详解mvc使用JsonResult返回Json数据_实用技巧_

 public JsonResult UpdateSingle(int id, string actionName, string actionValue) { var res = new JsonResult(); //var value = "actionValue"; //db.ContextOptions.ProxyCreationEnabled = false; var list = (from a in db.Articles select new { name = a.ArtTitle, yy = a.ArtPublishTime }).Take(5); //记得这里要select new 否则会报错：序列化类型 System.Data.Entity.DynamicProxies XXXXX 的对象时检测到循环引用。 //不select new 也行的加上这句 //db.ContextOptions.ProxyCreationEnabled = false; res.Data = list;//返回列表 var name = "小华"; var age = "12"; var name1 = "小华"; var age1 = "12"; res.Data = new object[] { new { name, age }, new { name1, age1 } };//返回一个自定义的object数组 var person = new { Name = "小明", Age = 22, Sex = "男" }; res.Data = person;//返回单个对象； res.Data = "这是个字符串";//返回一个字符串,意义不大； res.JsonRequestBehavior = JsonRequestBehavior.AllowGet;//允许使用GET方式获取，否则用GET获取是会报错。 return res; }
