Regular expression that should not allow loading of exe file format

Question

I have this file upload control that downloads all kinds of files. I have to limit it so that it does not allow exe formats. Can anyone help me on this. I cannot enter valid file formats, as this is unpredictable .. I need to limit only the exe format. promotion

Answer 1

You can use regex:

^(?!.*\.exe$).*$

Answer 2

This regular expression will match a line starting with any character ('^. *') And ending with ".exe" ('\ .exe $'):

^(.*\.exe)$
