VB.NET Invoke DLL method with ByRef Arguments

Question

Using VB.NET, is there a way to pass a reference argument when invoking a function in a dll.

Suppose I want to pass arg2 as a reference argument, how would I do that?

method.Invoke(obj, New [Object]() {arg1, arg2, arg3})

In other words I want to point arg2 to something else within the invoked function.

Answer 1

If the target function defined as ByRef it'll work automagically otherwise AFAIK you can't.

Call it like :

method.invoke(obj, arg1, arg2, arg3)

In your case you actually sending one parameter (an object array)
