Json.NET

Json.NET is a popular high-performance JSON framework for .NET

Features

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.

The JSON serializer is a good choice when the JSON you are reading or writing maps closely to a .NET class.

LINQ to JSON is good for situations where you are only interested in getting values from JSON, you don't have a class to serialize or deserialize to, or the JSON is radically different from your class and you need to manually read and write from your objects.

Download Json.NET from CodePlex or install using NuGet

Json.NET is a personal open source project. Started in 2006, I have put hundreds of hours adding, refining and tuning Json.NET with the goal to make it not just the best JSON serializer for .NET but the best serializer for any computer language. I need your help to achieve this.

Is there a offline document? I cannot access json.net in China, because your website is blocked by Chinese Greatwall Firewall.

Json.NET

Json.NET is a popular high-performance JSON framework for .NET

Features

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.

The JSON serializer is a good choice when the JSON you are reading or writing maps closely to a .NET class.

Download Json.NET from CodePlex or install using NuGet
