The regex

[yxq]

I want to apply the regex below in vb.net
^([a-zA-Z]\:|\\\\[^\/\\:*?"<>|]+\\[^\/\\:*?"<>|]+)(\\[^\/\\:*?"<>|]+)+(\.[^\/\\:*?"<>|]+)$

The url
http://www.regexlib.com/REDetails.aspx?regexp_id=425

But vb.net said there are invalid chars.

Dim a As String = "m:\twxt\.exe"

'The code below invalid.....
Dim b As String =
"^([a-zA-Z]\:|\\\\[^\/\\:*?"<>|]+\\[^\/\\:*?"<>|]+)(\\[^\/\\:*?"<>|]+)+(\.[^\/\\:*?"<>|]+)$"

MessageBox.Show(Regex.IsMatch(a, b))


Thank you

Hi,

To add a " to a string use "". Try this for you regular expression
pattern string.

Dim b As String =
"^([a-zA-Z]\:|\\\\[^\/\\:*?""<>|]+\\[^\/\\:*?""<>|]+)(\\[^\/\\:*?""<>|]+)+(\.[^\/\\:*?""<>|]+)$"
