I need regex for asp.net application to match an alphanumeric string at least 6 characters long.
Solução
I’m not familiar with ASP.NET. But the regular expression should look like this:
^[a-zA-Z0-9]{6,}$
^
and $
denote the begin and end of the string respectively; [a-zA-Z0-9]
describes one single alphanumeric character and {6,}
allows six or more repetitions.
Outras dicas
I would use this:
^[\p{L}\p{N}]{6,}$
This matches Unicode letters (\p{L}
) and numbers (\p{N}
), so it's not limited to common letters the Latin alphabet.
^\w{6,}$
^[a-zA-Z0-9]{6,}$
(Depending on the Regex implementation)
Note, that \w
also matches _
!
