title: ASP.NET: Get Page's filename
body: <p>I have an ASPX page named <code>Default.aspx</code>. From its codebehind on <code>Page_Load()</code>, I would like to get "Default.aspx", alone, into a string:</p>
  
  <pre><code>protected void Page_Load(object sender, EventArgs e)
  {
      string aspxFileName = ?;
  }
  </code></pre>
  
  <p>What should I replace <code>?</code> with&mdash;what will get me the ASPX filename?</p>
