title: Match text outside Parentheses
body: <p>I have a string</p>
  
  <pre><code>string s = Hello, (L05-#301ME) I am a programmer.
  </code></pre>
  
  <p>I need to extract this to</p>
  
  <pre><code>string result = Hello, I am a programmer
  </code></pre>
  
  <p>That mean I need to get all text ouside the parentheses. How can I use RegEx to do this task</p>
