如何獲得C#中的CPU使用量？我希望得到C#中應用程序的總CPU使用量。我已經找到了很多方法來深入了解進程的屬性，但是我只想要進程的CPU使用情況，以及像TaskManager中那樣的CPU總量。

public class Form1{
int totalHits = 0;
public object getCPUCounter()
{
PerformanceCounter cpuCounter = new PerformanceCounter();
cpuCounter.CategoryName = "Processor";
cpuCounter.CounterName = "% Processor Time";
cpuCounter.InstanceName = "_Total";
// will always start at 0
dynamic firstValue = cpuCounter.NextValue();
System.Threading.Thread.Sleep(1000);
// now matches task manager reading
dynamic secondValue = cpuCounter.NextValue();
return secondValue;
}
private void Timer1_Tick(Object sender, EventArgs e)
{
int cpuPercent = getCPUCounter();
if (cpuPercent >= 90)
{
totalHits = totalHits + 1;
if (totalHits == 60)
{
Interaction.MsgBox("ALERT 90% usage for 1 minute");
totalHits = 0;
}
}
else
{
totalHits = 0;
}
Label1.Text = cpuPercent + " % CPU";
Label2.Text = getRAMCounter() + " RAM Free";
Label3.Text = totalHits + " seconds over 20% usage";
