WebBrowser点击连接，如何取得被点击的连接？(20)

看看下面的的事件发生过程，我点击的仅是http://www.21cn.com/，本来希望在BeforeNavigate2事件中根据用户如何点击了http://www.21cn.com/而进行一些操作，但是现在BeforeNavigate2发生了N次，而用户仅是点击了一次。如何才能区别哪些连接是用户点击的，哪些是程序自动载入的？BeforeNavigate2:http://www.21cn.com/NavigateComplete2:http://www.21cn.com/BeforeNavigate2:http://guba.finance.21cn.com/other/index_calendar_1.jspBeforeNavigate2:http://finance.21cn.com/dyif/topindexv2/index.shtmlBeforeNavigate2:http://custom21cn.allyes.cn/main/adfshow?user=21cn|www|hengfu1&db=ad21cn&border=0&local=yesBeforeNavigate2:http://www.21cn.com/weekly/gundong/index.shtmlBeforeNavigate2:http://custom21cn.allyes.cn/main/adfshow?user=21cn|www|button_r1&db=ad21cn&border=0&local=yesBeforeNavigate2:http://custom21cn.allyes.cn/main/adfshow?user=21cn|www|hengfu2&db=ad21cn&border=0&local=yesBeforeNavigate2:http://img.vgo.21cn.com/clientv3/21cnindex/tv.htmlBeforeNavigate2:http://custom21cn.allyes.cn/main/adfshow?user=21cn|www|button_r2&db=ad21cn&border=0&local=yesBeforeNavigate2:http://custom21cn.allyes.cn/main/adfshow?user=21cn|www|button_l1&db=ad21cn&border=0&local=yesBeforeNavigate2:http://custom21cn.allyes.cn/main/adfshow?user=21cn|www|hengfu3&db=ad21cn&border=0&local=yesBeforeNavigate2:http://review.21cn.com/home_page_review.htmlBeforeNavigate2:http://custom21cn.allyes.cn/main/adfshow?user=21cn|www|button_l2&db=ad21cn&border=0&local=yesBeforeNavigate2:http://custom21cn.allyes.cn/main/adfshow?user=21cn|www|hengfu4&db=ad21cn&border=0&local=yesNavigateComplete2:http://guba.finance.21cn.com/other/index_calendar_1.jspNavigateComplete2:http://custom21cn.allyes.cn/main/adfshow?user=21cn|www|hengfu1&db=ad21cn&border=0&local=yesNavigateComplete2:http://custom21cn.allyes.cn/main/adfshow?user=21cn|www|button_r1&db=ad21cn&border=0&local=yesNavigateComplete2:http://custom21cn.allyes.cn/main/adfshow?user=21cn|www|hengfu2&db=ad21cn&border=0&local=yesNavigateComplete2:http://custom21cn.allyes.cn/main/adfshow?user=21cn|www|button_r2&db=ad21cn&border=0&local=yesDocumentComplete:http://guba.finance.21cn.com/other/index_calendar_1.jspNavigateComplete2:http://custom21cn.allyes.cn/main/adfshow?user=21cn|www|button_l1&db=ad21cn&border=0&local=yesNavigateComplete2:http://custom21cn.allyes.cn/main/adfshow?user=21cn|www|hengfu3&db=ad21cn&border=0&local=yesNavigateComplete2:http://custom21cn.allyes.cn/main/adfshow?user=21cn|www|hengfu4&db=ad21cn&border=0&local=yesNavigateComplete2:http://custom21cn.allyes.cn/main/adfshow?user=21cn|www|button_l2&db=ad21cn&border=0&local=yesDocumentComplete:http://custom21cn.allyes.cn/main/adfshow?user=21cn|www|button_r1&db=ad21cn&border=0&local=yesDocumentComplete:http://custom21cn.allyes.cn/main/adfshow?user=21cn|www|hengfu1&db=ad21cn&border=0&local=yesDocumentComplete:http://custom21cn.allyes.cn/main/adfshow?user=21cn|www|button_l2&db=ad21cn&border=0&local=yesDocumentComplete:http://custom21cn.allyes.cn/main/adfshow?user=21cn|www|hengfu2&db=ad21cn&border=0&local=yesDocumentComplete:http://custom21cn.allyes.cn/main/adfshow?user=21cn|www|button_r2&db=ad21cn&border=0&local=yesDocumentComplete:http://custom21cn.allyes.cn/main/adfshow?user=21cn|www|hengfu3&db=ad21cn&border=0&local=yesDocumentComplete:http://custom21cn.allyes.cn/main/adfshow?user=21cn|www|button_l1&db=ad21cn&border=0&local=yesDocumentComplete:http://custom21cn.allyes.cn/main/adfshow?user=21cn|www|hengfu4&db=ad21cn&border=0&local=yesNavigateComplete2:http://www.21cn.com/weekly/gundong/index.shtmlNavigateComplete2:http://img.vgo.21cn.com/clientv3/21cnindex/tv.htmlDocumentComplete:http://img.vgo.21cn.com/clientv3/21cnindex/tv.htmlNavigateComplete2:http://review.21cn.com/home_page_review.htmlDocumentComplete:http://www.21cn.com/weekly/gundong/index.shtmlDocumentComplete:http://review.21cn.com/home_page_review.htmlNavigateComplete2:http://finance.21cn.com/dyif/topindexv2/index.shtmlDocumentComplete:http://finance.21cn.com/dyif/topindexv2/index.shtmlDocumentComplete:http://www.21cn.com/

其实很简单每次点击都触发二次吗?那你就做个计数器

好像有个url属性可用

to 爱妹妹的哥哥:BeforeNavigate2事件不止激发两次，是14次，而且不同的网址，激发的次数也不同，你怎么做计数？BeforeNavigate2:http://www.21cn.com/BeforeNavigate2:http://custom21cn.allyes.cn/main/adfshow?user=21cn|www|button_l1&db=ad21cn&border=0&local=yesBeforeNavigate2:http://custom21cn.allyes.cn/main/adfshow?user=21cn|www|button_l2&db=ad21cn&border=0&local=yesBeforeNavigate2:http://custom21cn.allyes.cn/main/adfshow?user=21cn|www|button_r1&db=ad21cn&border=0&local=yesBeforeNavigate2:http://custom21cn.allyes.cn/main/adfshow?user=21cn|www|button_r2&db=ad21cn&border=0&local=yesBeforeNavigate2:http://custom21cn.allyes.cn/main/adfshow?user=21cn|www|hengfu1&db=ad21cn&border=0&local=yesBeforeNavigate2:http://custom21cn.allyes.cn/main/adfshow?user=21cn|www|hengfu2&db=ad21cn&border=0&local=yesBeforeNavigate2:http://custom21cn.allyes.cn/main/adfshow?user=21cn|www|hengfu3&db=ad21cn&border=0&local=yesBeforeNavigate2:http://custom21cn.allyes.cn/main/adfshow?user=21cn|www|hengfu4&db=ad21cn&border=0&local=yesBeforeNavigate2:http://finance.21cn.com/dyif/topindexv2/index.shtmlBeforeNavigate2:http://guba.finance.21cn.com/other/index_calendar_1.jspBeforeNavigate2:http://img.vgo.21cn.com/clientv3/21cnindex/tv.htmlBeforeNavigate2:http://review.21cn.com/home_page_review.htmlBeforeNavigate2:http://www.21cn.com/weekly/gundong/index.shtmlto lxw5214:我的连接就是用URL属性中提出来的，问题是我不知道如何区分哪些是用户点的，哪些是自动载入的。上面除了第一个，其他的都是自动载入的。但是用户不一定是点www.21cn.com呀，到时我怎么区分？

根据http原理来说，用户点击的应该是最先访问的也是最早触发beforenavigate2的链接。获取页面源码后，由于该页面包含（比如子框架，图片等链接），因此webbrowser就取这些子链接，再取的时候触发相应beforenavigate2事件，这些顺序反而不是固定的。

接受答案了.
