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:）。

//本次改进主要部分，主要思路是通过PerformanceCounterCategory这个类来获取Network Interface下
//的所有实例(即网卡名称)，先将这个网卡名称处理掉所有的特殊字符，然后与传递进来的网卡名称(也处理掉特殊字符)
//进行比较，如果相同，就将符合格式的实例名称赋给网卡名称，接下去就是获取性能信息。。。
string[] instanceNames;
PerformanceCounterCategory mycat = new PerformanceCounterCategory("Network Interface");
try

接下来是窗体的代码：

NetInfo Form

public partial class NetInfoForm : Form
{
public NetInfoForm()
{
InitializeComponent();
}
ComputerInfo.NetInfo netinfo = new ComputerInfo.NetInfo();
string strNetName;
ComputerInfo.NetInfo.NetPerformanceStruct netInfoStruct;
List<ComputerInfo.NetInfo.NetInfoBaseStruct> lNetInfoBase;
private void NetInfoForm_Load(object sender, EventArgs e)
{
//获取网络基本信息

lNetInfoBase = netinfo.GetNetInfoBase();
//设置ListView的样式以及列
lvNet.View = View.Details;
lvNet.Columns.Add("项", 150);
lvNet.Columns.Add("值", 300);
lvNet.FullRowSelect = true;
lvNet.GridLines = true;

for (int i = 0; i < lNetInfoBase.Count; i++)
{
cbNetCard.Items.Add(lNetInfoBase[i].NetName);
}

//设置ListView的样式以及列
lvNetPerformance.View = View.Details;
lvNetPerformance.Columns.Add("项", 150);
lvNetPerformance.Columns.Add("值", 300);
lvNetPerformance.FullRowSelect = true;
lvNetPerformance.GridLines = true;

cbNetCard.SelectedIndex = 0;
}

private void NetInfotimer_Tick(object sender, EventArgs e)
{
try
{

netInfoStruct = netinfo.GetNetPerformance(strNetName);
}
catch (Exception ex)
{
NetInfotimer.Enabled = false;
MessageBox.Show(ex.Message + ex.StackTrace);
}
lvNetPerformance.Items.Clear();
//定义一些需要用到的项
ListViewItem lviBytesTotal = new ListViewItem(new string[] { "每秒字节总数", netInfoStruct.BytesTotal.ToString() });
ListViewItem lviBytesSent = new ListViewItem(new string[] { "每秒发送字节数", netInfoStruct.BytesSent.ToString() });

//将项添加到ListView控件里面
lvNetPerformance.Items.Add(lviBytesTotal);

lvNetPerformance.Items.Add(lviBytesReceived);
lvNetPerformance.Items.Add(lviPacketsTotal);

lvNetPerformance.Items.Add(lviPacketsReceivedDiscarded);
lvNetPerformance.Items.Add(lviPacketsReceivedErrors);

}

private void cbNetCard_SelectedIndexChanged(object sender, EventArgs e)
{
lvNet.Items.Clear();
int nSelectindex = cbNetCard.SelectedIndex;
strNetName = lNetInfoBase[nSelectindex].NetName;

//定义一些需要用到的项

OK，感谢各位同学提出建议，意见，以及BUG，如果您在调试过程中有遇到什么BUG的话，麻烦您跟我说下，以便把程序做好。谢谢~~~

当然，未完，待续~~~
