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;
跌倒错误:
Newtonsoft.Json.DLL中出现“Newtonsoft.Json.JsonSerializationException”类型的异常,但未在用户代码中处理
有什么问题?
答案 0 :(得分:2)
“结果”中已存在名称为“文章”的成员。使用JsonPropertyAttribute指定另一个名称。
制作articles
字段private
:
private List<Article> articles;
再次相同:'Article'上已存在名为'text'的成员。使用JsonPropertyAttribute指定另一个名称。
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;}
算术运算导致溢出。
让Date
成为long
:
[JsonProperty("date")]
public long Date {get;set;}
以后是我的整个工作班:
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,则甚至不需要JsonProperty
- 因为除了大小写以外,名称都是相同的,所以只有在您序列化的情况下才有意义
