Parsing Json String

Question

Is there a native library that would allow me to parse a Json formatted string? Say, for example, I had the string:

string inp = "{ \"title\": \"My Title\" }";

Is there a class where I can construct an object using that Json formatted string and find the value for title?

Edit: My app is a console application.

What kind of C# application? Certain projects (like MVC) have libraries available to handle this, otherwise you're looking at using another third-party one. -- e.g. JavaScriptSerializer — Brad Christie

I am trying to find one that can be used from a Console app. — TheDude

@BradChristie: You can generally use most libraries from most environments. — Eric J.

@TheDude: Both alternatives in my answer work with a console app. — Eric J.

@Eric: although you can, I generally wouldn't find myself including an MVC library in a WCF project just to use one object or feature. — Brad Christie

You can use the DataContractJsonSerializer to deserialize a Json formatted string into an object

http://msdn.microsoft.com/en-us/library/bb410770.aspx

For better performance, if you're willing to install a NuGet package,

http://json.codeplex.com/

is quite popular.

Both alternatives work for a console application.

DataContractJsonSerializer is what I am looking for!

DataContractJsonSerializer has many issues. Even Microsoft seems to be using Json.Net lately. Watch out for DCJS issues with DateTimes.

Not a native but a powerful one: Json.NET

Flexible JSON serializer for converting between .NET objects and JSON
LINQ to JSON for manually reading and writing JSON
High performance, faster than .NET's built-in JSON serializers
Write indented, easy to read JSON
Convert JSON to and from XML
Supports .NET 2, .NET 3.5, .NET 4, Silverlight, Windows Phone and Windows 8.

There is a native solution now in .NET. I agree though that Json.NET is generally superior.

@EricJ. I also prefer Json.NET, way more flexible.

Depending on the type of project, JavaScriptSerializer may be available. Also allows you to create parsers that can populate custom objects.
