Hello what is the new way in Umbraco 7 to write out this method in a .cs file for a website that is being rendered in WebForms, that is attaching to a Document Type, called AccordionGroup in Umbraco -> Settings -> Document Types:

public static AccordionGroup ParseDocument(Document aDocument)
{
    AccordionGroup theAccordionGroup = new AccordionGroup();

    theAccordionGroup.ID = aDocument.Id; 

    if(aDocument.getProperty("headline") != null)
    {
        theAccordionGroup.Headline = aDocument.getProperty("headline").Value.ToString();
    }

    return theAccordionGroup;
}

public static Document ToDocument(XmlNode aXmlNode)
{
    int theID = 0;

    XmlNode theIDNode = aXmlNode.SelectSingleNode("ID");
    XmlNode theHeadlineNode = aXmlNode.SelectSingleNode("Headline");

    if (theIDNode != null) int.TryParse(theIDNode.InnerText, out theID);

    if (theID > 0)
    {
        Document theDocument = new Document(theID);

        theDocument.getProperty("headline").Value = theHeadlineNode == null ? "" : theHeadlineNode.InnerText;

        return theDocument;
    }
    return null;
}

Or is this no longer being used? Thanks!

Using the following namespaces:

using umbraco.NodeFactory;
using umbraco.cms.businesslogic.media;
using umbraco.cms.businesslogic.web;

Also, should I be using different namespaces? If so, which one?
