How Can I Customize Json.NET Serialization in ASP.NET Web API?

Fine-Tuning Json.NET Serialization within ASP.NET Web API

ASP.NET Web API leverages Json.NET for efficient JSON serialization and deserialization. However, you can customize the default settings to suit specific application needs.

Adjusting JsonSerializerSettings

To modify the standard JsonSerializerSettings, access the Formatters.JsonFormatter.SerializerSettings property within the HttpConfiguration object.

For example, to generate nicely formatted JSON output with indentation:

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

This approach allows for granular control over JSON serialization. By directly manipulating the JsonSerializerSettings object, developers can incorporate type handling, date formatting, or any other desired settings, ensuring the JSON output precisely matches project specifications.
