How to know threadid for each thread spawn by parallel.foreach

问题

I have a scenario something like this

int arr[100];

Parallel.Foreach(arr, (a) => { some processing});

Now, this code will spawn 100 child threads, how can I know thread id for each child thread in "some processing" logic.

回答1:

You could use

Thread.CurrentThread.ManagedThreadId 

but note that your parallel foreach is not forced to actually create 100 threads.
