice)        {            Debug.Log(adaper.Description);            if (adaper.Description == "en0")            {                physicalAddress = adaper.GetPhysicalAddress().ToString();                break;            }            else            {                physicalAddress = adaper.GetPhysicalAddress().ToString();                if (physicalAddress != "")                {                    break;                };            }        }        return physicalAddress;    } void OnGUI()     {        GUI.Label(new Rect(0, 0, 200, 100), "MAC=" + GetMacAddress());    }}

补充说明：

using UnityEngine;using System.Collections;using System.Net.NetworkInformation;public class Test : MonoBehaviour {    void Start() {        NetworkInterface[] nis = NetworkInterface.GetAllNetworkInterfaces();        foreach (NetworkInterface ni in nis) {            Debug.Log ("Name = " + ni.Name);            Debug.Log ("Des = " + ni.Description);            Debug.Log ("Type = " + ni.NetworkInterfaceType.ToString() );            Debug.Log ("Mac地址 = " + ni.GetPhysicalAddress().ToString() );            Debug.Log ("------------------------------------------------");        }    }}
