如何在还包含字母的字符串中增加一个数字? [英] How to increase a number in a string that also contains letters?

问题描述

我想对字符串中的数字执行算术运算.

I want to perform arithmetic operations on numbers in a string.

例如:SGJKR67 应该变成 SGJKR68.

另一个:NYSC34 应该变成 NYSC35.

Another one: NYSC34 should become NYSC35.

只有数字发生了变化，在本例中，两者都增加了 1.

Only numbers are changed, in this example both are increased by one.

推荐答案

使用正则表达式和捕获组可以解决您的问题:

Using regex and Capturing Groups can solve your problem:

$reg = [regex]::new("([A-Z]+)(\d+)")
$m = $reg.Match("SGJKR67")
$digits = $m.Groups[2] # will be 67
$digits = $digit + 1; # or apply anything you want
$result = "$($m.Groups[1])$digits" # will be SGJKR and 68.

您的比赛将有 3 个小组:

You will have 3 groups for your matches:

• 整个词".
• 字母
• 数字.
