问题
While trying to extract zip files I get the error:
c:\path\name.zip is not RAR archive
No files to extract
My code is:
p.StartInfo.FileName = @"C:\Program Files\WinRAR\rar.exe";
p.StartInfo.Arguments = string.Format("x -o- {2} \"{0}\" * \"{1}\"\\ ",
szFN,
outFolder,
passWord == null ? "" : string.Format("-p\"{0}\"", passWord));
The GUI version can extract zip and 7z files.
Why doesn't this work? How can I extract zip and 7z files?
(NOTE: I have different source code for 7zip. I guess I can merge the two and only use the above when the file has a rar extension. But I don't like that solution.)
回答1:
Free unrar.exe
and console versionRar.exe
of WinRAR support only RAR archive format. That is clearly described in second paragraph in manual for Rar.exe
which is the text file Rar.txt
in program files folder of WinRAR.
You need to use WinRar.exe
instead which supports also other archive formats:
[path\winrar.exe] x [switches] [path to zip file] [files to extract, . for all files] [path folder to extract to]
Example:
"%ProgramFiles%\WinRAR\winrar.exe" x -ibck c:\file.zip *.* c:\folder\
The syntax, commands and switches for GUI version WinRAR.exe
are listed and described in help of WinRAR. Click in menu Help on menu item Help topics, open on help tab Contents the item Command line mode and read the help pages listed under this item.
For example the switch -ibck
supported only by WinRAR.exe
but not by Rar.exe
is for running the extraction in background which means GUI version of WinRAR makes the extraction minimized to an icon in Windows system tray.
回答2:
rar.exe
can indeed only unpack rar files. It's not at all the same as WinRAR.
For unpacking ZIP files in .NET, you might want to look at the DotNetZip library instead. It has a license compatible with commercial software, unlike CSharpZipLib.
If you need to support RAR as well, you can use UnRAR.dll with pinvoke:

http://www.rarlab.com/rar/UnRARDLL.exe
Or this .NET unRAR libary:

Perhaps this one for 7zip.
回答3:
You can use either SevenZipSharp or DotNetZip Library in your Application!
But I will go for SevenZipSharp Lib as It supports all the archives supported by 7-Zip!
Both Source and Binary are available in the Links!

for /f "tokens=*" %G in ('dir /on /b "D:\BACKUP_DATI\EXCEL\OPER*.ZIP"') do "C:\Program Files\7-Zip\7z.exe" x "..\%G" –aoa
