What does Thread.Join() do?

[liptonIcedTea]

I don't get it - the definition is that it "blocks the calling thread until a thread terminates"?

Does that mean it's kind of like a halt command where it'll sit and wait until the thread which it has put the join() on finish before it keeps going?

If so, it seems like a very strange name for this function.

It also does this:

This method changes the state of the calling thread to include ThreadState.WaitSleepJoin.

It's not a name that Microsoft have invented. It's standard programming terminology for the task it performs. Exactly where and when the name comes from I don't know but it's been around a lot longer than .NET.
