Bagaimana untuk Menyelesaikan Ralat JsonConvert.DeserializeObject Apabila Menyahseri JSON ke dalam Kelas C# POCO?

<code class="language-c#">public class User
{
    public string Username { get; set; }
    public string Name { get; set; }
    public string Location { get; set; }
    // ...
    [JsonProperty("accounts")]
    public List<Account> Accounts { get; set; }
}</code>

<code class="language-c#">public class User
{
    // ...
    [JsonProperty("accounts")]
    public Account Accounts { get; set; }
}</code>

<code class="language-c#">public class User
{
    [JsonProperty("username")]
    public string Username { get; set; }

    [JsonProperty("name")]
    public string Name { get; set; }

    [JsonProperty("location")]
    public string Location { get; set; }
    // ...
    [JsonProperty("accounts")]
    public Account Accounts { get; set; }
}</code>

<code class="language-c#">public class Account
{
    [JsonProperty("github")]
    public string Github { get; set; }
}</code>

<code class="language-c#">public class Badge
{
    [JsonProperty("name")]
    public string Name { get; set; }

    [JsonProperty("description")]
    public string Description { get; set; }

    // ...
}</code>

<code class="language-c#">using Newtonsoft.Json;
using System.Net;

class Program
{
    static User LoadUserFromJson(string response)
    {
        var user = JsonConvert.DeserializeObject<User>(response);
        return user;
    }

    static void Main()
    {
        using (WebClient wc = new WebClient())
        {
            var json = wc.DownloadString("http://coderwall.com/mdeiters.json");
            var user = LoadUserFromJson(json);
        }
    }
}</code>
