C＃后台进程CPU负载使用PerformanceCounter

我想获得CPU负载的后台进程; Background process C＃后台进程CPU负载使用PerformanceCounter

使用性能计数器

PerformanceCounter ramCounter = new PerformanceCounter("Process", "Working Set", process.ProcessName); 
      PerformanceCounter cpuCounter = new PerformanceCounter("Process", "% Processor Time", process.ProcessName); 
      ramCounter.NextValue(); 
      cpuCounter.NextValue(); 
      while (true) 
      { 
       Thread.Sleep(500); 
       double ram = ramCounter.NextValue(); 
       double cpu = cpuCounter.NextValue(); 
       Console.WriteLine("RAM: " + (ram/1024/1024) + " MB; CPU: " + (cpu) + " %"); 
      }

它确实相当不错的软件（Apps），但却未能在Backgorund返回每次0; 我很困惑; 什么是正确的方式来检索CPU类型的过程？

检查这个例子

string processNameYourAreLookingFor ="name"; List<Process> prc_Aspx = runningNow.Where(x => x.ProcessName == processNameYourAreLookingFor).ToList(); foreach (Process process in prc_Aspx) { string _prcName = GetProcessInstanceName(process.Id); new PerformanceCounter("Process", "% Processor Time", _prcName);} }

而且GetProcessInstanceName。 http://www.codeproject.com/Articles/10258/How-to-get-CPU-usage-of-processes-and-threads – active92

该进程有几个活动实例，都具有相同的名称。那么你究竟在监视哪一个？ http://stackoverflow.com/a/9115662/17034 –

我正在运行抛出所有这些，结果是相同的0 cpu负载; 'List prc = runningNow.Where（x => x.ProcessName == txtApp.Text）.ToList（）; foreach（处理过程在prc中） {..' – MultyPulty

其实汉斯帕斯特给了我一个很好的提示; 所以这个问题不是在后台进程中，而是在具有相同ProcessName的多个实例。所以为了创建性能计数器，你应该通过进程ID换句话说获得流程实例名，由ID

private string GetProcessInstanceName(int pid) 
     { 
      PerformanceCounterCategory cat = new PerformanceCounterCategory("Process"); 

      string[] instances = cat.GetInstanceNames(); 
      foreach (string instance in instances) 
      { 

       using (PerformanceCounter cnt = new PerformanceCounter("Process", 
        "ID Process", instance, true)) 
       { 
        int val = (int)cnt.RawValue; 
        if (val == pid) 
        { 
         return instance; 
        } 
       } 
      } 
      throw new Exception("Could not find performance counter " + 
       "instance name for current process. This is truly strange ..."); 
     }
