protected override void RenderWebPart(HtmlTextWriter output)
        {
            Guid guid = AreaManager.GetSystemAreaGuid(PortalContext.Current,SystemArea.News);
            Area area = AreaManager.GetArea(PortalContext.Current,guid);
            AreaCollection areas = area.Areas;
            
            ArrayList al = new ArrayList();
            for(uint i=0;i<areas.Count;i++)
            {
                al.Add(areas[i]);
            }
            al.Sort(new AreaComparer());
            output.RenderBeginTag(HtmlTextWriterTag.Table);
            for(int i=0;i<al.Count;i++)
            {
                output.RenderBeginTag(HtmlTextWriterTag.Tr);
                output.RenderBeginTag(HtmlTextWriterTag.Td);
                output.Write(((Area)al[i]).Title+((Area)al[i]).Order);
                output.RenderEndTag();
                output.RenderEndTag();
            }
            output.RenderEndTag();
        }

        public class AreaComparer : IComparer
        {
            public int Compare(Object x, Object y)
            {
                if(((Area)x).Order < ((Area)y).Order)
                {
                    return -1;
                }
                return 1;
            }

        }

Remarks

The caller must have PortalRight.ViewArea and PortalRight.ViewPages permissions to perform this operation.
