How to Parse JSON in Windows 8 Metro Apps Without JSON.NET?

Parsing JSON without JSON.NET in Metro Apps

In the realm of Metro application development for Windows 8, the absence of the popular JSON.NET library can pose a challenge. This article explores alternative solutions for parsing JSON data in a Metro context.

Solution: Utilize System.Json Namespace

Modern versions of .NET include the System.Json namespace, introduced in .NET 4.5. This namespace provides a set of classes designed for parsing and manipulating JSON data. To access these classes, add a reference to the System.Runtime.Serialization assembly.

Parsing JSON with JsonValue.Parse()

The JsonValue.Parse() method is central to the parsing process. It takes JSON text as input and returns a JsonValue instance:

JsonValue value = JsonValue.Parse(@"{ ""name"":""Prince Charming"", ...");

Casting to JsonObject for Object Data

If the JSON text represents an object, you can cast the JsonValue to a JsonObject:

JsonObject result = value as JsonObject;

Accessing Object Properties

Once you have the JsonObject, you can access its properties as follows:

Console.WriteLine("Name .... {0}", (string)result["name"]);
Console.WriteLine("Artist .. {0}", (string)result["artist"]);
Console.WriteLine("Genre ... {0}", (string)result["genre"]);

Navigating the JSON Structure

The System.Json classes provide a straightforward and flexible way to navigate and access JSON data, similar to the approach used in System.Xml.Linq for XML. Utilizing this namespace allows you to parse and process JSON data effectively in your Metro applications, even without the JSON.NET library.
