從動態{System.RuntimeType}變量解析json響應時出錯

我正在使用一些使用動態變量的代碼jsonResponse。從動態{System.RuntimeType}變量解析json響應時出錯

dynamic jsonResponse = JsonConvert.DeserializeObject(response);

此變量包含json格式的酒店列表的集合。從這個集合我得到roomlist集合在一個新的變量roomResponseList：

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

我得到的第一個房間的細節到** 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，當我試圖使用LINQ拉姆達得到JObject任何項目列表中，我得到的錯誤，「無法在Newtonsoft.Json.Linq.JProperty訪問孩子的價值。」

價值roomByResponse的=

變化的LINQ to

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