For lack of better words, I would like to make an enum of strings. There are several masks for text boxes that I would like to standardize in our system.

For simplicity lets say there are 2 masks:
"PhoneNumber" which is "(999)000-0000"
"Zip Code" which is "00000-9999"

I would like to be able to reference these through out the entire program in a manner such as:

DefaultMasks.ZipCode or DefaultMasks.PhoneNumber

Since enums can not be of string type, what would your best suggestions be as to how I could do this.

I had thought about a class with constants in it but I was not sure how to implement that properly.

Thanks in advance for any help,

RH
