While Deserialize the json string from the api "https://jsonplaceholder.typicode.com/posts" - json-deserialization

Question

I'm experiencing An unhandled exception of type 'Newtonsoft.Json.JsonSerializationException' occurred in Newtonsoft.Json.dll Additional information: Cannot deserialize the current JSON array (e.g. [1,2,3]) into type 'ConsoleApplication3.Program+UserData' because the type requires a JSON object (e.g. {"name":"value"}) to deserialize correctly..
{
class Program
{
public class UserData
{
public int userId { get; set; }
public int id { get; set; }
public string title { get; set; }
public string body { get; set; }
}
static void Main(string[] args)
{
string url = #"https://jsonplaceholder.typicode.com/posts";
WebRequest request = WebRequest.Create(url);
WebResponse response = request.GetResponse();
Stream data = response.GetResponseStream();
StreamReader reader = new StreamReader(data);
// json-formatted string from api
var responseFromServer = reader.ReadToEnd();
UserData udata = JsonConvert.DeserializeObject<UserData>(responseFromServer);//getting error connot deserialize
}
}
}

I guess what you need is ...
change
UserData udata = JsonConvert.DeserializeObject<UserData>(responseFromServer);
to UserData udata = JsonConvert.DeserializeObject<List<UserData>>(responseFromServer);
Notice <UserData> vs List<UserData>, that is the only variation.
Could you please try this?

Adding code and rextester - http://rextester.com/IRUB82213
Code:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text.RegularExpressions;
using Newtonsoft.Json;
namespace Rextester
{
public class Program
{
public static void Main(string[] args)
{
string responseFromServer = #"
[{
'userId': 1,
'id': 1,
'title': 'sunt aut facere repellat provident occaecati excepturi optio reprehenderit',
'body': 'quia et suscipit\nsuscipit recusandae consequuntur expedita et cum\nreprehenderit molestiae ut ut quas totam\nnostrum rerum est autem sunt rem eveniet architecto'
},
{
'userId': 1,
'id': 2,
'title': 'qui est esse',
'body': 'est rerum tempore vitae\nsequi sint nihil reprehenderit dolor beatae ea dolores neque\nfugiat blanditiis voluptate porro vel nihil molestiae ut reiciendis\nqui aperiam non debitis possimus qui neque nisi nulla'
}]";
var usersData = JsonConvert.DeserializeObject<List<UserData>>(responseFromServer);
foreach(var userData in usersData){
Console.WriteLine(userData.id);
}
}
public class UserData
{
public int userId { get; set; }
public int id { get; set; }
public string title { get; set; }
public string body { get; set; }
}
}
}
