 ## Remarks  
  Because most of the methods provided by the <xref:System.Data.DataTableReader> class must be provided with an ordinal column number, you can use the `GetOrdinal` method to retrieve the column number, given the name of the column.  
   
- `GetOrdinal` performs a case-sensitive lookup first. If it fails, a second case-insensitive search is made. If the column number is not found an `IndexOutOfRangeException` is thrown.
