Question

I need a regex that will verify whether the input string is in format 5’6″ or not… thats all. i need to verify it in cs file (c#) not client side.

Answer 1

You could use a simple regular expression:

      string height="5'6\"";

      Regex r = new Regex("^\\d+'\\d+\"$");
      Match m = r.Match(height);
      if (m.Success)
      {
            ' Yes!
      }

The regular expression “^\\d+’\\d+\”$” laid out:

• ^ = start of string
• \d+ = one or more numbers
• ‘ = character ‘
• \d+ = one or more numbers
• \” = character “
• $ = end of string

Edit: Added mandatory .Net escaping of backslash within “”.
