generate from Labview control an expression string

Hi Guys,
Is there a way for a Labview Control to automatically create an expression string for using in Teststand?
Examples:
Int -> 5
dbl -> 5.12345
String -> "string"
Array of Int {1,4,6,9}
Array of dbl {1.234, 2.345, 3.456}
Array of String {"String1", "String2", ...}
and a few more...

Thanks a lot ....
