我不知道为什么,但是许多计算机都挂在以下操作上:
void Init()
{
net1 = new List<PerformanceCounter>();
net2 = new List<PerformanceCounter>();
foreach (string instance in new PerformanceCounterCategory("Network Interface").GetInstanceNames())
{
net1.Add(new PerformanceCounter("Network Interface", "Bytes Received/sec", instance));
net2.Add(new PerformanceCounter("Network Interface", "Bytes Sent/sec", instance));
}
}
//Once in 1 second
void UpdateStats()
{
Status.Text = "";
for (int i = 0; i < net1.Count; i++)
Status.Text += string.Format("{0}/{1} Kb/sec; ", net1[i].NextValue() / 1024, net2[i].NextValue() / 1024);
}
在某些计算程序上,程序在第一次调用时完全挂起UpdateStats()
,而另一些则经历 100% 的 CPU 负载,但程序工作(缓慢)。其他计数器new PerformanceCounter("Processor", "% Processor Time", "_Total")
似乎工作正常。
任何建议为什么会这样?
