title: .Net Regex to match exactly one word
body: <p>I was wondering if this is even possible but I have:</p>
  
  <pre><code>Input:
  ABC Construction
  
  Database to Match:
  ABC
  ABC Linen
  ABC Noodle
  ABC Telecom
  ABC Sports
  </code></pre>
  
  <p>Is there a way to write a regex to match ABC Construction to ABC ONLY, and none of the other choices?</p>
  
  <p>I've tried </p>
  
  <blockquote>
    <p>^([\w+?]\b){1}</p>
  </blockquote>
  
  <p>and it's returning all 5 matches</p>
