在軟件開發中可以會用到mac地址作為，設備的唯一標示，我們也可以通過unity獲取，經測試pc，ios都可以但是安卓沒有獲取到。

代碼如下：

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());
    }
}

補充說明：

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 ("------------------------------------------------");
        }
    }
}
