title: Increment a string with both letters and numbers
body: <p>I have a string which i need to increment by 1 The string has both characters and numeric values.</p>
  
  <p>The string layout i have is as follows "MD00494"</p>
  
  <p>How would i increment this to "MD00496" &amp; "MD00497" ect</p>
  
  <p>If it was a normal string with numbers i would parse it to an int. </p>
  
  <p>I have tried the following</p>
  
  <pre><code> int i = int.Parse(sdesptchNo);
   i++;
   txtDispatchNo.Text = i.ToString();
  </code></pre>
  
  <p>Anyone any ideas how i would go about this.</p>
