title: RegularExpressionValidator on ASP.NET
body: <p>I know that there is a built in validation control on asp.net that can be use to validate internet email address. </p>
  
  <p>The code is:</p>
  
  <pre><code>&lt;asp:RegularExpressionValidator ID="RegularExpressionValidator1" runat="server" 
          ErrorMessage="RegularExpressionValidator" 
          ValidationExpression="\w+([-+.']\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*"&gt;&lt;/asp:RegularExpressionValidator&gt;
  </code></pre>
  
  <p>I know it is created by Microsoft but I want to know if this is the best to use regex for validating email address.</p>
  
  <p>Thanks in advance!</p>
