反序列化iso 8601日期(Deserialize iso 8601 date)

反序列化iso 8601日期(Deserialize iso 8601 date)

我有一个课程如下：

public class ViewItem { [DataMember(Name = "title")] public string Title { get; set; } [DataMember(Name = "created_at")] public string CreatedAt { get; set; } }

当我尝试将json字符串反序列化为object时，我永远无法获得CreatedAt字段的值。 我的json字符串如下：

[ { "created_at" : "2014-03-05T10:26:12Z" , "title" : "task 4" } , { "created_at" : "2014-03-05T10:26:12Z" , "title" : "task 5" } ]

反序列化代码如下：

JsonConvert.DeserializeObject<List<ViewItem>>(json);

我已经阅读了这篇文章，并尝试提供不同的json转换以及日期解析处理，但它不起作用。

更新：

我已经尝试过CreatedAt属性作为DateTime，DateTime？ 和DateTimeOffset以及简单的字符串。

I have a class as following:

public class ViewItem { [DataMember(Name = "title")] public string Title { get; set; } [DataMember(Name = "created_at")] public string CreatedAt { get; set; } }

When I try to deserialize json string to object, I never get value for CreatedAt field. My json string is as follows:

[ { "created_at" : "2014-03-05T10:26:12Z" , "title" : "task 4" } , { "created_at" : "2014-03-05T10:26:12Z" , "title" : "task 5" } ]

The deserialization code is as follows:

JsonConvert.DeserializeObject<List<ViewItem>>(json);

I have read this article and tried to supply different json convert as well date parse handling but it did not work.

Update:

I have tried CreatedAt property as DateTime, DateTime? and DateTimeOffset as well as simple string.

最满意答案

尝试将[DataContract]添加到类声明中。 还要将CreatedAt属性的类型从string更改为DateTime ：

[DataContract] public class ViewItem { [DataMember(Name = "title")] public string Title { get; set; } [DataMember(Name = "created_at")] public DateTime CreatedAt { get; set; } }

通过这些更改（以及对JSON的修复），它适用于我：

string json = @"[{""created_at"":""2014-03-05T10:26:12Z"",""title"":""task 4""},{""created_at"":""2014-03-05T10:26:12Z"",""title"":""task 5""}]"; List<ViewItem> list = JsonConvert.DeserializeObject<List<ViewItem>>(json); foreach (ViewItem item in list) { Console.WriteLine("Title: " + item.Title); Console.WriteLine("CreatedAt: " + item.CreatedAt); }

输出：

Title: task 4 CreatedAt: 3/5/2014 10:26:12 AM Title: task 5 CreatedAt: 3/5/2014 10:26:12 AM

Try adding [DataContract] to your class declaration. Also change the type of the CreatedAt property from string to DateTime:

[DataContract] public class ViewItem { [DataMember(Name = "title")] public string Title { get; set; } [DataMember(Name = "created_at")] public DateTime CreatedAt { get; set; } }

With these changes (and the fix to the JSON), it works for me:

string json = @"[{""created_at"":""2014-03-05T10:26:12Z"",""title"":""task 4""},{""created_at"":""2014-03-05T10:26:12Z"",""title"":""task 5""}]"; List<ViewItem> list = JsonConvert.DeserializeObject<List<ViewItem>>(json); foreach (ViewItem item in list) { Console.WriteLine("Title: " + item.Title); Console.WriteLine("CreatedAt: " + item.CreatedAt); }

Output:

Title: task 4 CreatedAt: 3/5/2014 10:26:12 AM Title: task 5 CreatedAt: 3/5/2014 10:26:12 AM
