title: Minimum Length Regular Expression
body: <p>I'm trying to write a regular expression that will validate that user input is greater than X number of non-whitespace characters.  I'm basically trying to filter out begining and ending whitespace while still ensuring that the input is greater than X characters; the characters can be anything, just not whitespace (space, tab, return, newline).
  This the regex I've been using, but it doesn't work:</p>
  
  <pre><code>\s.{10}.*\s
  </code></pre>
  
  <p>I'm using C# 4.0  (Asp.net Regular Expression Validator) btw if that matters.</p>
