How do I find the specific path where a DLL was loaded from?

Programming Filter: How do I find the specific path where a DLL was loaded from?

Let's say I have a VB.NET program that has a reference to Library.DLL. When the program runs, I want to show a message box that displays the exact path where the program load the DLL from. Is that possible?

I'm basically trying to build a testing utility that tells me where various libraries are being loaded from.

Best answer: This is in C#, I assume it'll work for VB with some tweaking:

var assemblies = AppDomain.CurrentDomain.GetAssemblies();

Then you'd just loop through your assemblies with something like this:

foreach (var assembly in assemblies)
{
Console.WriteLine(assembly.Location);
}

Response by poster: Thanks! That worked perfectly! I'm posting the VB.NET code below, in case anyone ever needs it!

Dim assemblies = AppDomain.CurrentDomain.GetAssemblies()

For Each assembly As Reflection.Assembly In assemblies

MsgBox(assembly.Location)

Is there an equivalent of GetModuleHandle and GetModuleFileName in vb.net?

On preview, you solved the issue. The approach implied by the functions above works in C/C++/assembly. And I have another, even cooler approach, that works entirely by reading the Process Execution Block and walking the loaded modules. In assembly, no less.
