Is there an equivalent of the lock{} statement for ReaderWriterLockSlim?

I like the shortcut in C# of lock(myLock){ /* do stuff */}. Is there an equivalent for read/write locks? (Specifically ReaderWriterLockSlim.) Right now, I use the following custom method, which I think works, but is kind of annoying because I have to pass in my action as an anonymous function, and I would prefer to use a standard locking mechanism if possible.

    void bool DoWithWriteLock(ReaderWriterLockSlim RWLock, int TimeOut, Action Fn)
    {
        bool holdingLock = false;
        try
        {
            if (RWLock.TryEnterWriteLock(TimeOut))
            {
                holdingLock = true;
                Fn();
            }
        }
        finally
        {
            if (holdingLock)
            {
                RWLock.ExitWriteLock();
            }
        }
        return holdingLock;
    }
