title: How to change the font style of text
body: <p>How can I change the Font Style (regular, bold, etc) ?</p>
  
  <p>So far what I have is this:</p>
  
  <pre><code>if (listBox1.SelectedIndex == 3)
  {
     if (textBox1.Text == "regular")
     {
       //FontStyle regular = new FontStyle   !!!wrong one!!!
     }
  }
  </code></pre>
  
  <p>So what i need is that when I'd type "regular" in the textbox, the font style will change to regular. How do I do that?</p>
