c# - .NET Is there a way to get the parent thread id?

Question

Suppose the main thread is spawning a new thread t1, how can my code that runs on t1 find the thread id of the main thread (using c#)?

Edit:
I don't control the creation of the new thread. So I can't pass any parameters to the thread.

Thanks.

Answer 1

You can't.

Yet you might consider:

1. Prefix the name of the new thread with the thread ID from the parent thread
2. Create a constructor on the method you want to spawn that requires the thread ID from the parent
