Disposing an Injected Constructor Object

Question

Suppose I have a class that is associated with another class. It will look something like this:

public class DisposableClassOne : IDisposable
{
   private class mDisposableClassTwo;

   public DisplosableClassOne(DisposableClassTwo dcTwoInjected)
   {
      mDisposableClassTwo = dcTwoInjected;
   }

   public void Dispose()
   {
      // Should I dispose here? or make caller dispose of dcTwoInjected
      //mDisposableClassTwo.Dispose();
   }
}

Should I call a method Disposefor mDisposableClassTwoor should I get the calling user to process it like this?

using(DisposableClassTwo dcTwoInjected = new DisposableClassTwo())
using(DisposableClassOne dcOne = new DisposableClassOne(dcTwoInjected))
{
   // do stuff with dcOne
}

I think that calling the caller is the best way, but I think that by placing the call in the Dispose method, it guarantees that it will be called. Is there a better way to handle this?

The simplest answer is to have two users (), even if you go and do (and document!) That the second IDisposable will recycle the first.
