Is there a library that validates strings

[nikel]

Hi, is there a library that checks against the types I stated above? It doesn't matter if it's C# C++ another library. These are data types used by a download manager / bittorrent client.

ADDR	INTERFACE	METALINK_FILE	PID	SIZE	VALUE
COMMAND	INTERFACES	METHOD	POLL	TAG	VERSION
DIGEST	IPADDRESS	METHOD	PORT	TOKEN	[=SIZE],tail[=SIZE]
DIR	IPADDRESS[,...]	MINUTES	PORT...	TORRENT_FILE	[true|false]
DSCP	KEYWORD	N	PROTO	TYPE	[true|false|A:B]
FILE	LANGUAGE	NUM	PROXY	TYPE	plain|arc4
GID	LENGTH	OPT	RATIO	URI	true|false
HEADER	LEVEL	OS	REFERER	URI[,...]	true|false|mem
HOST:PORT	LOCATION[,...]	PEER_AGENT	SEC	USER	*
INDEX...	LOG	PEER_ID_PREFIX	SELECTOR	USER_AGENT	*

EDIT: What I need is ex. if I want to validate against IPADDRESS these must return true;

string: 233.93.15.1 - returns true
string: 353.93.15.1 - returns true
string: 15.25       - returns false

if I want it to validate DIR this must happen.

string: C:\Program Files\7-Zip\      - returns true
string: D:\music\michael_jackson\ - returns true
string: D/mp3           - returns false
