{
public string Name { get; set; }
public string Addr1 { get; set; }
public string Addr2 { get; set; }
}
public async void GET(string url)
{
//string result = string.Empty;
HttpWebRequest httpWebRequest = (HttpWebRequest)WebRequest.Create(url);
httpWebRequest.Method = "Get";
StreamReader reader;
try
{
HttpClient client = new HttpClient();
client.BaseAddress = new Uri(url);
client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
HttpResponseMessage response = client.GetAsync("https://csi10a.erpsl.inforcloudsuite.com/IDORequestService/ido/load/ue_GDL_CustAddrs").Result;
if (response.IsSuccessStatusCode)
{
IEnumerable < ue_GDL_CustAddrs > Addr = response.Content.ReadAsAsync<IEnumerable<ue_GDL_CustAddrs>>().Result;
foreach (var p in Addr)
{
Console.WriteLine("{0}\t{1};\t{2}", p.Name, p.Addr1, p.Addr2);
Console.ReadLine();
}
}
else
{
Console.WriteLine("{0} ({1})", (int)response.StatusCode, response.ReasonPhrase);
}
}
catch (WebException ex)
{
WebResponse errorResponse = ex.Response;
using (Stream responseStream = errorResponse.GetResponseStream())
{
reader = new StreamReader(responseStream, System.Text.Encoding.GetEncoding("utf-8"));
String errorText = reader.ReadToEnd();
}
throw;
}
}

i have send the url through main method but got an exception

 

One or more errors occurred. (Cannot deserialize the current JSON object (e.g. {"name":"value"}) into type 'System.Collections.Generic.IEnumerable`1[Englert_Ewarranty_QAD_Integration_Details.ue_GDL_CustAddrs]' because the type requires a JSON array (e.g. [1,2,3]) to deserialize correctly.

 

To fix this error either change the JSON to a JSON array (e.g. [1,2,3]) or change the deserialized type so that it is a normal .NET type (e.g. not a primitive type like integer, not a collection type like an array or List<T>) that can be deserialized from a JSON object. JsonObjectAttribute can also be added to the type to force it to deserialize from a JSON object.
