使用Directory.GetFiles与正则表达式状滤波器 [英] Using Directory.GetFiles with regex-like filter

问题描述

我有两个文件的文件夹：

• Awesome.File.20091031_123002.txt


• Awesome.File.Summary.20091031_123152.txt

此外，第三方应用程序处理文件内容如下：

• 读取一个 FOLDERPATH 和是searchPattern 从数据库中


• 执行 Directory.GetFiles（FOLDERPATH，是searchPattern），处理任何文件匹配散装过滤器，然后移动文件存档文件夹。

事实证明，我有我的两个文件移动到不同的存档文件夹，所以我需要处理它们分别由提供不同searchPatterns逐一选择。请注意，我不能修改的第三方应用程序，但我可以修改我的数据库中是searchPattern和文件的目的地。

什么是searchPattern 将让我选择 Awesome.File.20091031_123002.txt 不包括 Awesome.File.Summary.20091031_123152 .TXT ？

解决方案

Awesome.File。 ???????? _ ??????。TXT

问号（？）作为一个单一的字符占位符。

I have a folder with two files:

• Awesome.File.20091031_123002.txt
• Awesome.File.Summary.20091031_123152.txt

Additionally, a third-party app handles the files as follows:

• Reads a folderPath and a searchPattern out of a database
• Executes Directory.GetFiles(folderPath, searchPattern), processing whatever files match the filter in bulk, then moving the files to an archive folder.

It turns out that I have to move my two files into different archive folders, so I need to handle them separately by providing different searchPatterns to select them individually. Please note that I can't modify the third-party app, but I can modify the searchPattern and file destinations in my database.

What searchPattern will allow me to select Awesome.File.20091031_123002.txt without including Awesome.File.Summary.20091031_123152.txt?

解决方案

Awesome.File.????????_??????.txt

The question mark (?) acts as a single character place holder.
