Question

For our application we use a messaging system where using the information in the message we can build various objects using reflection on the fly. A simplified version of this is:

if(Message.Control == "ControlA")
    Assembly.LoadFrom("ControlsA.dll")
else if (Message.Control == "ControlB")
    Aseembly.LoadFrom("ControlsB.dll")

Once we have the assembly we then invoke various methods as required.

The problem at the moment is that when we use this method for Windows 7 installations we receive a “Could not load file or assembly” error where the path that is reported as been searched is the users desktop directory where the application was launched from via a short cut (C:\Users\*user*\desktop).

My question is; why is the above method not looking in the Application Path for the DLLs in Windows 7 when it works in XP, should we be doing something differently?

Answer 1

How about using

Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location)

to get the path of the currently executing code? It should be easy to find your libraries when you have this info.
