c# - JSON.NET 反序列化

Question

我有下一个 JSON 回调:

{
   "id":"1",
   "jsonrpc":"2.0",
   "result":{
   "articles":[
     {
        "date":1367582340000,
        "id":6917,
        "title":"Some Title",
        "author":"Name Surname",
        "event_date":1367584560000,
        "text":"blabla"            
     }
  ]
}
}

我想使用 JSON.NET 反序列化它

我写了下一段代码:

    class News
    {
        private string jsonrpc;
        private string id;
        private Result result;

        [JsonProperty("jsonrpc")]
        public string Jsonrpc
        {
            get { return jsonrpc; }
            set { jsonrpc = value; }
        }

        [JsonProperty("id")]
        public string Id
        {
            get { return id; }
            set { id = value; }
        }

        [JsonProperty("result")]
        public Result Result
        {
            get { return result; }
            set { result = value; }
        }
    }
    public class Result
    {
        public List<Article> articles;
        [JsonProperty("articles")]
        public List<Article> Articles
        {
            get { return articles; }
            set { articles = value; }
        }
    }
    public class Article
    {
        public string text;
        public int id;
        public int date;
        public string title;
        public string author;
        public string imageURL;
        [JsonProperty("text")]
        public string Text
        {
            get { return text; }
            set { text = value; }
        }
        [JsonProperty("id")]
        public int Id
        {
            get { return id; }
            set { id = value; }
        }
        [JsonProperty("date")]
        public int Date
        {
            get { return date; }
            set { date = value; }
        }
        [JsonProperty("title")]
        public string Title
        {
            get { return title; }
            set { title = value; }
        }
        [JsonProperty("author")]
        public string Author
        {
            get { return author; }
            set { author = value; }
        }
        [JsonProperty("imageURL")]
        public string ImageURL
        {
            get { return imageURL; }
            set { imageURL = value; }
        }
    }

用法:

 string JSON = reader.ReadToEnd();
 News ent = JsonConvert.DeserializeObject<News>(JSON) as News;

错误落下:

Newtonsoft.Json.DLL 中发生了类型为“Newtonsoft.Json.JsonSerializationException”的异常，但未在用户代码中处理

问题是什么？

Answer 1

A member with the name 'articles' already exists on 'Result'. Use the JsonPropertyAttribute to specify another name.

将 articles 字段设置为 private:

private List<Article> articles;

A member with the name 'text' already exists on 'Article'. Use the JsonPropertyAttribute to specify another name.

还是一样:

private string text;
private int id;
private int date;
private string title;
private string author;
private string imageURL;

或更好 - 使用自动实现的属性并丢弃字段，即

[JsonProperty("text")]
public string Text {get;set;}

Arithmetic operation resulted in an overflow.

将Date设为long:

[JsonProperty("date")]
public long Date {get;set;}

这是我之后的整个工作类(class):

class News
{
    [JsonProperty("jsonrpc")]
    public string Jsonrpc {get;set;}
    [JsonProperty("id")]
    public string Id { get; set; }
    [JsonProperty("result")]
    public Result Result { get; set; }
}
public class Result
{
    private List<Article> articles = new List<Article>();
    [JsonProperty("articles")]
    public List<Article> Articles { get { return articles; }}
}
public class Article
{
    [JsonProperty("text")]
    public string Text {get;set;}
    [JsonProperty("id")]
    public int Id {get;set;}
    [JsonProperty("date")]
    public long Date {get;set;}
    [JsonProperty("title")]
    public string Title {get;set;}
    [JsonProperty("author")]
    public string Author { get; set; }
    [JsonProperty("imageURL")]
    public string ImageURL { get; set; }
}

请注意，如果您只是反序列化，您甚至不需要 JsonProperty - 因为除了大小写之外，名称都是相同的，只有当您也在序列化.
