正则表达式的最小值和范围

I am trying to create a regex for a exactly five digit number which should be in the range between 90000 – 96163. I created a regex for exactly 5 number @"^\d{5}$" Now how do I make sure that it is between the range of 90000 – 96163? Anything smaller than 90001 and over 96162 should not work.

我正在尝试为正好五位数创建一个正则表达式，该数字应该在90000 - 96163之间。我创建了一个正则数为5的数字@“^ \ d {5} $”现在我如何确保它介于90000 - 96163之间？任何小于90001和超过96162的东西都不应该起作用。

Thanks

This is most easily achieved using a regular numeric comparison (using < and > operators) in your language.

使用您的语言使用常规数字比较（使用 <和> 运算符）最容易实现。

You can do a range check using regular expressions, but it's tedious to implement and all but nicely readable. For the sake of completeness, here's a possible pattern:

您可以使用正则表达式进行范围检查，但实现起来很繁琐，而且可读性很好。为了完整起见，这是一个可能的模式：

9([0-5][0-9]{3}|6(0[0-9]{2}|1([0-5][0-9]|6[0-3])))

Broken up, the pattern reads as follows:

分手了，模式如下：

9                       # The first digit must be a 9
(
    [0-5][0-9]{3}       # Covering the range 90000-95999
    |
    6                   # Matching 96xxx
    (
        0[0-9]{2}       # Covering the range 96000-96099
        |
        1               # Matching 961xx
        (
            [0-5][0-9]  # Covering the range 96100-96159
            |
            6[0-3]      # Covering the range 96160-96163
        )
    )
)

Please don't do this if it can be avoided. Just consider what happens when the range boundaries change: Imagine you have to check whether a value is between 7243 and 132843 — not fun.

如果可以避免，请不要这样做。只要考虑范围边界变化时会发生什么：想象一下，你必须检查一个值是否在7243和132843之间 - 不好玩。

Digit by digit:

数字：

/(?!^90000$)(^9([0-5]\d{3}|6(0\d{2}|1([0-5]\d|6[0-2]))))$/

#3

(9[0-5][0-9]{3}|960[0-9]{2}|961[0-5][0-9]|9616[0-3])

This would be enough to find a regex to find a range. No need to ask about range problems

这足以找到一个正则表达式来查找范围。无需询问范围问题
