XML Converstions in ASP.net

XmlDocument xDoc = (XmlDocument)JsonConvert.DeserializeXmlNode(EntityIDList);

            //string xNode = xDoc.OuterXml;

            if (EntityIDList != null && EntityIDList != "")

                ObjListBO.EntityIdList = xDoc.OuterXml.Replace("<RootXML>", "").Replace("</RootXML>", "");
