How Can I Parse JSON in Metro Applications Without JSON.NET?

Parsing JSON Without JSON.NET in Metro Applications

Metro applications developed within Visual Studio 2011 necessitate alternative methods for JSON parsing. This is because the well-known JSON.NET library has yet to incorporate support for Metro platforms.

To circumvent this limitation, developers can leverage the classes available within the System.Json namespace, which was introduced in .NET 4.5. After adding a reference to the System.Runtime.Serialization assembly, the following steps can be followed:

1. Parse JSON Text: Using the JsonValue.Parse() method, it is possible to parse JSON text and obtain a corresponding JsonValue:

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

2. Convert to JsonObject: If a JSON object is provided as input, the JsonValue can be cast to a JsonObject:

using System.Json;

JsonObject result = value as JsonObject;

3. Extract Property Values: Property values can be accessed by indexing the JsonObject using the desired property name:

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

These classes exhibit a similar structure to those found within the System.Xml.Linq namespace, making them relatively familiar for developers working in .NET.
