Is there a generic swap method in the framework?

Question

Does a method like this exist anywhere in the framework?

public static void Swap<T>(ref T left, ref T right) {
    T temp;
    temp = left;
    left = right;
    right = temp;
}

If not, any reason why?

Answer 1

There is Interlocked.Exchange. This does it in a thread-safe, atomic call.

Edit after comments:

Just to clarify how this works using Interlocked.Exchange, you would do:

left = Interlocked.Exchange(ref right, left);

This will be the equivalent (in effect) to doing:

Swap(ref left, ref right);

However, Interlocked.Exchange does this as an atomic operation, so it's threadsafe.
