asked on

Regular expression required to validate a FileUpload path.

Why is the following validation expression for my RegularExpressionValidator failing on my jpg upload?

     ValidationExpression="^(([a-zA-Z]:)|(\\{2}\w+)\$?)(\\(\w[\w].*))+(.jpg|.jpeg|.gif|.bmp|.png)$"

See:
       http://msdn2.microsoft.com/en-us/library/aa479405.aspx.

I changed the example shown and modified it to allow on image files.
It may be because I have incorrectly interpreted when converting expression to a single line expression from:

   ValidationExpression="^(([a-zA-Z]:)|(\\{2}\w+)\$?)(\\(\w[\w].*))
    +(.mp3|.MP3|.mpeg|.MPEG|.m3u|.M3U)$"



Any help appreciated.

Hi smacca,

Easiest way to find out...change the example into one line...does it still work? Then you did something else wrong, doesn't work? (which would be my first guess) then the + is probably the one causing you a headache..

Regards,
Max.

try this:

string fRegex = "^.+\.((jpg)|(gif)|(jpeg))$";

ValidationExpression="^([a-zA-Z]\:|\\)\\([^\\]+\\)*[^\/:*?'<;>;|]+\.(jpg|jpeg|gif|bmp|png)(l)?$"

The following validation expression is not working:

ValidationExpression="^(([a-zA-Z]:)|(\\{2}\w+)\$?)(\\(\w[\w].*))(.jpg|.jpeg|.JPG|.JPEG)$"
