title: C# Convert Hexadecimal to string
body: <p>I think I'm having a little problem because I'm confusing my terminology on this. </p>
  
  <p>I need to wrap a string with a vertical tab (char)11 or (char)0x0b on the front and a (char)28 or (char)0x1c on the end.</p>
  
  <p>Part of my confusion is I don't understand what the difference between the 11 and the 0x0b is.  I believe one is ascii and one is hex, but I'm not positive.  So essentially I need to do</p>
  
  <pre><code>string response = (char)0x0b + "message" + (char)0x1c;
  </code></pre>
  
  <p>That doesn't seem to work though.</p>
