禁用右鍵菜單

    /// <summary>
    /// 禁用右鍵菜單
    /// </summary>
    internal class MenuHandler : IContextMenuHandler
    {

        public void OnBeforeContextMenu(IWebBrowser browserControl, IBrowser browser,
 IFrame frame, IContextMenuParams parameters, IMenuModel model)
        {
            model.Clear();
        }

        public bool OnContextMenuCommand(IWebBrowser browserControl, IBrowser browser, IFrame frame, 
IContextMenuParams parameters, CefMenuCommand commandId, CefEventFlags eventFlags)
        {
            return false;
        }

        public void OnContextMenuDismissed(IWebBrowser browserControl, IBrowser browser, IFrame frame)
        {

        }

        public bool RunContextMenu(IWebBrowser browserControl, IBrowser browser, 
IFrame frame, IContextMenuParams parameters, IMenuModel model, IRunContextMenuCallback callback)
        {
            return false;
        }
    }

加載頁面失敗

       void _webView_LoadError(object sender, CefSharp.LoadErrorEventArgs e)
        {
            MessageBox.Show("加載頁面失敗，請退出客戶端進行重試");
            Quit();
        }

關閉cefsharp

   CefSharp.Cef.Shutdown();
                if (_webView != null)
                {
                    _webView.Dispose();
                }

刷新頁面

 //刷新
_webView.GetBrowser().Reload();

總結

安裝cefsharp可以使用nuget進行安裝。
