how about the WTF?! design pattern?

seriously, a better pattern is DRY: why implement the aforementioned
classes when you could simply do, say, Int.Parse( text ) for a given
chunk of text inside a try block?

Because it provides encapsulation of parsing and validation. Instead
of having a giant switch statement (or something similar) the OP can
define the columns, and then just keep calling Parse etc. Sounds
reasonable to me.

Now, as for your suggestion: if you're going to try to parse something
and catch exceptions, the TryParse methods are better than calling
Parse inside a try block.
