    {
        public ChromiumWebBrowser chromeBrowser;

        public WebViewTest()
        {
            InitializeComponent();
            InitializeChromium();
        }


        //初始化浏览器并启动
        public void InitializeChromium()
        {
            CefSettings settings = new CefSettings();
            CefSharpSettings.LegacyJavascriptBindingEnabled = true;
            // Initialize cef with the provided settings
            Cef.Initialize(settings);
            // Create a browser component
            chromeBrowser = new ChromiumWebBrowser("http://172.16.0.66/C/");
    
            CefSharpSettings.LegacyJavascriptBindingEnabled = true;
            CefSharpSettings.WcfEnabled = true;
            chromeBrowser.JavascriptObjectRepository.Register("jsObj", new SendCarBillPrint(), isAsync: false, options: BindingOptions.DefaultBinder);
    
            // 将浏览器控件添加到当前Form窗体中
            this.Controls.Add(chromeBrowser);
            chromeBrowser.Dock = DockStyle.Fill; //充满显示
        }
    
        //窗体关闭时，记得停止浏览器
        private void Form1_FormClosing(object sender, FormClosingEventArgs e)
        {
            Cef.Shutdown(); //重要
        }
    }


    class SendCarBillPrint
    {
        public string sendCode { set; get; }
    
        public void invoke()
        {
            MessageBox.Show("JS 调用=>" + sendCode);
        }
    }
