在C＃Winforms中的同一表单上从一个WebBrowser导航到另一个WebBrowser

我有一个名为webbrowser3的webbrowser，它正在显示其html文件内容的链接。示例： - 一个WebBrowser（WebBrowser3）显示目录（TOC），我希望在哪个章节或它的一部分上单击，它在另一个WebBrowser（WebBrowser2）上显示其内容，该内容以相同的WebBrowser3形式放置。我制作了目录（TOC），但是当单击任何章节时，它在放置TOC的同一WebBrowser（WebBrowser3）上显示其内容。我已经通过以下方式尝试了它，但没有显示所需的结果。

  string toc = File.ReadAllText(StaticClass.ZipFilePath + "\OEBPS\IDSBooktoc.html");
         webBrowser3.DocumentText =toc;

我没有得到完全应该做的事情...这是我的html

</html>

private string tocpage = "IDSBooktoc.html";
private string outpage = "IDSBookout.html";
private void Form1_Load(object sender, EventArgs e)
{
    //load toc, only for parsing
    webBrowser2.Visible = false;
    webBrowser2.DocumentCompleted += new WebBrowserDocumentCompletedEventHandler(webBrowser2_DocumentCompleted);
    webBrowser2.DocumentText = File.ReadAllText(tocpage);
}
void webBrowser2_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)
{
    //Populate treeview
    foreach (HtmlElement ele in webBrowser2.Document.GetElementsByTagName("a"))
    {
        treeView1.Nodes.Add(ele.GetAttribute("href"), ele.InnerText);
    }
    //detach event
    webBrowser2.DocumentCompleted -= new WebBrowserDocumentCompletedEventHandler(webBrowser2_DocumentCompleted);
    //change webbrowser2 source
    webBrowser2.DocumentText = File.ReadAllText(outpage);
}
private void treeView1_AfterSelect(object sender, TreeViewEventArgs e)
{
    string selected = e.Node.Name; //IDSBookout.html#NCXGen0
    string bookmark = selected.Substring(selected.IndexOf("#") + 1);
    webBrowser2.Document.GetElementById(bookmark).ScrollIntoView(true);
    webBrowser2.Visible = true;
}

这是我表单的完整代码，我使用了私有变量" nexturl"（链接是相同的，仅更改书签）。

private Uri nexturl = null;
private void Event_Navigating(object sender, WebBrowserNavigatingEventArgs e)
{
    e.Cancel = true;
    nexturl = e.Url;
    webBrowser2.Navigate(new Uri("about:blank"));//necessary, the webbrowser2 don't see that the url has changed
}
private void webBrowser3_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)
{
    webBrowser3.Navigating += new WebBrowserNavigatingEventHandler(Event_Navigating);
    webBrowser2.DocumentCompleted += new WebBrowserDocumentCompletedEventHandler(webBrowser2_DocumentCompleted);
}
void webBrowser2_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)
{
    if (nexturl != null)
    {
        webBrowser2.Navigate(nexturl);
        nexturl = null;
    }
}
private void Form1_Load(object sender, EventArgs e)
{
    webBrowser3.DocumentCompleted += new WebBrowserDocumentCompletedEventHandler(webBrowser3_DocumentCompleted);
    webBrowser3.Navigate(new Uri("file://" + AppDomain.CurrentDomain.BaseDirectory + "IDSBooktoc.html"));
}

我的代码的差异是您不使用URL来加载页面，而是在WebBrowser2和WebBrowser3中直接设置HTML。

以这种方式尝试：

private string tocpage = "IDSBooktoc.html";
private string outpage = "IDSBookout.html";
private void Form1_Load(object sender, EventArgs e)
{
    webBrowser3.DocumentText = File.ReadAllText(tocpage);
    webBrowser2.DocumentText = File.ReadAllText(outpage);
    webBrowser3.Navigating += new WebBrowserNavigatingEventHandler(webBrowser3_Navigating);
}
private void webBrowser3_Navigating(object sender, WebBrowserNavigatingEventArgs e)
{
    e.Cancel = true;
    //scroll webbrowser2
    string bookmark = e.Url.Fragment.Replace("#", "");
    webBrowser2.Document.GetElementById(bookmark).ScrollIntoView(true);
}
