上周，Boss和我说，他儿子夜里爬起来用笔记本在被窝里玩CF，问路由器可以解决么，我看了是TPLINK的普通家用无线路由器，不支持禁用CF客户端网游，可以通过配置端口屏蔽什么的，但是白天又要开启，想想麻烦。还是写个win服务，定时禁用网卡和定时启用网卡。

思路是分为两步，

1. 要先获取到无线网卡的ID。

2. 然后定时关闭/启用这个无线网卡。

程序呢，也是分为2部分，

1. 用了winform 去获取所有网络适配器信息，看看找到无线网卡，然后记下网卡名。

2. 用win服务去遍历Win32_NetworkAdapter 的信息，符合网卡的，就InvokeMethod， Disable/Enable 。

很简单，winform程序就遍历了下Win32_NetworkAdapter，然后2个按钮来测试是否可以正常关闭和开启无线网卡。

有点需要注意，需要引用System.Management.dll ，using System.Management;

 /// <summary>

         /// 网卡列表

         /// </summary>

         public void NetWorkList()

         {

             string manage = "SELECT * From Win32_NetworkAdapter";

             ManagementObjectSearcher searcher = new ManagementObjectSearcher(manage);

             ManagementObjectCollection collection = searcher.Get();

             List<string> netWorkList = new List<string>();

             foreach (ManagementObject obj in collection)

             {

                 netWorkList.Add(obj["Name"].ToString());

                 label5.Text += obj["Name"].ToString() + "\r\n";

             }

             this.cmbNetWork.DataSource = netWorkList;

         }

         /// <summary>

         public bool NetWorkState(string netWorkName)

         {

             string netState = "SELECT * From Win32_NetworkAdapter";

             ManagementObjectSearcher searcher = new ManagementObjectSearcher(netState);

             ManagementObjectCollection collection = searcher.Get();

             foreach (ManagementObject manage in collection)

             {

                 if (manage["Name"].ToString() == netWorkName)

                 {

                     return true;

                 }

             }

             return false;

         }

         /// <summary>

         public ManagementObject NetWork(string networkname)

         {

             string netState = "SELECT * From Win32_NetworkAdapter";

             ManagementObjectSearcher searcher = new ManagementObjectSearcher(netState);

             ManagementObjectCollection collection = searcher.Get();

             foreach (ManagementObject manage in collection)

             {

                 if (manage["Name"].ToString() == networkname)

                 {

                     return manage;

                 }

             }

             return null;

         }
