Regular expression (getting number, C#)

Question

Please help me to write Regular expression on C# for getting Int64 value from string:

"NumberLong("634461051992965873")"

my string includes NumberLong part;

so as result must be 634461051992965873

Thank you!)))

you do not need a regular expression to do this, you just need to call Int64.parse on the string — luketorjussen, Jul 13 '11 at 09:18
Does the string to be parsed include that text called "NumberLong"? — leppie, Jul 13 '11 at 09:20
What can other strings look like? How about `NumberLong('634461051992965873')`, `NumberLong23("634461051992965873")`, `NumberLong("maybe 634461051992965873 24141242")`. — Kobi, Jul 13 '11 at 09:26

string Temp = "Hax00r L33t";
string Output = Regex.Replace(Temp, "[^0-9]", "");
long num = long.Parse(Output);

thank you! but it is not what I need))) I have string "NumberLong("634461051992965873")" and from this string I want to cut integer number;) – Edward83 Jul 13 '11 at 09:16
this should be Int64.Parse(text) – luketorjussen Jul 13 '11 at 09:17

@RiaD Ok, you reduced the length of the string. But in the OP's case, `int.Parse` won't work for reasons you should know. ;-) – Alex R. Jul 13 '11 at 09:17
@Alex R:, yes, you are right. @Edward83:http://stackoverflow.com/questions/844461/return-only-digits-0-9-from-a-string – RiaD Jul 13 '11 at 09:19

String txt = "634461051992965873";
int nbr;

if(Int64.TryParse(txt, out nbr)) {
    // text can be converted to Integer
}
