Controllers层

public JsonResult gClass()
        {
            List<ClassInfo> list = SqlConn.cList();
            return Json(list);
        }

数据层

public static List<ClassInfo> cList()
        {
            List<ClassInfo> list = new List<ClassInfo>();
            ClassInfo cinfo;
            for (int i = 0; i < 10; i++)
            {
                cinfo = new ClassInfo();
                cinfo.ID = i;
                cinfo.Name = "UserName" + i;
                cinfo.set = true;
                cinfo.Address = "北京市" + i;
                list.Add(cinfo);
            }
            return list;
        }
