title: Remove leading Characters and starting from Numeric
body: <p>I want to remove leading string part of "<strong>PO Box 323</strong>" Kind of string.
  I just need to pick 323 for save.How to do that?</p>
  
  <p><strong>Note:</strong> After first occurrence of numeric can have characters.That is not a problem.
  By using sub string only cannot do this.Any idea ?</p>
  
  <p><strong>UPDATE :</strong> This is the Final Solution :</p>
  
  <pre><code>provider.Address.Street = Regex.Match(update.Address.Street, @"\d+.[a-zA-Z\ \d\#]*").Value;
  </code></pre>
