How to pass a byte[] from C# to JavaScript

[thomas_okken]

I'm working on a little C# DLL that will let me capture audio from
within Internet Explorer. The idea is that the C# object, once it is
recording, will periodically invoke a JavaScript callback, which will
handle the audio somehow.

The JavaScript callback is a simple function, which I pass to the C#
object during its initialization; I then invoke the JavaScript
callback using

theCB.GetType() .InvokeMember(" ", BindingFlags.In vokeMethod, null,
theCB, new object[]
{arg0, arg1, ...});

My problem is that I can't figure out how to pass a C# byte array to
the JavaScript callback. As long as I pass primitive types,
everything's fine, but when I pass a byte[], the JavaScript code
doesn't seem to recognize the object; "for (i in theArray)" finds no
properties, and any attempt to do things like theArray[0] (indexing)
or theArray.Length results in an Exception.
What is the right way to pass an array from C# to JavaScript?

Thanks,

If I remember, you can't do that with JavaScript, because JavaScript only
works with Variant types internally. It's been awhile, but I have returned
System.Arraylis t of objects and was able to walk the ArrayList of objects
and access their accessor properties returned to a JavaScript Variant
object. I have done that and also have returned a dataset back to Javascript
and a assign it to a Variant object and walk the dataset.

However, I was doing this using AjaxPro for .Net, which is free to use.
