如何在ASP.NET Web API中为Json.NET设置自定义JsonSerializerSettings? [英] How to set custom JsonSerializerSettings for Json.NET in ASP.NET Web API?

问题描述

我了解ASP.NET Web API本身使用Json.NET来(反序列化)对象，但是有没有一种方法可以指定要使用的JsonSerializerSettings对象呢?

I understand that ASP.NET Web API natively uses Json.NET for (de)serializing objects, but is there a way to specify a JsonSerializerSettings object that you want for it to use?

例如，如果我想在序列化的JSON字符串中包含type信息，该怎么办?通常，我会将设置注入到.Serialize()调用中，但是Web API会静默地执行该操作.我找不到手动注入设置的方法.

For example, what if I wanted to include type information into the serialized JSON string? Normally I'd inject settings into the .Serialize() call, but Web API does that silently. I can't find a way to inject settings manually.

推荐答案

您可以使用HttpConfiguration对象中的Formatters.JsonFormatter.SerializerSettings属性来自定义JsonSerializerSettings.

You can customize the JsonSerializerSettings by using the Formatters.JsonFormatter.SerializerSettings property in the HttpConfiguration object.

例如，您可以在Application_Start()方法中做到这一点:

For example, you could do that in the Application_Start() method:

protected void Application_Start()
{
    HttpConfiguration config = GlobalConfiguration.Configuration;
    config.Formatters.JsonFormatter.SerializerSettings.Formatting =
        Newtonsoft.Json.Formatting.Indented;
}
