如何在MVC 4 Web API中为Json.NET设置自定义JsonSerializerSettings？

您可以

JsonSerializerSettings

Formatters.JsonFormatter.SerializerSettings

HttpConfiguration

例如，您可以在Application_Start（）方法中执行此操作：

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