Question

我从Web服务中找到了以下JSON对象

{
   "room":{
      "name":"Thunderdome",
      "created_at":"2012/04/15 00:36:27 +0000",
      "id":xxxxxxx,
      "users":[
         {
            "type":"Member",
            "avatar_url":"url",
            "created_at":"2012/02/27 14:11:57 +0000",
            "id":1139474,
            "email_address":"xxx@xxxxxxx.com",
            "admin":false,
            "name":"xxxx xxxxx"
         },
         {
            "type":"Member",

等

我正在使用以下行反序列化：

var room = JsonConvert.DeserializeObject<SingleRoom>(text);

以下映射类

public class SingleRoom
{
    public Room Room { get; set; }
}

[DataContract]
public class Room
{
    [DataMember]
    public int Id { get; set; }
    [DataMember]
    public string Name { get; set; }
    public string Image {
        get { return "Assets/campfire.png"; }
    }
    [DataMember]
    public string Topic { get; set; }
    [DataMember(Name ="membership_limit")]
    public int MembershipLimit { get; set; }
    [DataMember]
    public bool Full { get; set; }
    [DataMember]
    public bool Locked { get; set; }
    [DataMember(Name = "open_to_guests")]
    public bool OpenToGuests { get; set; }
    [DataMember(Name = "updated_at")]
    public DateTime UpdatedAt { get; set; }
    [DataMember(Name = "created_at")]
    public DateTime CreatedAt { get; set; }

    [DataMember(Name = "active_token_value")]
    public string ActiveTokenValue { get; set; }

     [DataMember(Name = "Users")]
    public List<User> Users { get; set; } 
}

[DataContract]
public class User
{
    [DataMember]
    public int Id { get; set; }
    [DataMember]
    public string Name { get; set; }

    [DataMember(Name = "email_address")]
    public string EmailAddress { get; set; }
    [DataMember]
    public bool Admin { get; set; }
    [DataMember]
    public DateTime CreatedAt { get; set; }
    [DataMember]
    public string Type { get; set; }

    [DataMember(Name = "avatar_url")]
    public string AvatarUrl { get; set; }
}

'Room'对象正确反序列化，但Room上的Users属性始终为null。我知道null结果是JSON.NET序列化无法找到匹配属性的结果。但是，我觉得我说得对吗？列表应与用户匹配。我知道JSON中的数组对象用户没有命名子项，是不是问题？如果是这样，我该如何解决？

谢谢！

这可行....你可以重命名它们（或使用JsonProperty属性）来使用c＃样式属性名称

（顺便说一句：Json.Net不需要DataMember，DataContract属性）

var obj = JsonConvert.DeserializeObject<SingleRoom>(json)

public class User
{
    public string type { get; set; }
    public string avatar_url { get; set; }
    public string email_address { get; set; }
    public bool admin { get; set; }
    public string name { get; set; }
    public string created_at { get; set; }
    public int id { get; set; }
}

public class Room
{
    public string topic { get; set; }
    public int membership_limit { get; set; }
    public bool locked { get; set; }
    public string name { get; set; }
    public List<User> users { get; set; }
    public bool full { get; set; }
    public bool open_to_guests { get; set; }
    public string updated_at { get; set; }
    public string created_at { get; set; }
    public int id { get; set; }
}

public class SingleRoom
{
    public Room room { get; set; }
}
