title: .NET GUID uppercase string format
body: <p>I need to format my GUIDs in the dashed format, all uppercase. I know using <code>myGuid.ToString("D")</code> or <code>String.Format("{0:D}", myGuid)</code> gives the dashed format, but using an uppercase <code>D</code> as opposed to a lower-case <code>d</code> doesn't give me an uppercased GUID like I thought it would. Is there a way to do this without doing anything crazy, or do I just need to call <code>myGuid.ToString().ToUpper()</code>?</p>
