Encodes a byte array into its equivalent string representation using base 64 digits, which is usable for transmission on the URL.
The string containing the encoded token if the byte array length is greater than one; otherwise, an empty string ("").
The HttpServerUtility.UrlTokenEncode(Byte[]) method converts a byte array into an equivalent string representation encoded with base 64 digits. The resulting string token can be transmitted on the URL.
The HttpServerUtility.UrlTokenEncode(Byte[]) will return an empty string if the input parameter has a length of less than one.
