SharePoint 读取 Site Columns 的数据并绑定到DropdownList

 public void GetSiteColumns(DropDownList ddl, String siteColumn)

         {

             var fields = new SPSite(ProjectContent.SiteUrlMapping).RootWeb.Fields;

             var projectCodeXml = fields.TryGetFieldByStaticName(siteColumn).SchemaXml;

             XmlDocument xmlDoc = new XmlDocument();

             xmlDoc.LoadXml(projectCodeXml);

             XmlNode xn = xmlDoc.SelectSingleNode("Field/CHOICES");

             foreach (var xnl in xn)

             {

                 XmlElement xe = (XmlElement)xnl;

                 ddl.Items.Add(xe.InnerText);

             }

         }
