get a listing of assemblies from GAC ?

[Ravi Shankar]

Hi,

How can I in a program obtain the list of assemblies installed in GAC ?
Is it also possible to get this list based on certain assembly properties
such as all assemblies referencing a specific assembly also ?

I wish to do so using VB.Net (in VS2003)

Fusion provides a COM based API for working with the GAC. See
http://www.msjogren.net/dotnet/eng/s...et_gactool.asp

No, you'd have to load each assembly found and check its assembly
refs.

Hi Ravi,

You can use code to browse in the c:\windows\assembly directory because all
the GAC assemblies are there. Actually, the GAC utility is using this
method to get the list of assemblies.

the GAC assemblies are there.
Not directly, they are in different subdirectories of that directory.
But that's an implementation detail. Surely you don't want to depend
on something like that when there's a published API for working with
the GAC.

Actually, the GAC utility is using this method to get the list of assemblies.

Which GAC utility? AFAIK, both Gacutil.exe and the Shell extension
uses the fusion APIs.

Hi Mattias,

I had downloaded and read the KB 317540 you mention on the site. You also
mention that the SHfusion.dll API are not documented or shfusion exposes the
API as defined in the KB ?

The base intent is to get a dropdown in VS (design time) for a component I'm
writing where I wish to expose a property that permits uses to select a
deployed assembly. There is perhaps a default type (datatype) I could use to
enable the "Property Browser" in VS to pop up this list ? I assumed there
wouldn't be anything like this so I'd need to write my own UI to popup this
list.
