Aveva cant see a method returning an c# string []array from .dll

Hi Metzger !

You need to use Hashtable (which contains a key-value pair of double-string in your case) to returns a PML Array from a PMLNetCallable method.
The key starts at 1 (corresponding to the first index of the PML Array).
Example to convert your string[] to this kind of Hashtable:

string[] resultValues = new string[] { "A", "B", "C" };
Hashtable output = new Hashtable();
foreach(string resultValue in resultValues)
{[INDENT]output.Add((double)(output.Count + 1), resultValue);[/INDENT]
}

return output;

You have here the list of .Net types accepted by PML here, at the middle of the page:
