            {

                mac_src = mac_src.Insert(, "");

            }

            string mac_dest = "";

            for (int i = ; i < ; i++)

            {

                if ( == (i % ))

                {

                    if (i == )

                    {

                        mac_dest = mac_dest.Insert(, mac_src.Substring(i, ));

                    }

                    else

                    {

                        mac_dest = "-" + mac_dest.Insert(, mac_src.Substring(i, ));

                    }

                }

            }

            return mac_dest;

        }

    }

}

今天才发现 MAC 地址是 16 进制的。

macinfo.ToString("X") 获得居然是倒过来的 mac 地址

测试有点失败，只能是局域网的mac,不是广域网的mac

ToString("X") 就是显示为16 进制。参见：

http://msdn.microsoft.com/zh-cn/library/1fd69cbc(v=vs.110).aspx

        string GetMacAddress()

        {

            try

            {

                string mac = "";

                ManagementClass mc = new ManagementClass("Win32_NetworkAdapterConfiguration");

                ManagementObjectCollection moc = mc.GetInstances();

                foreach (ManagementObject mo in moc)

                {

                    if ((bool)mo["IPEnabled"] == true)

                    {

                        mac = mo["MacAddress"].ToString();

                        break;

                    }

                }

                moc = null;

                mc = null;

                return mac;

            }

            catch

            {

                return "unknow";

            }

        }

这种方法是获取服务器的MAC

方式三：通过javascript加载ActiveX来实现：

优点：任意获取mac地址（可以跨网段获取）；

缺点：需要在客户端浏览器中将activeX的选项全部打开，否则获取不到，所以不怎么稳定；

后台代码：（WebForm3.aspx.cs）

运行提示:

启用未标记为可安全执行脚本的ActiveX 第一步：工具->Internet选项第二步：安全->Internet->自定义级别第三步：启用“对未标记为可安全执行脚本的ActiveX控件初始化并执行”，如下图所示：

运行结果：

第三种未测试,这种太不人性化了，而且不安全

现在打算搞 c# 插件开发

百度搜索网页插件开发 c#

找到了几个案例，唉，我试验失败
