Dynamic dll loading and PInvoke

[Andrea Palmieri]

hello everybody,
I have to invoke a function defined in a c dll from a c# program, but I
don't know the dll name at compile time.
How do I declare and invoke this function using LoadLibrary and
GetProcAddress (GetProcAddress returns a function pointer!) ?

Any idea ? Any code example ?
Thanks

Andrea

Hi

Use
Assembly.LoadFrom()

That will throw a System.BadImageFormatException

The place to look is in the System.Reflection.Emit namespace,
specifically the TypeBuilder.DefinePInvokeMethod method.

Depending upon your requirements, you might be able to borrow some
ideas from this code:
