如何获得活动线程数? [英] How to get the active thread count?

问题描述

我有一个调用C ++库的程序.程序进程具有大量线程(50-60).它们中的大多数似乎是用C ++创建的，我怀疑大多数已暂停/正在等待.

I have a program which calls a C++ library. The program processes has a large number of threads (50 - 60). Most of them seem to be created in C++ and I suspect most are suspended/waiting.

在给定的时间点，我如何找到这些线程中有多少处于活动状态?

How do I find how many of these threads are active at a given point in time?

推荐答案

要真正确定活动线程的数量，必须检查每个线程的ThreadState属性.

To actually determine the count of active threads, it's necessary to check the ThreadState property of each thread.

((IEnumerable)System.Diagnostics.Process.GetCurrentProcess().Threads)
    .OfType<System.Diagnostics.ProcessThread>()
    .Where(t => t.ThreadState == System.Diagnostics.ThreadState.Running)
    .Count();
