Hello, I want to create regex, that will match numbers...
I've created this:

string str = myRegex; //let it for example be "[8-10]"
Regex isnumber = new Regex(str); /* when the number has 2 or more digits, then the exception is thrown here [x-y] range in reverse order */
matches = isnumber.IsMatch(9);
...
...

can you please tell me, how string in new Regex(str) should look like to be able match numbers from 0 to 999 ?

You can use the regex pattern... \d{1,3} which will match any number that has 1 to 3 digits... covering 0 to 999. (Note: Would also cover 000 just so you know)

The pattern above says a digit (the \d part aka specifier) which appears 1 to 3 times (the quantifier).

For some reason your link was all jacked up for me, so I figured I'd post it as CODE in case they had the same problem.

http://www.regular-expressions.info/numericranges.html

EDIT: seems this displays another bug, it displays fine until the actual [code] renders, it's doing the same thing in your link except that it replaces with safe-codes (lt; gt; etc).

The bug you mention regarding the word "expressions" is well-known.
