title: generating GUID without hyphen
body: <p>I am generating a GUID using the following statement in my code</p>
  
  <pre><code>byte[ ] keyBytes = Encoding.UTF8.GetBytes( Guid.NewGuid( ).ToString( ).Substring( 0, 12 ) );
  </code></pre>
  
  <p>But, when a GUID is generated, I find that it contains the hyphen character too. How do I go about in generating a GUID with only letters (upper case and lower case) and numbers? I do not want the hyphen. Can someone give me so idea?</p>
