如何在运行时划分字符串？ [英] How can I delimitate a string at runtime?

问题描述

我希望编写一个实用程序，使用正则表达式一次批量重命名一堆文件。我将一次重命名的文件遵循某个命名约定，我想使用已经在文件名中的数据将它们更改为新的命名约定;但并非我的所有文件目前都遵循相同的约定。



所以我希望能够编写一个通用程序，让我在运行时输入到文本框中的模式文件名，以及我想从文件名中提取的用于重命名的标记。



例如 - 假设我有一个这样命名的文件：



[Coalgirls] _Suite_Precure_02_（1280x720_Blu-Ray_FLAC）_ [33D74D55] .mkv



我希望能够将此文件重命名为：



Suite Precure - Ep 02 [Coalgirls] [33D74D55] .mkv



这意味着我最好能够在重命名类似

 [％group％] _ Suite_Precure_％ep％_（...）_ [％crc％]。mkv 并填充局部变量group，ep和crc以用于批量重命名。
 
 
 
我怎么可能接近这个？
解决方案
 
使用常规ex压力组：
 
 
 \ [（？< publisher>。*？）\] _Suite_Precure _（？< ep> \d +）_ \（ （小于？组>？*）\）_\ [（小于？CRC>？*）\] .MKV< / CRC>< /组>< / EP>< /出版者> ; 
这产生了4组，所以你的例子变成：
 
 
发布者CoalGirls 
 Ep 02 
 Group 12080x720_Blu-Ray_FLAC 
 CRC 33D74D55 
然后您可以在Regex.Replace中使用这些来生成新名称：
 
 
 
 
 
 {集团} _Suite_Precure _ 
 
 
 {EP} _（
 
 
I am looking to write a utility to batch rename a bunch of files at once using a regular expression. The files that I will be renaming all at once follow a certain naming convention, and I want to alter them to a new naming convention using data that''s already in the filenames; but not all my files follow the same convention currently.



So I want to be able to write a general use program that lets me input into a textbox during runtime the pattern of the filename, and what tokens I want to extract from the filename to use for renaming.



For example - Assume I have one file named as such:



    [Coalgirls]_Suite_Precure_02_(1280x720_Blu-Ray_FLAC)_[33D74D55].mkv



I want to be able to rename this file to:



    Suite Precure - Ep 02 [Coalgirls][33D74D55].mkv



This means I would preferably be able to enter into my program before renaming something akin to 
[%group%]_Suite_Precure_%ep%_(...)_[%crc%].mkv
 and it would populate the local variables "group", "ep", and "crc" to use in the batch rename.



How might I approach this?
解决方案
Use the Regular expression groups:

\[(?<publisher>.*?)\]_Suite_Precure_(?<ep>\d+)_\((?<group>.*?)\)_\[(?<crc>.*?)\].mkv</crc></group></ep></publisher>
This produces 4 groups, so your example becomes:

Publisher   CoalGirls
Ep          02
Group       12080x720_Blu-Ray_FLAC
CRC         33D74D55
You can then use these in the Regex.Replace to generate the new name:


{Group}_Suite_Precure_

{Ep}_(
