c# - 类 PerformanceCounter 文档

Question

我在使用 PerformanceCounter 时遇到问题，我想获取 CPU 温度，但我只找到了这个:

PerformanceCounter tempCount = new PerformanceCounter(
    "Thermal Zone Information", 
    "Temperature", 
    @"\_TZ.THRM"); 

我还没有找到有关构造函数值“热区信息”的文档。在哪里可以找到 PerformanceCounter 的文档？

Answer 1

请参阅下面的示例，了解如何获取温度计数器的值:

我在性能监视器中为热区信息添加了计数器，如下所示:

这是我的控制台应用程序，它正在获取计数器的值:

using System;
using System.Diagnostics;
using System.Threading;

namespace ConsoleApp
{
    public class Program
    {
        public static void Main(params string[] args)
        {
            PerformanceCounterCategory performanceCounterCategory = new PerformanceCounterCategory("Thermal Zone Information");
            var instances = performanceCounterCategory.GetInstanceNames();
            List<PerformanceCounter> temperatureCounters = new List<PerformanceCounter>();
            foreach (string instanceName in instances)
            {

                foreach (PerformanceCounter counter in performanceCounterCategory.GetCounters(instanceName))
                {
                    if (counter.CounterName == "Temperature")
                    {
                        temperatureCounters.Add(counter);
                    }
                }
            }


            while(true)
            {
                foreach (PerformanceCounter counter in temperatureCounters)
                {
                    Console.WriteLine("{0} {1} {2} {3}",counter.CategoryName,counter.CounterName,counter.InstanceName, counter.NextValue());
                }
                Console.WriteLine();
                Console.WriteLine();
                Thread.Sleep(500);
            }
        }
    }
}

正如你所看到的，构造函数的值相应地是:

PerformanceCounter(
    "Thermal Zone Information",    // Object 
    "Temperature",                 // Counter
    @"\_TZ.TZ01")                  // Instance
