从文件名中删除最后5个字符 [英] Remove last 5 characters from filename

问题描述

您好，我正在寻找一种方法来重命名整个文件目录

order。目录中的文件具有不同的长度，但是所有

以_xxxx结尾x'代表从我保存的程序中随机生成的数字

。所以我需要找到一种方法，我可以快速删除文件名

中的下划线和最后4个数字，而无需更改任何其他内容。我不能设置文件的最大长度

因为文件名的总长度不同。如果程序可以

从目录中的每个文件中删除最后5个字符，那么

会很棒！


谢谢你你的时间和考虑。

Hi, I''m looking for a way to rename a whole directory of files in short
order. The files in the directory have different lengths, however all
of them end with _xxxx the x''s represent a randomly generated number
from a program that I saved from. So I need to find a way that I can
quickly remove the underscore and the last 4 numbers from the filename
without changing anything else. I can''t set a max length to the file
becuase the filename''s overall length varies. If the program could
remove these last 5 characters from every file in the directory that
would be awesome!

Thanks for your time and consideration.

推荐答案

你看过System.IO.DirectoryInfo和System.IO.FileInfo

类了吗？

未经测试：


\\\

进口System.IO

..

..

..

Dim astr（）As String = Directory.GetFiles（" C：\ Foo"）

For each as As String in astr

Dim FileName As String = Path.GetFileNameWithoutExtension（s）

FileName = Strings.Left（FileName，FileName.Length - 5）

FileName& ; ="。 &安培; Path.GetExtension（s）

重命名（s，Path.Combine（Path.GetDirectoryName（s），FileName））

下一个s

///

Imports System.IO

..
Dim astr() As String = Directory.GetFiles("C:\Foo")
For Each s As String In astr
Dim FileName As String = Path.GetFileNameWithoutExtension(s)
FileName = Strings.Left(FileName, FileName.Length - 5)
FileName &= "." & Path.GetExtension(s)
Rename(s, Path.Combine(Path.GetDirectoryName(s), FileName))
Next s
///

Brian，

我会使用System.IO.Path获取文件名本身（减少任何路径或

扩展名。）


然后我会使用String.SubString& String.LastIndexOf删除_xxxx。


最后我会使用System.IO.Path将文件名重新组合在一起......


类似于：


Dim fullPath As String =" C：\ My Documents \ MyFile_1234.text"

Dim fileName As String = Path.GetFileNameWithoutExtension （fullPath）

Dim extension As String = Path.GetExtension（fullPath）

fileName = fileName.Substring（0，fileName.LastIndexOf（" _" c））

fileName = Path.ChangeExtension（fileName，extension）

fullPath = Path.GetDirectoryName（fullPath）

fullPath = Path.Combine（fullPath，fileName ）

希望这有帮助

Brian,
I would use System.IO.Path to get at the filename itself (less any path or
extension).

Then I would use String.SubString & String.LastIndexOf to remove the _xxxx.

Finally I would use System.IO.Path to put the filename back together...

Something like:

Dim fullPath As String = "C:\My Documents\MyFile_1234.text"
Dim fileName As String = Path.GetFileNameWithoutExtension(fullPath)
Dim extension As String = Path.GetExtension(fullPath)
fileName = fileName.Substring(0, fileName.LastIndexOf("_"c))
fileName = Path.ChangeExtension(fileName, extension)
fullPath = Path.GetDirectoryName(fullPath)
fullPath = Path.Combine(fullPath, fileName)
Hope this helps
Jay
