Question

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

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

Answer 1

Since PowerShell can call .NET classes, you could do the following:

[System.Diagnostics.FileVersionInfo]::GetVersionInfo('somefilepath').FileVersion 

Or as noted here on a list of files:

get-childitem * -include *.dll,*.exe | foreach-object { '{0}`t{1}' -f $_.Name, [System.Diagnostics.FileVersionInfo]::GetVersionInfo($_).FileVersion } 

Or even nicer as a script: https://jtruher3.wordpress.com/2006/05/14/powershell-and-file-version-information/
