Hi, I'm in the process of learning c#, but i'm getting the hang of it pretty 
fast.  The problem is documentation.  I've read up on C# reflection, and i'm 
already using it, but there are certain things which aren't stated.  For 
instance, my issue is that of class references.  How do you do such in C#. 
Like for instance, delphi:

{* class reference declaration *}
TDBObjectClass = class of TDBObject;

{*
    Method returns the remotable object for a given
   class type...the method here is a class funciton
*}
TDBObject.GetRemotableClass(aClass: TDBObjectClass):TRemotable;
begin
   .....
end;


My issue is how do i declare TDBObjectClass in C#?

Unless you write your own metaclasses, C# does not support class references 
per se. So the answer is, you can't declare class references without writing 
metaclasses yourself.

The nearest thing available is to use the System.Type class and create
instances using reflection (Activator.CreateInstance)

If you contact me by email, I have some C# source code to share. This code 
show how to handle metaclass with C#.
