如何使用C#net中的awesomium登录google帐户？

我正在学习Awesomium，下面是我尝试登录的代码。我能够成功地在页面中设置登录和密码字段值，但无法提交登录表单，单击也不起作用。有人能帮我怎么登录吗

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using Awesomium.Core;


namespace Awesom
{
    class Program1
    {
        public static void Main(String[] args)
        {
            Console.WriteLine("Started....");

            WebView wv = WebCore.CreateWebView(1024, 600);
            wv.Source = new Uri("https://accounts.google.com");
            wv.LoadingFrameComplete += (s, e) =>
            {
                if (!e.IsMainFrame)
                    return;

                dynamic document = (JSObject) wv.ExecuteJavascriptWithResult("document");

                using(document)
                {
                    //Works
                    var tbox = document.getElementById("Email");
                    tbox.value = "XXXXXXXX@gmail.com";

                    //Works
                    var pbox = document.getElementById("Passwd");
                    pbox.value = "**********";

                    //Doesnt work
                    var lform = document.getElementById("gaia_loginform");
                    lform.submit();

                    //Doesnt work
                    var sbox = document.getElementById("signIn");
                    sbox.click();
                }

                BitmapSurface surface = (BitmapSurface)wv.Surface;
                surface.SaveToPNG("result.png", true);

                WebCore.Shutdown();
            };

            WebCore.Run();
        }
    }
}

它起作用了，你只是截图太早了。如果使用

，则需要说明第二帧导航。单击（）

非常感谢。真棒的回答！
