c# - 使用JsonConvert.DeserializeObject将Json反序列化为C#POCO类

这是我简单的User POCO类:

/// <summary>
/// The User class represents a Coderwall User.
/// </summary>
public class User
{
    /// <summary>
    /// A User's username. eg: "sergiotapia, mrkibbles, matumbo"
    /// </summary>
    public string Username { get; set; }

    /// <summary>
    /// A User's name. eg: "Sergio Tapia, John Cosack, Lucy McMillan"
    /// </summary>
    public string Name { get; set; }

    /// <summary>
    /// A User's location. eh: "Bolivia, USA, France, Italy"
    /// </summary>
    public string Location { get; set; }

    public int Endorsements { get; set; } //Todo.
    public string Team { get; set; } //Todo.

    /// <summary>
    /// A collection of the User's linked accounts.
    /// </summary>
    public List<Account> Accounts { get; set; }

    /// <summary>
    /// A collection of the User's awarded badges.
    /// </summary>
    public List<Badge> Badges { get; set; }

}

以及用于将JSON响应反序列化为User对象(此实际JSON call is here)的方法:

private User LoadUserFromJson(string response)
{
    var outObject = JsonConvert.DeserializeObject<User>(response);
    return outObject;
}

这会引发异常:



以前从未使用过此DeserializeObject方法，我有点被困在这里。

我确保POCO类中的属性名称与JSON响应中的名称相同。

我如何尝试将JSON反序列化到此POCO类中？

最佳答案

这是一个工作示例。

关键点是:

Accounts的声明

使用JsonProperty属性

。

using (WebClient wc = new WebClient())
{
    var json = wc.DownloadString("http://coderwall.com/mdeiters.json");
    var user = JsonConvert.DeserializeObject<User>(json);
}

public class User
{
    /// <summary>
    /// A User's username. eg: "sergiotapia, mrkibbles, matumbo"
    /// </summary>
    [JsonProperty("username")]
    public string Username { get; set; }

    /// <summary>
    /// A User's name. eg: "Sergio Tapia, John Cosack, Lucy McMillan"
    /// </summary>
    [JsonProperty("name")]
    public string Name { get; set; }

    /// <summary>
    /// A User's location. eh: "Bolivia, USA, France, Italy"
    /// </summary>
    [JsonProperty("location")]
    public string Location { get; set; }

    [JsonProperty("endorsements")]
    public int Endorsements { get; set; } //Todo.

    [JsonProperty("team")]
    public string Team { get; set; } //Todo.

    /// <summary>
    /// A collection of the User's linked accounts.
    /// </summary>
    [JsonProperty("accounts")]
    public Account Accounts { get; set; }

    /// <summary>
    /// A collection of the User's awarded badges.
    /// </summary>
    [JsonProperty("badges")]
    public List<Badge> Badges { get; set; }
}

public class Account
{
    public string github;
}

public class Badge
{
    [JsonProperty("name")]
    public string Name;
    [JsonProperty("description")]
    public string Description;
    [JsonProperty("created")]
    public string Created;
    [JsonProperty("badge")]
    public string BadgeUrl;
}
