使用 Process PerformanceCounters，我如何知道实例与哪个进程关联？

查询“进程”性能计数器类别的实例时，可能存在同名进程的多个实例。

例如这段代码：

var cat = new PerformanceCounterCategory("Process");

var names = cat.GetInstanceNames();

foreach (var name in names)
    Console.WriteLine(name);

可能会打印这些结果： ... 探索我探索#1 我探索#2 我探索#3 ...

我如何知道每个计数器实例对应哪个进程？

原文

When querying instances for the the "Process" performance counter category there might be multiple instances of of a process with the same name.

For example this code:

var cat = new PerformanceCounterCategory("Process");

var names = cat.GetInstanceNames();

foreach (var name in names)
    Console.WriteLine(name);

Might print these results:
...
iexplore
iexplore#1
iexplore#2
iexplore#3
...

How do I know which process each of these counter instances corresponds to?

“进程”类别中有一个名为“ID Process”的 PerformanceCounter，它将返回性能计数器实例对应的进程的 pid。

var cat = new PerformanceCounterCategory("Process");

var names = cat.GetInstanceNames();

foreach (var name in names.OrderBy(n => n))
{
    var pidCounter = new PerformanceCounter("Process", "ID Process", name, true);
    var sample = pidCounter.NextSample();
    Console.WriteLine(name + ": " + sample.RawValue);
}

这将打印：

...
i探索：548
iexplore#1：1268
iexplore#2：4336
...

There is a PerformanceCounter named "ID Process" in the "Process" category that will return the pid of the process that the performance counter instance corresponds to.

var cat = new PerformanceCounterCategory("Process");

var names = cat.GetInstanceNames();

foreach (var name in names.OrderBy(n => n))
{
    var pidCounter = new PerformanceCounter("Process", "ID Process", name, true);
    var sample = pidCounter.NextSample();
    Console.WriteLine(name + ": " + sample.RawValue);
}

This will print:
