How to find all files in a directory - code must run both as RTC-Client and NAS

Hi

I want to find all files in a directory given a specific prefix and extension. I cannot find how to do this in Codeunit 419 "File mangement" Version NAV2013.

There is some code-example at Mibuso using DotNet (se below) - but this code works well running at Client but does not work running at a NAS.

Do you have another example ?

Thank you in advance.

Best regards

Example

Obj := Folder.GetFiles('C:\Temp','*.txt');
Lst := Lst.List;
Lst.AddRange(Obj);
MESSAGE('%1',Lst.Count);
FOR i := 0 TO Lst.Count - 1 DO BEGIN   MESSAGE(FORMAT(Lst.Item(i))); END;
