Match 0 to 60 in regular expression

Question

What is the regular expression to match the numbers 0 through 60? No negative numbers allowed and no decimals.

Answer 1

Like this: ^([0-5]?[0-9]|60)$

In C#:

int temp;
if (int.TryParse(str, out temp) && temp >= 0 && temp <= 60)

Answer 2

假设Perl兼容正则表达式，并且没有前导零

/([1-5]?[0-9]|60)/
