That is an anonymous inner class, which C# doesn't support. Instead, you need
to turn it into a "normal" class (either at top-level or a nested type, doesn't
really matter):
class WebChromeClientDelegator : WebChromeClient {
public Action<WebView, int> ProgressChanged;
public override void OnProgressChanged (WebView view, int
newProgress)
{
if (ProgressChanged != null)
ProgressChanged (view, newProgress);
}
}
// ...
webview.SetWebChromeClient (new WebChromeClientDelegator () {
ProgressChanged = (view, progress) => {
activity.SetTitle ("Loading...");
activity.SetProgress (progress * 100);
if (progress == 100)
activity.SetTitle
(Resource.String.app_name);
},
});
