Question

我正在研究一些使用动态变量 jsonResponse 的代码。

dynamic jsonResponse = JsonConvert.DeserializeObject(response);

此变量包含json格式的酒店列表集合。我从这个集合中获得了一个新的变量 roomResponseList ：

var roomResponseList = jsonResponse["hotels"]["hotels"][rooms].roomResponseList;

我得到第一个房间细节到** JObject responseRateKeys **：

foreach (var roomByResponse in roomResponseList)
{
    JObject responseRateKeys = JObject.Parse(roomByResponse.ToString());
    var boardNameListByResponse = responseRateKeys.AsJEnumerable().AsEnumerable()
                                                   .Select(t => t["rates"]["boardName"].ToString().Trim())
                                                   .Distinct()
                                                   .ToList();
}

但是当我试图通过使用linq lambda从JObject获取任何项目列表时，我收到错误， “无法访问Newtonsoft.Json.Linq.JProperty上的子值。”

roomByResponse =

Answer 1

将linq更改为

responseRateKeys["rates"].AsJEnumerable().Select(t=>t["boardName"]).Distinct().ToList()

从动态{System.RuntimeType}变量解析json响应时获取错误
