unity基础开发----Unity获取PC，Ios系统的mac地址等信息

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