Is there a library that validates strings

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;

Code:

---

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.

Code:

---

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

---

I don't really understand the question. What "types"? Are you saying that you want to find one of those values in some text? Try providing a FULL and CLEAR explanation of the problem.

Hi, I edited my post.

Are you sure of that, string: 353.93.15.1 - returns true certainly isn't doing what I expect as that most definitely isn't a valid IP address....

A lot of the other data types might need an explanation as well - exactly what is a GID or TOKEN supposed to look like?

Hi I don't know all of them yet but I pasted an example GID at https://gist.github.com/onurcan19772...9c375aa594618b

and some token:

Code:

---

e6c3778f-6361-4ed0-b126-f2cf8fca06db

If you are trying to work with .torrent files then a better understanding of the structure might be a starting point you might want to look at something like https://en.wikipedia.org/wiki/Torren...File_structure or http://www.bittorrent.org/beps/bep_0003.html

Wikipedia is banned in my country, I have general knowledge about torrenting, of course I'll need to learn more about it. Thanks for your reply.
