Array with string index - Visual Basic .NET

John

Hi

Is there a way to create an array of strings of subscript of type index too?
Like;

x("Element A")="Value for element A"

Thanks

Others have suggested System.Collecti ons.Hashtable, but I would like to
throw out, System.Collecti ons.Specialized .StringDictiona ry.

It's typesafe. It only takes strings as keys and only takes strings as
values. Hashtable takes object, so you have to do a lot of casting :)

John,
In addition to HashTable & StringDictionar y, there are:

System.Collecti ons.DictionaryB ase - for creating your own type safe
dictionaries (hash tables)

System.Collecti ons.Specialized .NameObjectColl ectionBase - for creating your
own type safe that are keyed by Strings & indexed.

System.Collecti ons.Specialized .NameValueColle ction which is similar to
StringDictionar y, however also supports being indexed by an integer...

Basically check out the various collections in both System.Collecti ons &
System.Collecti ons.Specialized .

Hope this helps
Jay
