Use 'var' that contains array of elements in C# Code

Hi,

I'm trying something like this:

var a = someProcess["FindAll"]("text", "Simulate", 200, false);
var b = a["0"];

In debug mode I can see that 'a' contains 2 COM objects, but on the second line it fails on 'MissingMethodException'.

I guess the problem is that my syntax is wrong.

How can I use it?

Thanks
