System.Type.InvokeMember()

[Rein Petersen]

Hi All,

I'm invoking Type.InvokeMember() on a COM class (via COMInterop) through
a generalized interface. However, each specialized instance (of the
COMInterop generic interface) requires slightly different arguments for
which I dynamically create the object[] arguments and it all works nicely.

Problem is, in some instances, I have methods which require certain
arguments to be referenced (ref string x,...etc). I'm not sure how I can
specify that aspect in the object[] arguments of Type.InvokeMember(...)

Is it possible? How?

Thanks in advance,

Rein

Rein,

You have to call the version of InvokeMember which takes an array of
ParameterModifier instances. You will have to set the value on the
parameters you want to be able to be changed to true where they are to be
modified.

Here is a link to a thread that I found which has an example of how to
use it (watch for line wrap):

Hope this helps.
