How to cast a STRING to a GUID
<p>I need cast a String to a Guid.</p>

<p>I am using this code but</p>

<pre><code>string myUserIdContent = ((Label)row.FindControl("uxUserIdDisplayer")).Text;
Guid myGuidUserId = new Guid(myUserIdContent); // PROBLEM HERE
MembershipUser mySelectedUser = Membership.GetUser(myGuidUserId);
</code></pre>

<p>I receive this error</p>

<blockquote>
  <p>Exception Details: System.FormatException: Unrecognized
  Guid format.</p>
</blockquote>
