Basically you can't, all .NET components work the same way.

I don't believe I can't access the "(Name)" property by code within the
component class.
I will ask on MS newsgroups...

Sure, you could also check the help file, there is no name property
for any .net component. The property editor makes this up based purely
on the name of the variable it is assigned to in the initialization
(hence the parentheses around the name).

OK, I've found where this property is located.
Actually it is a property of the ISite interface which is available thru 
Component.Site property.
The Site property has a value only when the component is dropped on a form 
(owned by a container). So to use that property, you can write the code 
below:

    [Browsable(false)]
    public string Name {
        get { if (Site == null)
                  return FName;
              else
                  return Site.Name;
            }
        set { FName = value;
              if (Site != null)
                  Site.Name = FName;
            }
    }
    protected string FName;

This code define a non browsable property (that is which doesn't appears in 
the object inspector and is mapped to the Site.Name property when Site is 
assigned. If not, it is mapped to a protected string member.

This implementation perfectly fit my need: When a component is dropped on a 
form, it has a value for Site.Name which is available thru the Name property 
I created. When the component is created at runtime, it has a the property 
Name which is mapped to the adequate storage.

I could enhance a little bit the implementation by overriding set_Site in 
order to not loose the Name property value when the component is included 
within a container. But this is not necessary for any use I have.
