网络性能信息，乍一看，好像很复杂的样子，本来还想走《主机性能监控系统--6.获取磁盘性能信息》的简单路线，不过看到“哎呀呀”同学在《主机性能监控系统--6.获取磁盘性能信息》发表的评论，觉得也是，性能信息和基本信息是有差别的，所以，在网络性能信息这个小程序里多了很多跟网络性能有关的信息，OK，废话不多说，先看效果图
在这个小程序中获取网络性能信息的方法是利用PerformanceCounter 这个类，这个类所获取的数据跟Windows自带的性能监视器所展示的数据很相近，所以应该还算是准确吧，哈哈，不过找不到那些英文单词比较准确的中文资料，所以，就自己蛮翻译了一下了。
OK，开始上代码，同样的，新建一个类，命名为：NetInfo，类图和代码如下：
NetInfo
public class NetInfo 
{
NetPerformanceStruct netPerformanceStruct;
定义PerformanceCounter#region 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();
