title: Pick random char
body: <p>i have some chars:</p>
  
  <pre><code>chars = "$%#@!*abcdefghijklmnopqrstuvwxyz1234567890?;:ABCDEFGHIJKLMNOPQRSTUVWXYZ^&amp;".ToCharArray();
  </code></pre>
  
  <p>now i'm looking for a method to return a random char from these.</p>
  
  <p>I found a code which maybe can be usefull:</p>
  
  <pre><code>static Random random = new Random();
          public static char GetLetter()
          {
              // This method returns a random lowercase letter
              // ... Between 'a' and 'z' inclusize.
              int num = random.Next(0, 26); // Zero to 25
              char let = (char)('a' + num);
              return let;
          }
  </code></pre>
  
  <p>this code returns me a random char form the alphabet but only returns me lower case letters</p>
