MemoryStream.Close() or MemoryStream.Dispose()

Question

Which one do I call?

Is it necessary to call both?

Will the other throw an exception if I have already called one of them?

Answer 1

the following code is Stream.Dispose from reflector as you can see, you don't need to close if you dispose (which is implicit when using using)

public void Dispose()
{
    this.Close();
}
