title: Check if file exists not knowing the extension
body: <p>Is there an easy way to check if a file exists?  I know the name of the file just not the extension.</p>
  
  <p>The name of the file will always be their userID from the table.</p>
  
  <p>So for me I could be 1.*</p>
  
  <p>Anything from .jpg, .jpeg, .gif. .png etc for image formats.</p>
  
  <p>Is this easy or should I upload the file extension to the database?</p>
  
  <pre><code>if (System.IO.File.Exists("~/ProfilePictures/" + userID " + ".*"))
     {
     }
  </code></pre>
