.net - String.Split VS. Regex.Split?

Question

If I have a delimited text file with a basic delimiter (say | for instance) does it make a difference whether I use a String or a Regex split?

Would I see any performance gains with one versus the other?

I am assuming you would want to use Regex.Split if you have escaped delimiters that you don't want to split on (| for example).

Are there any other reasons to use Regex.Split vs String.Split?

Answer 1

Regex.Split is more capable, but for an arrangement with basic delimitting (using a character that will not exist anywhere else in the string), the String.Split function is much easier to work with.

As far as performance goes, you would have to create a test and try it out. But, don't pre-optimize, unless you know that this function will be the bottleneck for some essential process.
