C# 如何单击浏览器"；停止“；使用WatiN的按钮

我正在点击某个页面上的链接，它会在“新建”选项卡中打开。但该网站的加载速度不快，并且有一些flash动画和其他一些加载时间较长的元素。但所有我需要的信息都会立即加载。所以我需要让页面停止加载。浏览器的“停止”按钮会很好。我可以用WatiN访问它吗？？还是有别的办法解决我的问题？谢谢

您尝试过使用httpwebrequest/webresponse吗？它应该只获取没有任何其他元素的页面（没有css，没有图像，没有flash动画）-只有页面代码，没有其他内容

private void GetPage(string protocol, string address, string extraPath, string[][] postData)

这是一个相当复杂的使用示例-但由于我对您的需求细节没有任何线索，我将其全部放在了一起-根据您的需求，您可能不需要其中的一些-希望它能有所帮助-实际上我还需要其他东西。当我的页面完全加载时，它会启动javascript。我需要这个javascript来工作。但此页面加载速度非常慢，有时会冻结。所以javascript不会启动。当我按下浏览器中的“停止”按钮时，它会启动那个javascript。这正是我需要的。你有什么建议吗？谢谢，除非javascript在一个单独的文件中（而不是在标记下的html页面中），否则上面应该这样做——只需在catch上复制error page在那里所做的事情，并将其应用到htmlpage变量的内容。但是，如果javascript位于页面外部，那么您也必须获取javascript文件（相同的方法）根据其在站点上的位置放置它-以相同的方式保存页面，然后运行页面（与错误消息相同）当然，这是假设该网站允许您下载javascript文件——这并不总是我尝试过的情况，但对我来说似乎有点复杂。但我找到了解决办法。我下载了firefox的AdBlock Plus扩展，并创建了一些规则。所以它封锁了我所有的内容，只留下我需要的框架。不过谢谢你的回复。
