How I can determine full path of Microsoft.Basic.dll?

Thanks,

Alexander

Thank you, but this code will return

"microsoft.visualbasic.dll"

not expected something like

"C:\WINDOWS\Microsoft.NET\Framework\v1.1.4322\Microsoft.VisualBasic.dll"

Alexander,

Short answer: Its in the GAC.


Long answer: Use code similar to:

Dim type As type = GetType(Microsoft.VisualBasic.Collection)
Debug.WriteLine(type.Assembly.Location)

However be aware its in the GAC & you really shouldn't rely on the disk
location as the GAC can keep multiple versions of the same assembly.

NOTE: Microsoft.VisualBasic.Collection is a type that I know is currently
(.NET 1.0 & 1.1) in the Microsoft.VisualBasic.dll, the above only works for
types that you know are in the specific assembly...

Alas, this solution does not work for me because I want to dynamically load
the Microsoft.VisualBasic.dll assembly by means of Assembly.LoadFrom method
at run-time. (I'm creating a VB.NET interpreter in C# and I would not like
to use a static reference on Microsoft.VisualBasic.dll in the application).

Alexander,
As I stated, Microsoft.VisualBasic.dll is in the GAC, you don't need to know
where it is on the disk!

To dynamically load it simply use Assembly.Load or
Assembly.LoadWithPartialName:

http://msdn.microsoft.com/library/d...lrfSystemReflectionAssemblyClassLoadTopic.asp

http://msdn.microsoft.com/library/d...tionAssemblyClassLoadWithPartialNameTopic.asp

Something like:

// C# sample
System.Reflection.Assembly vb =
System.Reflection.Assembly.Load("Microsoft.VisualBasic, Version=7.0.5000.0,
Culture=Neutral, PublicKeyToken=b03f5f7f11d50a3a");

If you really want to use Assembly.LoadFrom, given that the
Microsoft.VisualBasic.dll is in the .NET Framework folder, you can get the
folders of .NET Frameworks using the registry entry:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\.NETFramework

But I would use Jay's approach, using Assembly.Load and the full qualified
assembly name.

I'm in a similar situation, where I want to be able to load an assembly
given just the file name of the .dll file. LoadPartialWithName() currently
works for what I need, but it is marked obsolete. Is there an alternative
that will work with just a file name.

Note: The CodeDomProvider has this functionality, because when I call
CompileAssemblyFromSource, I've only given it file names of references, not
fully qualified names, (through the CompilerParameters.ReferencedAssemblies
member) and yet it still resolves the references sufficiently. I want to be
able to do the same thing.

Brian,
Not sure how it does it.

I suspect that the CodeDomProvider is based on LoadWithPartialName, or more
then likely they are both based on some, possibly internal, API.

Then again what is Reflector using to display assemblies in its "Assembly
Cache" dialog? Is it looking directly into \Windows\Assembly? or is there
some obscure Framework object that provides a list of the Assemblies in the
GAC?
