关于转成JSON格式输出的问题

这样红括号中的格式 怎么怎么生产啊 这是小弟的  var New = from a in dataContext.org
                      from b in dataContext.org
                       where a.PKOrgID.ToString() == orgid && a.ParentID == "0"
                       && b.ParentID == orgid
                       select new
                       {
                           OrgName = a.OrgName,
                           MasterName = a.MasterName,
                          BranchName = b.OrgName,
                           Mobile = a.Mobile,
                           TelPhone = a.Telephone,
                           Fax = a.Fax,
                           Email = a.Email,

                       };
LINQ查询数据代码。还望大神给点指导~ 分不多。。别介意~

你确定是 "a":"1,2,3,4" ，而不是 "a":["1","2","3","4"] 或者 "a":[1,2,3,4] ？？
