To use or not to use regular expressions?

Question

I just asked this question about using a regular expression to allow numbers between -90.0 and +90.0. I got some answers on how to implement the regular expression, but mos

Answer 1

I would say that regex expressions are most effective on Strings. For other data types, manipulations of that data type will usually be more intuitive and provide better results.

For example, if you know that you're dealing with DateTime, then you can use the Parse and TryParse methods will the different formats and it will usually be more reliable than your own regex expressions.

In your example, you are dealing with numbers so deal with them accordingly.

Regex is very powerful, but it isn't the easiest code to read and to debug. When another reliable solution is at hand, you should probably go for that.
