I require a regular Expression to validate FileName in C# that ignores everything except all upper/lower alpha chars, numbers, backslash, underscore, period, dash, etc. "*" and "?" for wildcards. I want to use that in RegEx.IsMatch(fileName,expression)

  • Be aware that invalid filenames exist that are made up entirely of valid characters, like `NUL` or `COM1` etc... – Tim Pietzcker Nov 01 '13 at 10:32
  • You really should at least give learning regular expressions a go. It is extremely easy when you start at the beginning. – Gusdor Nov 01 '13 at 10:32

    @Ravi And what's wrong with it? You should have an idea how an expression for what you want could look like so try create one your self. – Ondrej Janacek Nov 01 '13 at 10:32
