c# - 点击网页链接

Question

首先，抱歉我的英语不好。

问题很简单。我想用 C#(Windows 窗体)单击链接

这是我使用的代码:

int number_to_show = Convert.ToInt32(listView1_new_message.SelectedItems[0].SubItems[4].Text);
            int a_to_click = (number_to_show * 5) + 2;
            string titel_of_message = listView1_new_message.SelectedItems[0].SubItems[1].Text;
            HtmlWindow SContentFrame = webBrowser1.Document.Window.Frames[1];
            HtmlWindow Frame_A = SContentFrame.Document.Window.Frames[2];
            HtmlElementCollection links = Frame_A.Document.GetElementsByTagName("b");
            int link_counter = 0;
            foreach (HtmlElement link in links) {
                if (link_counter == a_to_click && link.InnerText.Equals(titel_of_message)) {
                    link.InvokeMember("Click");
                }
                link_counter++;
            }

它想要点击(我看到它在调试中发生，当我点击一个消息框时，消息框出现)，但网页没有反应。

这是网页上 标签中的 html 代码:

<b><a href="" onclick="OnPhoenixRead('/mail/MessageRead?sid=7613BA4BF987D55FD171D53FAA24A259C7FDE435&amp;userid=*******&amp;seq=+Q&amp;auth=+A&amp;srcfolder=INBOX&amp;uid=3291&amp;srch=0&amp;style=default'); return false">Doorgest: testing 2</a></b>

所以它不会以某种方式点击文本...(或不会激活 onclick 事件处理程序)

如何使程序按预期运行？

提前致谢:D废话

Answer 1

改变说

的行

HtmlElementCollection links = Frame_A.Document.GetElementsByTagName("b");

到

HtmlElementCollection links = Frame_A.Document.GetElementsByTagName("a");

您将链接设置为等于所有带有粗体标记的元素。因为链接在粗体标签内，所以 innertext 条件通过。然后你试图点击一个粗体标签，这显然什么都不做。
