Próbuję uzyskać informacje z tej strony w c#

var client = new HttpClient();

string uri = "http://192.168....:..../getMem/...";

HttpClient httpClient = new HttpClient();
HttpRequestMessage request = new HttpRequestMessage();
request.RequestUri = new Uri(uri);
request.Method = HttpMethod.Post;

HttpResponseMessage response = httpClient.SendAsync(request).Result;
var responseString = response.Content.ReadAsStringAsync();

JObject joResponse = JObject.Parse(responseString.Result);
JObject ojObject = (JObject)joResponse["response"];
JArray array = (JArray)ojObject["dane"];

foreach (JObject item in array) // <-- Note that here we used JObject instead of usual JProperty
{
    Debug.WriteLine(item.ToString());
}

Ale linia JArray array ... zwraca błąd
