title: Regex match if a string has length 2 and contains 1 letter and 1 number
body: <p>Guys I hate Regex and I suck at writing.</p>
  
  <p>I have a string that is space separated and contains several codes that I need to pull out.  Each code is marked by beginning with a capital letter and ending with a number.  The code is only two digits.</p>
  
  <p>I'm trying to create an array of strings from the initial string and I can't get the regular expression right.</p>
  
  <p>Here is what I have</p>
  
  <pre><code>String[] test = Regex.Split(originalText, "([a-zA-Z0-9]{2})");
  </code></pre>
  
  <p>I also tried:</p>
  
  <pre><code>String[] test = Regex.Split(originalText, "([A-Z]{1}[0-9]{1})");
  </code></pre>
  
  <p>I don't have any experience with Regex as I try to avoid writing them whenever possible.  </p>
  
  <p>Anyone have any suggestions?</p>
  
  <p>Example input:</p>
  
  <p>AA2410 F7 A4 Y7 B7 A 0715 0836 E0.M80</p>
  
  <p>I need to pull out F7, A4, B7.  E0 should be ignored.</p>
