的WebAPI Json.NET定制的日期处理 [英] WebApi Json.NET custom date handling

问题描述

我已经在全球范围明确配置我MVC4应用使用JSON.NET序列化。我知道我有序列化日期时，使用ISO标准的日期或旧的Microsoft日期格式的选择。

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.

但我怎么能输出自己的自定义DateTime格式字符串，如：DD / MM / YYYY HH：MM。

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

我可以在MVC3堵Json.NET作为默认的序列化时，这样做，但不能似乎做它在MVC4。

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我做：

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;

和定制转换器我试图impliment是像这样：

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"));
        }
    }

Anyhelp将AP preciated：）

Anyhelp would be appreciated :)

推荐答案

更改设置，设置code是这样的：

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code你只是改变局部变量的值。

In your code you are just changing local variable value.
