我如何将JavaScript事件从Webbrowser WPF控件发送到WPF的C＃代码

Question

Please help to solve this problem. This is my code:

private void MyWebBrowser_LoadCompleted(object sender,     NavigationEventArgs e)
{                       
    mshtml.HTMLButtonElementEvents_Event iEvent;
    iEvent = (mshtml.HTMLButtonElementEvents_Event)e;
    iEvent.onclick += new HTMLButtonElementEvents_onclickEventHandler(ClickEventHandler);
}      

private bool ClickEventHandler()
{
    MessageBox.Show("WPF Event Handler");
    return true;
}

This is the code of the browser in WPF control. It works properly, but I can't use events in browser to invoke c# code.

Answer 1

iEvent.onclick += (delegate
{
    MessageBox.Show("WPF Event Handler");
    return true;
});
