.NET CF 2.0: Stream implements IDisposable ... sort of?

I ran into something strange in a .NET CF 2.0 for Pocket PC 2003 (Visual Studio 2005) project. I dealt with the object System.IO.Stream

and found that the IDE would not auto-populate the method Dispose()

. I typed it in manually and got:

'System.IO.Stream.Dispose (bool)' not available due to protection level

The error belongs to the protected method Dispose(bool)

. Dispose()

is personal or not.

Question 1: How is this possible? Stream

implements IDisposable

:

public abstract class Stream : MarshalByRefObject, IDisposable

      

        
        
        
      

    

... and IDisposable

a method is required Dispose()

:

public interface IDisposable
{
    void Dispose();
}

      

        
        
        
      

    

I know the compiler won't let me get away with my code.

Question 2: Can I cause problems by running and locating my streams directly?

IDisposable idisp = someStream;
idisp.Dispose();

      

        
        
        
      

    

Implicit selection is accepted by the compiler.

Edit: This was already mentioned in question 939124 . The class Stream

explicitly implements IDisposable

. This is a language feature that I completely forgot about.
