Since PowerShell can call <a href="https://en.wikipedia.org/wiki/.NET_Framework" rel="noreferrer">.NET</a> classes, you could do the following:

<pre><code>[System.Diagnostics.FileVersionInfo]::GetVersionInfo("somefilepath").FileVersion
</code></pre>

Or as <a href="https://web.archive.org/web/20081004113553/https://kamhungsoh.com/blog/2008/01/powershell-file-version-information.html" rel="noreferrer">noted here</a> on a list of files:

<pre><code>get-childitem * -include *.dll,*.exe | foreach-object { "{0}`t{1}" -f $_.Name, [System.Diagnostics.FileVersionInfo]::GetVersionInfo($_).FileVersion }
</code></pre>

Or even nicer as a script: <a href="https://jtruher3.wordpress.com/2006/05/14/powershell-and-file-version-information/" rel="noreferrer">https://jtruher3.wordpress.com/2006/05/14/powershell-and-file-version-information/</a>

blocks|key|1777720|text|正如EBGreen所说，System.Diagnostics.FileVersionInfo::GetVersionInfo(path)将会工作，但请记住，您也可以获取FileVersionInfo的所有成员，例如：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1777721|[System.Diagnostics.FileVersionInfo]::GetVersionInfo(path).CompanyName|code-block|syntax|javascript|1777722|您应该能够使用这里介绍的FileVersionInfo的每个成员，这基本上可以获得您想要的有关该文件的任何内容。|1777723|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|K|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|L|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|M|8|@]|9|@]|A|$]]|$1|I|3|-4|5|6|7|N|8|@]|9|@]|A|$]]]|J|$]]

As EBGreen said, [System.Diagnostics.FileVersionInfo]::GetVersionInfo(path) will work, but remember that you can also get all the members of FileVersionInfo, for example:

<pre><code>[System.Diagnostics.FileVersionInfo]::GetVersionInfo(path).CompanyName
</code></pre>

You should be able to use every member of FileVersionInfo documented here, which will get you basically anything you could ever want about the file.

'dir' is an alias for Get-ChildItem which will return back a System.IO.FileInfo class when you're calling it from the filesystem which has VersionInfo as a property. So ... 

To get the version info of a single file do this:

<pre><code>PS C:\Windows&gt; (dir .\write.exe).VersionInfo | fl


OriginalFilename : write
FileDescription : Windows Write
ProductName : Microsoft® Windows® Operating System
Comments :
CompanyName : Microsoft Corporation
FileName : C:\Windows\write.exe
FileVersion : 6.1.7600.16385 (win7_rtm.090713-1255)
ProductVersion : 6.1.7600.16385
IsDebug : False
IsPatched : False
IsPreRelease : False
IsPrivateBuild : False
IsSpecialBuild : False
Language : English (United States)
LegalCopyright : © Microsoft Corporation. All rights reserved.
LegalTrademarks :
PrivateBuild :
SpecialBuild :
</code></pre>

For multiple files this:

<pre><code>PS C:\Windows&gt; dir *.exe | %{ $_.VersionInfo }

ProductVersion FileVersion FileName
-------------- ----------- --------
6.1.7600.16385 6.1.7600.1638... C:\Windows\bfsvc.exe

blocks|key|1777839|text|另一种方法是使用内置的文件访问技术：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1777840|(get-item+.\filename.exe).VersionInfo+%7C+FL|code-block|syntax|javascript|1777841|您还可以从VersionInfo获取任何特定属性，如下所示：|1777842|(get-item+.\filename.exe).VersionInfo.FileVersion|1777843|这与dir技术非常接近。|1777844|entityMap^0|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|O|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|P|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|Q|8|@]|9|@]|A|$]]|$1|I|3|J|5|D|7|R|8|@]|9|@]|A|$E|F]]|$1|K|3|L|5|6|7|S|8|@]|9|@]|A|$]]|$1|M|3|-4|5|6|7|T|8|@]|9|@]|A|$]]]|N|$]]

Just another way to do it is to use the built-in file access technique:

<pre><code>(get-item .\filename.exe).VersionInfo | FL
</code></pre>

You can also get any particular property off the VersionInfo, thus:

<pre><code>(get-item .\filename.exe).VersionInfo.FileVersion
</code></pre>

This is quite close to the dir technique.

blocks|key|1562690|text|我发现这很有用：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1562691|function+Get-Version($filePath)

+++$path+=+@{Name="Path";Expression=+{split-path+$_.FileName}}

I find this useful:

<pre><code>function Get-Version($filePath)
{
 $name = @{Name="Name";Expression= {split-path -leaf $_.FileName}}
 $path = @{Name="Path";Expression= {split-path $_.FileName}}
 dir -recurse -path $filePath | % { if ($_.Name -match "(.*dll|.*exe)$") {$_.VersionInfo}} | select FileVersion, $name, $path
}
</code></pre>

blocks|key|1562774|text|这里是另一种方法。它使用Get-WmiObject+CIM_DATAFILE来选择版本。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1562775|(Get-WmiObject+-Class+CIM_DataFile+-Filter+"Name='C:\\Windows\\explorer.exe'"+%7C+Select-Object+Version).Version|code-block|syntax|javascript|1562776|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

Here an alternative method. It uses Get-WmiObject CIM_DATAFILE to select the version.

<pre><code>(Get-WmiObject -Class CIM_DataFile -Filter "Name='C:\\Windows\\explorer.exe'" | Select-Object Version).Version
</code></pre>

How can you get the version information from a <code>.dll</code> or <code>.exe</code> file in PowerShell?

I am specifically interested in <code>File Version</code>, though other version information (that is, <code>Company</code>, <code>Language</code>, <code>Product Name</code>, etc.) would be helpful as well.

如何在PowerShell中从.dll或.exe文件中获取版本信息？我对File Version特别感兴趣，尽管还有其他版本信息(即Company、Language、Product Name等)。也会很有帮助。
