c# - problem writing regular expression -

-

i trying write regular expression matches of following:

{string} {string[]} {string[6]}

where instead of 6 in last line, there positive integer. also, wherever string appears in above lines, there int.

here regular expression wrote : {(string|int)(([]|[[0-9]])?)}. worked wouldn't allow more 1 digit within square bracket. overcome problem, modified way : {(string|int)(([]|[[0-9]*])?)}.

the modified regex seems having serious problems. matches {string[][]}. can please tell me causes match against this? also, when try enclose [0-9] within paranthesis, exception saying "too many )'s". why happen?

can please tell me how write regular expression satisfy requirements?

note : tryingthis in c#

you need escape special characters {} , []:

\{(string|int)(\[\d*\])?\}

you might need use [0-9] instead of \d depending on engine use.
