vb.net中的正则表达式问题

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

如果没有措辞更好的问题， ^8-9$应该这样做。

Answer 2

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
