Get attachment icon for CMS File

We add files via the CMS Desk tree, as a CMS File item. We list them in a repeater using a custom transformation on the CMS.File document type.

However, we want to display the icon using the macro GetAttachmentIconUrl. Now I'm having trouble getting the extension for the file? How can I access it? Eval("AttachmentExtension") returns blank.

RE:Get attachment icon for CMS File

I wrote a custom transformation:

public string GetFileExtension(object attachmentGuid)
{
	AttachmentManager am = new AttachmentManager();
	DataSet ds = am.GetAttachments(string.Format("AttachmentGUID = '{0}'", attachmentGuid.ToString()), "AttachmentOrder", false);

	if (ds.Tables[0].Rows.Count > 0)
	{
		var attachment = am.GetAttachmentInfo(ds.Tables[0].Rows[0]["AttachmentGUID"].ToString(), CMSContext.Current.SiteName);
		return attachment.AttachmentExtension;
	}

	return "";
}

And then used it like this:

<img src="<%# GetAttachmentIconUrl(GetFileExtension(Eval("FileAttachment")), "List") %>" />
