title: Regular expression match all numbers after the last dash?
body: <p>Trying to find the last instance of numbers after last dash in a string so</p>
  
  <p><code>test-123-2-456</code> would return <code>456</code></p>
  
  <p><code>123-test</code> would return <code>""</code></p>
  
  <p><code>123-test-456</code> would return <code>456</code></p>
  
  <p><code>123-test-456sdfsdf</code> would return <code>456</code></p>
  
  <p><code>123-test-asd456</code> would return <code>456</code></p>
  
  <p>The expression, <code>@"[^-]*$"</code>, does not match the numbers though, and I have tried using [\d] but to no avail.</p>
