title: PadLeft doesn't work
body: <p>I'm trying to add a character many times before a string. AMAIK in C#, it's PadLeft.</p>
  
  <pre><code>string firstName = "Mary";
  firstName = firstName.PadLeft(3, '*'); // This should return ***Mary
  </code></pre>
  
  <p>But it doesn't work. Am I doing something wrong?</p>
