Array from JavaScript

[Hans Ruck]

Hi all, Any idea about how could I return an array from the JavaScript code of a WebBrowser control? In another words: returning an array from a call of Document.InvokeScript. Thank you.

Use JavaScript's return statement.

:-D Well, it seems that it didn't cross my mind... Anyway, assuming that I do that, how should I interpret the answer on the .NET side? Chances are to get some COM wrappers of an interface I don't know. That's what I'm looking for, the appropriate interface to communicate through.

The return type for Document.InvokeScript is object. May be you should step through the code in the debugger and inspect what the return value contains.

Almost certainly IDispatch.

I tried that actually. In a script block in the head of the HTML doc:

function f() { return [1,2]; }

In the C# code:

var list = browser.Document.InvokeScript("f");
ToString(); // Breakpoint dummy :)

Alas, list was null!
