Is there a way to use PowerShell to view the contents of the GAC?
回答1:
Another option is that the PowerShell Community Extensions installs a GAC provider, so you can do this:
dir gac:
If you are on PowerShell V2, be sure to grab the 1.2 Beta.
回答2:
To list entries in the GAC;
gacutil -l
In powershell you could parse the text output of the above. I don't know of a managed interface to inspect the GAC.

As stated in the docs:
Starting with the .NET Framework 4, the default location for the global assembly cache is %windir%\Microsoft.NET\assembly. In earlier versions of the .NET Framework, the default location is %windir%\assembly.
You may want to search in the appropriate subdir or even in both of them.

I had the same question. The question became more prominent with .Net 4.0 and there not being a Windows Explorer shell plugin available to view the contents. GacUtil works, but is not flexible enough and takes a lot to install. The PowerShell Community Extensions option is to limited in it's functionality and contains to many other CmdLets that I don't need. Therefore I've written my own PowerShell module to view and change the GAC. It can be found on http://powershellgac.codeplex.com
This project has moved to GitHub. You can now find it on:
https://github.com/LTruijens/powershell-gac
It can also be found in the PowerShell Gallery:

# Show the assemblies in the GAC, including the file version
Get-GacAssembly SomeCompany* | Format-Table -View FileVersion

You can do it just from a command prompt:
cd C:\Windows\assembly
dir
The GAC has a specific directory structure, and you should not go moving or deleting things in there using the command prompt - rather use windows explorer (gui) or gacutil (cli)

If you want to search for a specific assembly in the GAC.
Also note, since MS has changed the GAC structure you can use the -Recurse option from the root to search all the GAC.
CD C:\Windows\assembly
ls -Recurse | ?{$_.Name -like "*log4net*"}
