asp.net mvc c#中的Json序列化

Question

public ActionResult About()
{
List listStores = new List();
listStores = this.GetResults(“param”);
return Json(listStores, “Stores”, JsonRequestBehavior.AllowGet);
}

使用上面的代码，我可以得到以下结果：

[{"id":"1","name":"Store1","cust_name":"custname1","telephone":"1233455555",
  "email":"abc@ac.com","geo":{"latitude":"12.9876","longitude":"122.376237"}},
 {"id":"2","name":"Store2","cust_name":"custname2","telephone":"1556454",
"email":"nfnf@ac.com","geo":{"latitude":"12.9876","longitude":"122.376237"}},

我怎样才能得到以下格式的结果？结果开头需要商店。

{
"stores" : [
{"id":"1","name":"Store1","cust_name":"custname1","telephone":"1233455555",
     "email":"abc@ac.com",
     "geo":{"latitude":"12.9876","longitude":"122.376237"}},
{"id":"2","name":"Store2","cust_name":"custname2","telephone":"1556454",
     "email":"nfnf@ac.com","geo":{"latitude":"12.9876","longitude":"122.376237"
}} ] }

Answer 1

试试

return Json(new { stores = listStores }, JsonRequestBehavior.AllowGet);

在上述语句中，您正在创建一个具有名为“stores”的属性的新对象，然后使用列表中的项目数组填充该对象。

你也可以使用一个类，定义如下：

[DataContract]
public class StoreListJsonDTO
{
    [DataMember(Name = "stores")]
    public List Stores { get; set; }

    public StoreListJsonDTO(List storeList)
    {
        this.Stores = storeList;
    }
}

然后在你的代码中，你会这样做：

var result = new StoreListJsonDTO(listStores);
return Json(result, JsonRequestBehavior.AllowGet);
