[dba-VB] C# - what does this mean

I think they are talking about calling close in an overridden Finalize
method on a class.  That would only be if you implement your own
dispose/finalize methods in a class.  

You do want to close the reader and all if you are just using ado.net to
connect to and read from a SQL/OLEdb connection.

Closing the DataReader

You should always call the Close method when you have finished using the
DataReader object.

If your Command contains output parameters or return values, they will not
be available until the 
DataReader is closed.

Note that while a DataReader is open, the Connection is in use exclusively
by that DataReader. You 
will not be able to execute any commands for the Connection, including
creating another DataReader, 
until the original DataReader is closed.

     Note   Do not call Close or Dispose on a Connection, a DataReader, or
any other managed object 
in the Finalize method of your class. In a finalizer, only release unmanaged
resources that your 
class owns directly. If your class does not own any unmanaged resources, do
not include a Finalize 
method in your class definition. For more information, see Programming for
Garbage Collection.


NOTICE the Note above.  Why would you NOT call close at the very least.  I
understand Dispose - that 
is the garbage collector's job to do that when it decides it needs to but
close?
