String pairs (multidimensional array?) C#

Question

I basically want to keep a track of old filenames and each file's new filename.

I could use a Dictionary I suppose, but I want to keep it really lightweight.

Would a multidimensional string array work just as well?

Answer 1

Use the Dictionary<string,string> class:

1. It manages its own size for you
2. It uses hashes to speed up searching for elements
3. You can just go fileNames[oldName] to get the name instead of using a loop or LINQ

Really, the Dictionary is the lightweight solution here.
