详解JsonResult的使用方法

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;

  }

protected void Page_Load(object sender, EventArgs e)

  {

   var customer = new customer { name = "李华", sex = "男" };

   var customer1 = new customer { name = "小芳", sex = "女" };

   var li = new List<customer>();

   li.Add(customer);

   li.Add(customer1);

   var list = Newtonsoft.Json.JavaScriptConvert.SerializeObject(li);

   var tt = "[{\"name\":\"李华\",\"sex\":\"男\"},{\"name\":\"小芳\",\"sex\":\"女\"}]";

   //new Newtonsoft.Json.JsonSerializer()..(customer);

   Response.Write(tt);

   Response.End();

  }

  public class customer

  {

   public string name { get; set; }

   public string sex { get; set; }

  }
