主机性能监控系统--7.获取网络性能信息(升级版)

      感谢老虎爱吃鱼同学在《主机性能监控系统--7.获取网络性能信息》提出的BUG，这个问题确实是没有注意到，因为刚好我的网卡名字中都没有包含括号，斜线等特殊符号，而且由于时间仓促，也没有去虚机里面做测试，本篇作为升级版，首先解决了(我用包含有特殊符号的网卡做了测试)老虎爱吃鱼同学提出的BUG，并且修复一些之前没看到的小BUG，继而，增加了一个功能，就是当系统中存在多张网卡的时候，可以通过下拉框选择要查看网卡的信息。OK，效果图先秀下，由于是在虚机里面的截图，所以比较丑，不过能说明事情就好了:）。

      代码上改动不大，但是，还是贴上来下比较好，哈哈，类图就没什么大变化了，就不贴了，显示NetInfo这个类的代码，如下：

 

public class NetInfo
    {
        NetPerformanceStruct netPerformanceStruct;

        //定义PerformanceCounter
        PerformanceCounter pcBytesTotal = new PerformanceCounter();
        PerformanceCounter pcBytesSent = new PerformanceCounter();
        PerformanceCounter pcBytesReceived = new PerformanceCounter();
        PerformanceCounter pcPacketsTotal = new PerformanceCounter();
        PerformanceCounter pcPacketsSent = new PerformanceCounter();
        PerformanceCounter pcPacketsSentUnicast = new PerformanceCounter();
        PerformanceCounter pcPacketsSentNonUnicast = new PerformanceCounter();
        PerformanceCounter pcPacketsSentDiscarded = new PerformanceCounter();
        PerformanceCounter pcPacketsSentErrors = new PerformanceCounter();
        PerformanceCounter pcPacketsReceived = new PerformanceCounter();
        PerformanceCounter pcPacketsReceivedUnicast = new PerformanceCounter();
        PerformanceCounter pcPacketsReceivedNonUnicast = new PerformanceCounter();
        PerformanceCounter pcPacketsReceivedDiscarded = new PerformanceCounter();
        PerformanceCounter pcPacketsReceivedErrors = new PerformanceCounter();

        //构造函数
        public NetInfo()
        {

        }


        //网络基础信息结构体
        public struct NetInfoBaseStruct

        }

        public struct NetPerformanceStruct
        {
           //字节

            public float BytesSent;  //每秒发送字节数

            //包发送

            public float PacketsSentUnicast;  //每秒发送单播包数
            public float PacketsSentNonUnicast;  //每秒发送非单播包数
            public float PacketsSentDiscarded;  //被丢弃的发送包数
            public float PacketsSentErrors;  //错误的发送包数


           //包接收
            public float PacketsReceived;  //每秒接收包数
            public float PacketsReceivedUnicast;  //每秒接收单播包数
