static void Main(string[] args)
{
PerformanceCounter myAppCpu =
new PerformanceCounter("Process", "% Processor Time", "OUTLOOK", true);
// will always start at 0
float firstValue = cpuCounter.NextValue();
System.Threading.Thread.Sleep(1000);
// now matches task manager reading
int secondValue = (int)cpuCounter.NextValue();
}
对于整个系统CPU,我有
PerformanceCounter cpuCounter = new PerformanceCounter();
cpuCounter.CategoryName = "Processor";
cpuCounter.CounterName = "% Processor Time";
cpuCounter.InstanceName = "_Total";
// will always start at 0
float firstValue = cpuCounter.NextValue();
System.Threading.Thread.Sleep(1000);
// now matches task manager reading
int secondValue = (int)cpuCounter.NextValue();
有什么方法可以找到大多数CPU消耗过程吗?
解决方法:
using System;
using System.Linq;
using System.Threading;
using System.Diagnostics;
using System.Collections.Generic;
namespace ProcessCount
{
static class Program
{
static void Main()
{
var counterList = new List<PerformanceCounter>();
while (true)
{
var procDict = new Dictionary<string, float>();
Process.GetProcesses().ToList().ForEach(p =>
{
using (p)
if (counterList
.FirstOrDefault(c => c.InstanceName == p.ProcessName) == null)
counterList.Add(
new PerformanceCounter("Process", "% Processor Time",
p.ProcessName, true));
});
counterList.ForEach(c =>
{
try
{
// http://social.technet.microsoft.com/wiki/contents/
// articles/12984.understanding-processor-processor-
// time-and-process-processor-time.aspx
// This value is calculated over the base line of
// (No of Logical CPUS * 100), So this is going to be a
// calculated over a baseline of more than 100.
var percent = c.NextValue() / Environment.ProcessorCount;
if (percent == 0)
return;
// Uncomment if you want to filter the "Idle" process
//if (c.InstanceName.Trim().ToLower() == "idle")
// return;
procDict[c.InstanceName] = percent;
}
catch (InvalidOperationException) { /* some will fail */ }
});
Console.Clear();
procDict.OrderByDescending(d => d.Value).ToList()
.ForEach(d => Console.WriteLine("{0:00.00}% - {1}", d.Value, d.Key));
Thread.Sleep(1000);
}
}
}
}
