The Home of .NET's fastest JSON, JSV and CSV Text Serializers.

ServiceStack.Text is an independent, dependency-free serialization library that contains all of ServiceStack's text processing functionality, including:

JsonSerializer
TypeSerializer (JSV-Format)
CsvSerializer
T.Dump extension method
StringExtensions - Xml/Json/Csv/Url encoding, BaseConvert, Rot13, Hex escape, etc.
Stream, Reflection, List, DateTime, etc extensions and utils

Supports custom builds for: .NET 3.5+, Mono, MonoTouch/MonoDroid, Silverlight 4/5, XBOX, Windows Phone 7

All in a single 144kb dependency-free ServiceStack.Text.dll

        public override string ToString()
