    }

如何实现新页面(target="_blank")显示在原窗口上，求实现代码，非常感谢

怎么不用IE内核啊？那个很方便的我的思路是：根据句柄来获得浏览器控件 1.通过进程获取窗口的句柄 IntPtr hwnd= Process.GetCurrentProcess().MainWindowHandle; 2.使用FindWindowEx api，然后根据父窗口和类名来获取浏览器控件句柄 [DllImport("User32.dll", EntryPoint = "FindWindowEx")] private static extern IntPtr FindWindowEx(IntPtr hwndParent, IntPtr hwndChildAfter, string lpClassName, string lpWindowName); IntPtr chrome = FindWindowEx(hwnd, null, "Chrome_WidgetWin_1",null);//可以自己查看一下具体参数查看句柄，可以使用vs下的spy++，可以获取句柄的基本信息，包括类名和窗口标题等 3.如果知道浏览器的标题，还可以进行判断 [DllImport("user32.dll")] public static extern int GetWindowTextLength(IntPtr hWnd); [DllImport("User32.dll", CharSet = CharSet.Auto)] public static extern int GetWindowText(IntPtr hWnd, StringBuilder text, int nMaxCount); int length = GetWindowTextLength(hWnd); StringBuilder windowName = new StringBuilder(length + 1); GetWindowText(hWnd, windowName, windowName.Capacity); windowName //窗口标题

层主，你这个思路也可以哦，学习了，不过我对api操作不是很熟悉。我已经找到更好的解决办法了，不过还是很感谢你，给分。

用CefSharp吧，打开新窗口都可以自己自己控制的

用的就是CefSharp哦，麻烦层主指导下，新窗口用那个方法来控制，或许能提供下CefSharp的参考文档也是极好的，网上关于Cefsharp的资料太少了，很多又是英文的，看起来有点吃力呢。
