title: Stop implicit wildcard in Directory.GetFiles()
body: <pre><code>string[] fileEntries = Directory.GetFiles(pathName, "*.xml");
  </code></pre>
  
  <p>Also returns files like <code>foo.xml_</code>  Is there a way to force it to not do so, or will I have to write code to filter the return results.</p>
  
  <p>This is the same behavior as <code>dir *.xml</code> on the command prompt, but different than searching for <code>*.xml</code> in windows explorer.</p>
