错误在解析JSON响应

Question

我有下面这段代码会从一个API调用的JSON响应。

我已经连载它，我试图使用LINQ获取特定的父节点，并通过网络搜索查找特定的文本。

HttpClient client = new HttpClient(); 
client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json")); 
HttpResponseMessage response = client.GetAsync(some url).Result; 
string strJson = response.Content.ReadAsStringAsync().Result; 
object jObj = (JObject)JsonConvert.DeserializeObject(strJson); 
Assert.IsTrue(response.IsSuccessStatusCode.Equals(true)); 
var a = JArray.Parse(jObj.ToString()); 
var Cast = a.SelectMany(x => x["episodes"]); 

我得到一个错误：

Object is not Json Array

的我怎么能做到这一点任何想法？

Answer 1

试试这个：而不是

JObject jObj = (JObject)JsonConvert.DeserializeObject(strJson); 
Assert.IsTrue(response.IsSuccessStatusCode.Equals(true)); 
var a = (JArray)jObj["cast"]; 

：

object jObj = (JObject)JsonConvert.DeserializeObject(strJson); 
Assert.IsTrue(response.IsSuccessStatusCode.Equals(true)); 
var a = JArray.Parse(jObj.ToString()); 

它已经反序列化，所以没有必要再分析它。

ACCES的a阵列进一步，例如：

foreach (var actor in a) 
{ 
    Console.WriteLine(actor["character"]); 
}

或者您可以使用动态功能：

dynamic jObj = JsonConvert.DeserializeObject(strJson); 
var a = jObj.cast;
