Is there a straightforward way to have a thread-local instance variable?

Question

With the ThreadStatic attribute I can have a static member of a class with one instance of the object per thread. This is really handy for achieving thread safety using types of objects that don't guarantee thread-safe instance methods (e.g., System.Random).

It only works for static members, though. Is there any straightforward way to declare a class member as thread-local, meaning, each class instance gets an object per thread?

Looks like the ThreadLocal<T> class is what I was looking for.

And yes, I do feel a bit stupid for not knowing about this before now.

It's hardly stupid. The .net libraries are very broad. Only the very patient or very bored have read through the docs enough times to know everything that is available. A general sense of the types of functionality available combined with google are the best way to find the bits you rarely need. – ScottS Jun 07 '10 at 18:07
