Overview of this book

If you're writing applications that move structured data from one place to another, this book is for you. This is especially true if you've been using XML to do the job because it's entirely possible that you could do much of the same work with less code and less data overhead in JSON. While the book's chapters make some distinction between the client and server sides of an application, it doesn't matter if you're a frontend, backend, or full-stack developer. The principles behind using JSON apply to both the client and the server, and in fact, developers who understand both sides of the equation generally craft the best applications.

How to handle date and time objects using Json.NET


Dates in JSON are problematic for people because JavaScript's dates are in milliseconds from the epoch, which are generally unreadable to people. Different JSON parsers handle this differently; Json.NET has a nice IsoDateTimeConverter that formats the date and time in ISO format, making it human-readable for debugging or parsing on platforms other than JavaScript. You can extend this method to converting any kind of formatted data in JSON attributes, too, by creating new converter objects and using the converter object to convert from one value type to another.

How to do it…

Simply include a new IsoDateTimeConverter object when you call JsonConvert.Serialize, like this:

string json = JsonConvert.SerializeObject(p, 
newIsoDateTimeConverter());

How it works…

This causes the serializer to invoke the IsoDateTimeConverter instance with any instance of date and time objects, returning ISO strings like this in your JSON:
