Remarks

Because the DataTableReader always returns the type stored within the underlying DataColumn, the value returned by calling the GetProviderSpecificFieldType method always returns the same type as the type stored within the DataTable. When you work with the DataTableReader class, calling the GetProviderSpecificFieldType method returns the same type as calling the GetType method.
