Question

I have a method that for thread-safety reasons should only ever be used by a particular thread. If another thread tries to use it, I would like an exception to be thrown.

public void UnsafeMethod()
{
    if (CurrentThreadId != this.initialThreadId)
        throw new SomeException("Can only be run on the special thread.");
    // continue ...
}

How can I find the CurrentThreadId in the code above? Or alternatively is there some other way of achieving what I want to do?

Answer 1

Thread.CurrentThread.ManagedThreadId

Or you could just store a reference to the thread object itself and compare that to Thread.CurrentThread.
