VB.Net Regular expression

Question

I want to have a string in the following format

"FAG001 FAG002 FAG003"

and want to split it into

"FAG001" "FAG002" "FAG003"

using a regular expression. Unfortunately my knowledge of regular expression synatax is limited to say teh least. I have tried things like

Dim result = Regex.Split(npcCodes, "([A-Z]3[0-9]3)").ToList

without luck

Answer 1

No need of regex here, you could use String.Split

Dim result As String() = npcCodes.Split(new Char[]{" "})

But if you really want to use regex :

Dim result = Regex.Split(npcCodes, " ").ToList()

Answer 2

The regular expression to use in the Split method would be really simple:

Dim result = Regex.Split(npcCodes, " ").ToList

As the expression only matches a single character, you can just as well use the regular Split method in the String class:

Dim result = npcCodes.Split(" "C).ToList

Answer 3

As madgnome has pointed out you don't need regular expressions here if the string is always separated with spaces.

However for your information the error you made was that you need curly braces for numeric quantifiers:

[A-Z]{3}

And instead of Regex.Split you can uses Regex.Matches.
