title: SharePoint: Can I see the content of a document in the ItemAdding() event handler?
body: <p>I'd like to inspect the content of a file before it is uploaded to the SharePoint doc library.<br>
  I hooked up a handler to the <code>ItemAdding()</code> event but don't know how to get the content of the file.<br>
  Note: I know that in the <code>ItemAdded()</code> I can use <code>properties.ListItem.File</code> but that's too late.  </p>
  
  <p>Thanks in advance.</p>
