Question

I’m trying to split a string that can either be comma, space or semi-colon delimitted. It could also contain a space or spaces after each delimitter. For example

22222,11111,23232 
OR
22222, 11111, 23232 
OR
22222;     11111; 23232
OR
22222 11111 23232 

Any one of these would produce an array with three values ["22222","11111","23232"]

So far I have var values = Regex.Split("22222, 11111, 23232", @"[\\s,;]+") but this produces an array with the second and third values including the space(s) like so:

["22222"," 11111"," 23232"]

You have two possibilities:

• Regex.Split
• String.Split

In this case, you want to split your string by specific delimiters caracters. String.Split has been created for this special purpose. This method will be faster than Regex.Split.

char[] delimiters = new [] { ',', ';', ' ' };  // List of your delimiters
var splittedArray = myString.Split(delimiters, StringSplitOptions.RemoveEmptyEntries);
