Hi

I have a list of value pairs as below;

Section Name Section Type
A1111 Z9999
B2222 Y8888
C3333 X7777

What is a good intuitive way to store this information in memory? I was
thinking a two-dimensional array of strings, is there a better way?

Thanks

Regards

Will you need to look up a value from a key? If so perhaps a hashtable?

Simplest way is with two parallel one-dimensional arrays.
Another way is as an array of structures.
I also liked Jeff's solution.
His question has merit - how will you be accessing the elements?

Generic Dictionary or a hashtable.

With hashtables and dictionary... it's a bit amateurish to use two
parallel arrays.

Hashtable("SectionName") = Type

A generic dictionary can store different data types too.

Or, you could create an array of custom objects which store SectionName
/ Section Type.
