这是我的简单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; }
}
我用来将 JSON 响应反序列化为 User
对象的方法(这个实际的 JSON call is here ):
private User LoadUserFromJson(string response)
{
var outObject = JsonConvert.DeserializeObject<User>(response);
return outObject;
}
这会引发异常:
Cannot deserialize the current JSON object (e.g. {"name":"value"}) into type 'System.Collections.Generic.List`1[CoderwallDotNet.Api.Models.Account]' 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) 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. Path 'accounts.github', line 1, position 129.
以前从未使用过这种 DeserializeObject 方法,我有点卡在这里。
我已确保 POCO 类中的属性名称与 JSON 响应中的名称相同。
我可以尝试将 JSON 反序列化到这个 POCO 类中吗?
最佳答案
这是一个工作示例。
关键点是:
账户声明
JsonProperty
属性的使用
.
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>

}
public class Badge
{
[JsonProperty("name")]
public string Name;

public string Description;
[JsonProperty("created")]
public string Created;

public string BadgeUrl;
}
