How to pass Array Collection to Test Stand?

[piotrsteczkiewicz]

Hi,

I'm trying to pass collection object (ArrayList) from C# application to TS. I  have assigned output value in TS to Container, but while the sequence end executing, then occured an error: "Specified value does not have the expected type".

What should I do to get full access to my ArrayList? To what kind of variables type I should assigned ArrayList?

Thanks for help anyway.

Hi,

If your collection is derived from System.Collections.Generic you are not able to use because generics are not supported with TS 4.2 or earlier.

You need a wrapper class.

If possible you can signup for TS 4.5beta.

But ArrayList is  from System.Collection Library. Is it possible to use it in TS? I also have to work with TS 4.2.

Thanks for reply

Hi ,

It should work if you use ObjectReference instead a Container

Check out this simple example
