c＃无法反序列化嵌套的json字符串

Question

我正在尝试反序列化嵌套的json字符串

   public class recentlySearchedAdd
    {
        public recentlySearchedAdd()
        {
            searchedLocations = new List<recentlySearchedLoc>();
        }
        public string status { get; set; }
        public List<recentlySearchedLoc> searchedLocations { get; set; }
    }

    public class recentlySearchedLoc
    {
        public int id { get; set; }
        public string location { get; set; }

    }

这是处理json字符串

的代码

        //dummy json string
        string json = "{\"status\": \"OK\", \"searchedLocations\": [{\"id\": 7, \"location\": \"California\"}, {\"id\": 4, \"location\": \"90007\"}, {\"id\": 3, \"location\": \"New York, NY\"}]}";
        JavaScriptSerializer ser = new JavaScriptSerializer();
        List<recentlySearchedAdd> recentlySearchedAddList = ser.Deserialize<List<recentlySearchedAdd>>(json);
        Response.Write("count:"+recentlySearchedAddList.Count);

计数为0 ......此代码有什么问题

你很亲密。序列化程序返回的是recentlySearchedAdd而不是它的列表。

JavaScriptSerializer ser = new JavaScriptSerializer();
recentlySearchedAdd recentlySearchedAddList = ser.Deserialize<recentlySearchedAdd>(json);
Console.Write("count:" + recentlySearchedAddList.searchedLocations.Count);
