能不能帮我修改一下这个C#程序…很简单的……
这个是VS2008 WINDOWS文件，是一个流量监控程序，左边显示是当前所有网关的列表，点击之后可以在右边出现他的流量下载或上传情况，现在我不想要列表，只想她显示一个端口就好，端口名字是：Intel(R) WiFi 链接 5100 AGN，Interface Number是1，希望大虾们帮忙修改下…就是修改一个例子…急的快哭了……改简单点……谢谢…有3段代码…FormMain.cs的using System;

你可以直接把你所希望的网卡适配器的值传给它
其他的值就不要传了，清除掉
界面上把列表的控件直接屏蔽掉就可以了，做个按钮，直接用于显示你需要显示的那个网卡 --------------------编程问答-------------------- up up up --------------------编程问答-------------------- 代码好长 --------------------编程问答-------------------- up up up up up --------------------编程问答-------------------- mark --------------------编程问答-------------------- 看看这个例子，是否对你有参考价值？
