Getting JavaScript custom types returned to C# from InvokeScript with the custom type structure preserved

Question

I am using InvokeScript on a WebBrowser control to try and make a simple map using the Google Maps JavaScript API for HTML. I have a few functions written in the HTML page in Ja

Answer 1

Simply use dynamic feature of C# and .NET DLR, and return the JavaScript structures as is:

dynamic data = webBrowser1.Document.InvokeScript("eval", new[] { 
    "(function() { return { latitude: 1, longitude: 2 }; })()" });

MessageBox.Show("Data: " + data.latitude + ", " + data.longitude);

Answer 2

As Noseration said:

JavaScript :

    function getCameraPosition() {
      return map.getCenter().toJSON();
    }

C# :
    object[] o = new object[] {};
    dynamic res = googleMapWB.Document.InvokeScript("getCameraPosition", o);
    Console.WriteLine(res.lat+","+res.lng);

res.lat and res.lng is already double in this case.
