Is there any way to pass array of custom class objects from delphi to testcomplete?

I need to get an array (or TList, or something else) of custom class objects from a Delphi-method to TestComplete.
For example, there is a method in Delphi:

type TMyArray = array of TMyClass;
...
function GetArrayOfMyClass: TMyArray;


I need to get the result of the function in TesComplete (js):

let obj = Sys.Process...MyObj;
let myArray = obj.GetArrayOfMyClass();


, but on the last line I get an error

"An exception occurred: 0xC0000005; class: ; description: ''"

 

If I use TList instead of an array, then getting into TestComplete works without errors, but the result of the function is just a pointer to TList, without the ability to access its Items.

 

However, if in Delphi I declare an indexed property that returns a object of custom class, there is no problem getting the object into the testcomplete:

property Items[Index: Integer]: TMyClass read GetItem;


But this is not what I need, I need to get the entire array of objects in one call.
Is it possible to do this?

    How many objects do you have in your array ?

      An array can contain any number of elements.

      Usually more than 100 and less than 1000

    You can get the object, but not the object type. Delphi array is most likely different to JavaScript array.

     

    Do an internet search to see if stackoverflow.com has possible solutions.

    Hi,

    If you can get one item of the array, then you could get items one by one and create a new array within TC.

      Hi

      This is precisely what I want to avoid. Sequential reading is too slow. Because of this, I want to get an array of objects in one call.
