title: What C# regex expression can be used to strip out dots (.) in a string?
body: <p>I need a string with non alpha-numeric characters etc stripped out of it; I used the following:</p>
  
  <pre><code>wordsstr = Regex.Replace(wordsstr, "[^A-Za-z0-9,-_]", "");
  </code></pre>
  
  <p>The problem being dots (.)s are left in the string yet they are not specified to be kept. How could I make sure dots are gotten rid of too?</p>
  
  <p>Many thanks.</p>
