Regex problem in vb.net

Question

I'm trying to create a regex that will matches with

"8-9."

but won't matches with

"8-9........"

I tried lots of possibilities yet, but still can't find the right one.

Answer 1

try

Dim r As Regex = New Regex("8\-9")
'Look for match
Dim m As Match = r.Match(mystring)

also might use

Dim r As Regex = New Regex("^8\-9$")

if you want a single word

Answer 2

Without a better worded question, ^8-9$ should do it..
