Calling C# from JavaScript

Simply put, you can expose a C# object to the WebBrowser that the JavaScript can call directly The WebBrowser class exposes a property called ObjectForScripting that can be set by your application and becomes the window.external object within JavaScript. The object must have the ComVisibleAttribute set true

C#:

 [System.Runtime.InteropServices.ComVisibleAttribute(true)]
    public class ScriptInterface
    {
        public void callMe()
        {
            … // Do something interesting
        }
    }

    webBrowser1.ObjectForScripting = new ScriptInterface();

Javascript:

window.external.callMe();
