WebApi Json.NET 自定义日期处理 [英] WebApi Json.NET custom date handling

问题描述

我已全局显式配置我的 MVC4 应用程序以使用 JSON.NET 序列化程序.我知道在序列化日期时我可以选择使用 ISO 标准日期或旧的 Microsoft 日期格式.

I have globally explicitly configured my MVC4 app to use the JSON.NET serializer . I know i have the choice of using the ISO standard dates or the old Microsoft date format when serializing dates.

但是我如何输出我自己的自定义日期时间格式字符串，比如:dd/MM/yyyy hh:mm".

But how can i output my own custom dateTime format string ,like :"dd/MM/yyyy hh:mm".

在插入 Json.NET 作为默认序列化程序时，我可以在 MVC3 中执行此操作，但在 MVC4 中似乎无法执行此操作.

I could do this in MVC3 when plugging in Json.NET as the default serializer but cant seem to do it in MVC4 .

到目前为止在 application_start 中我已经完成了:

So far in the application_start i have done :

  var settings =     GlobalConfiguration.Configuration.Formatters.JsonFormatter.SerializerSettings;            
        JsonSerializerSettings jSettings = new Newtonsoft.Json.JsonSerializerSettings()
        {
            Formatting = Formatting.Indented,
            DateTimeZoneHandling = DateTimeZoneHandling.Utc,


        };
        jSettings.Converters.Add(new MyDateTimeConvertor() );
        settings = jSettings;

我试图实现的自定义转换器是这样的:

and the custom converter i tried to impliment is like so :

 public class MyDateTimeConvertor : DateTimeConverterBase
    {
        public override object ReadJson(JsonReader reader, Type objectType, object existingValue, JsonSerializer serializer)
        {
            return DateTime.Parse(reader.Value.ToString());
        }

        public override void WriteJson(JsonWriter writer, object value, JsonSerializer serializer)
        {
            writer.WriteValue(((DateTime)value).ToString("dd/MM/yyyy hh:mm"));
        }
    }

任何帮助将不胜感激:)

Anyhelp would be appreciated :)

推荐答案

像这样更改您的设置设置代码:

Change your setting set up code like this:

JsonMediaTypeFormatter jsonFormatter = GlobalConfiguration.Configuration.Formatters.JsonFormatter;
JsonSerializerSettings jSettings = new Newtonsoft.Json.JsonSerializerSettings()         
{
    Formatting = Formatting.Indented,
    DateTimeZoneHandling = DateTimeZoneHandling.Utc
};
jSettings.Converters.Add(new MyDateTimeConvertor());
jsonFormatter.SerializerSettings = jSettings;

在您的代码中，您只是在更改局部变量值.

In your code you are just changing local variable value.
