How to match string formate in Regex c#
I am passing a correct string formate but its not return true.
string dimensionsString= "13.5 inches high x 11.42 inches wide x 16.26 inches deep";
// or 10.1 x 12.5 x 30.9 inches
// or 10.1 x 12.5 x 30.9 inches ; 3.2 pounds
Regex rgxFormat = new Regex(@"^([0-9.]+) ([a-z]+) x ([0-9.]+) ([a-z]+) x ([0-9.]+) ([a-z]+)( ; ([0-9.]+) ([a-z]+))?$");
if (rgxFormat.IsMatch(dimensionsString))
//match
I can't understand whats wrong with code ?
" ([a-z]+)"
@Wiktor Stribiżew there is 10.1 x 12.5 x 30.9 this pattern are fixed but, some time added string after number (2 word or more than 2 also possible).You suggestion is correct for 2 word string but if come more than ? like "13.5 inches high x 11.42 inches wide test x 16.26 inches deep";

Replace them with
(.*?). Try ^([0-9.]+) (.*?) x ([0-9.]+) (.*?) x ([0-9.]+) (.*?)( ; ([0-9.]+) (.*))?$, see this demo.– Wiktor Stribiżew

(.*?)
^([0-9.]+) (.*?) x ([0-9.]+) (.*?) x ([0-9.]+) (.*?)( ; ([0-9.]+) (.*))?$

Your pattern only accounts for single words after the numbers. Allow any number of symbols there to fix the pattern:
^([0-9.]+) (.*?) x ([0-9.]+) (.*?) x ([0-9.]+) (.*?)( ; ([0-9.]+) (.*))?$
See the regex demo.
Replace regular spaces with s to match any kind of whitespace if necessary.
s

Your regex does not match several words after the number. See regex101.com/r/q8XJIB/2 where I just doubled each
" ([a-z]+)". However, what are the pattern requirements? Is the number of words fixed?– Wiktor Stribiżew
