easyui datagrid Footer

场景：easyui datagrid footer解决方案

easyui datagrid footer
 var jsonStr = new
            {
                rows = from d in data
                       select new
                       {
                           d.ID,
                           d.NAME,
                           d.VALUE
                       },
                footer = new
                         {
                             NAME= "合计",
                             VALUE= 10
                         }
            };

生成的json格式"footer":{"NAME":"合计","VALUE":10} footer没有加【】 正确格式应该是"footer":[{"NAME":"合计","VALUE":10} ]
怎么生成正确格式
