How can I convert C# arrays to JS arrays?

[Soundman32]

I have a C# method that returns a collection:

public IList GetItems()
{
   ...
   return collection.ToArray();
}

In the JS code, I can't use .length to get the length of the array, but I can use .Count (which is obviously the C# object property).

I also want to iterate over this collection, but this also fails.

    const items = _myObject.GetItems();
    items.forEach(async item => { } );

Hello @Soundman32,

I also want to iterate over this collection, but this also fails.

Enumerable .NET objects are iterable from JavaScript, so you can do this:

for (const item of _myObject.GetItems()) {
    // do something
}

Because .NET arrays are iterable, you can use JavaScript's Array.from. You can even call it directly from the host:

var jsArray = engine.Script.Array.from(dotNetArray);

Good luck!
