C# Class Extensions.JSON

This class encodes and decodes JSON strings. Spec. details, see http://www.json.org/ JSON uses Arrays and Objects. These correspond here to the datatypes ArrayList and Hashtable. All numbers are parsed to doubles. Pulled from http://techblog.procurios.nl/k/618/news/view/14605/14863/How-do-I-write-my-own-parser-for-JSON.html

Public Methods

Method	Description
JsonDecode ( string json ) : object	Parses the string json into a value
JsonDecode ( string json, bool &success ) : object	Parses the string json into a value; and fills 'success' with the successfullness of the parse.
JsonDecodeConfig ( string configFile ) : object
JsonDecodeFromFile ( string file ) : object
JsonDecodeFromVar ( string file ) : object	Decodes a JSON string stored in a text file. Assumes the string is defined as a JS variable.
JsonEncode ( object json ) : string	Converts a Hashtable / ArrayList object into a JSON string
