This class provides static (shared) helper methods. The UrlEncode( ) and UrlDecode( ) methods are the same as those provided by the HttpServerUtility class for encoding a string into a format that's safe for use in a URL. Additionally, a UrlEncodeToBytes( ) method is provided to convert a string into an array of bytes and a UrlEncodeUnicode( ) method to convert a string into a Unicode string.
