DataReader - hardcode ordinals?

Question

When returning data from a DataReader I would typically use the ordinal reference on the DataReader to grab the relevant column:

if         


        

Answer 1

The problem with ordinal is if the order of the columns change and you are forced to modify the consumer code for the DataReader, unlike using column names.

I dont think there is a performance gain when using ordinal or column names, it is more on best practice and coding standards and code maintainability really
