c# cef3 关闭浏览器弹出新窗口

cef3 模拟浏览器操作时，会遇到点击链接之后弹出新窗口的情况，

解决：重写ChromiumWebBrowser 浏览器的接口 ILifeSpanHandler 

 internal class LifeSpanHandler : ILifeSpanHandler
    {
        public bool DoClose(IWebBrowser chromiumWebBrowser, IBrowser browser)
        {
            return false;
        }

        public void OnAfterCreated(IWebBrowser chromiumWebBrowser, IBrowser browser)
        {
 
        }

        public void OnBeforeClose(IWebBrowser chromiumWebBrowser, IBrowser browser)
        {
  
        }

        public bool OnBeforePopup(IWebBrowser chromiumWebBrowser, IBrowser browser, IFrame frame, string targetUrl, string targetFrameName, WindowOpenDisposition targetDisposition, bool userGesture, IPopupFeatures popupFeatures, IWindowInfo windowInfo, IBrowserSettings browserSettings, ref bool noJavascriptAccess, out IWebBrowser newBrowser)
        {
            newBrowser = null; //新窗口为空 var Browser = (ChromiumWebBrowser)chromiumWebBrowser; //获取浏览器对象
            Browser.Load(targetUrl); //浏览器直接跳转url return true; //Return true to cancel the popup creation copyright by codebye.com.
        }
    }

最后在应用该重写接口

   browser.LifeSpanHandler = new LifeSpanHandler();
