[Firebird-net-provider] Invalid attempt of read when the reader is closed.

[<alb...@ti...>]

Hi,
  using a version 2.1.0 RC-1 i have 
  some problem with a Dispose 
method.

  Why throw this exception ?
   "Invalid attempt of read when 
the reader is closed."

  I create a FbCommand in this mode:

  private 
static object executeQuery(DbConnection p_conn, string p_sql, hashtable 
p_params)
 {
    DbCommand oc = null;
    object res = DBNull.Value;

    if (p_conn.getType().Equals(typeOf(FbConnection)) ){
       oc = 
new FbCommand(p_sql, (FbConnection)p_conn);
       ... assign params
       res = oc.ExecuteReader();    
          
    }
    ...other 
database connection type, such as Oracle, Sql Server...

    oc.
Dispose();    

    return res;
  }

  I use the Dispose() method 
because I see the memory of the
  main process increase in exponential 
mode.

Sorry for my bad english.

Thanks.

Alberto
