Question

我想使用“BookmarksManager.Chrome”（NuGet包）。我已经能够使用ChromeBookmarksReader.Read阅读书签。但我需要在树中显示书签结构，而我还没有找到一种方法来获取书签ID和parentid。有谁知道如何做到这一点？ ChromeBookmarkModel似乎拥有所有信息。但是怎么用呢？无法将BookmarkFolder转换为ChromeBookmarkModel ...

最好的问候，汤姆

我建议使用Html Agility Pack代替BookmarksManager nuget。我尝试实现与您相同的功能，但使用BookmarksManager nuget没有运气。幸运的是，我能够找到一种使用Html Agility Pack显示文件夹层次结构的方法。不可否认，我的解决方案是针对WPF的，但我确定将其重写为WinForms并不是什么大不了的事。

<强> 1。使用Html Agility Pack删除所有阻止文件成为有效XML的标记，从而阻止我们正确阅读结构：

    public void OpenBookmarksFile()
    {
        string BookmarksFile_w_impeding_tags = @"your_bookmarks_file.html";
        BuildTree(treeView, XDocument.Load(Path.Combine(Directory.GetCurrentDirectory(), (DeleteTags(BookmarksFile_w_impeding_tags)))));
    }

    public string DeleteTags(string BookmarksFile_w_impeding_tags)
    {
        StreamReader BookmarkDatei = new StreamReader(BookmarksFile_w_impeding_tags);
        string content = BookmarkDatei.ReadToEnd();
        BookmarkDatei.Close();
        HtmlDocument doc_lessTags = new HtmlDocument();

        //deletes all DD Tags
        string DD = "(<DD>[a-zA-Z0-9]+[^<]+)"; //Regex-Pattern
        doc_lessTags.LoadHtml(Regex.Replace(content, DD, ""));

        //variable for each tag that could be impeding for displaying the correct hierarchy
        var metas = doc_lessTags.DocumentNode.SelectNodes("//meta");
        var titles = doc_lessTags.DocumentNode.SelectNodes("//title");
        var h1s = doc_lessTags.DocumentNode.SelectNodes("//h1");
        var dts = doc_lessTags.DocumentNode.SelectNodes("//dt");
        var ps = doc_lessTags.DocumentNode.SelectNodes("//p");
        var hrs = doc_lessTags.DocumentNode.SelectNodes("//hr");
        var dds = doc_lessTags.DocumentNode.SelectNodes("//dd");
        var aa = doc_lessTags.DocumentNode.SelectNodes("//a");
        var h3s = doc_lessTags.DocumentNode.SelectNodes("//h3");

        //delete all tags that could be impeding (comments too)
        //------------------------------------------------------------------------------------------------------------------------
        var doctype = doc_lessTags.DocumentNode.SelectSingleNode("/comment()[starts-with(.,'<!DOCTYPE')]");
        if (doctype != null)
        {
            doctype.Remove();
        }
        //------------------------------------------------------------------------------------------------------------------------
        var comments = doc_lessTags.DocumentNode.SelectSingleNode("//comment()");
        if (comments != null)
        {
            comments.Remove();
        }
        //------------------------------------------------------------------------------------------------------------------------
        foreach (var meta in metas)
        {
            meta.Remove();
        }
        //------------------------------------------------------------------------------------------------------------------------
        foreach (var title in titles)
        {
            title.Remove();
        }
        //------------------------------------------------------------------------------------------------------------------------
        foreach (var h1 in h1s)
        {
            h1.Remove();
        }
        //-----some(open tags, like DT) can not be deleted the normal way becaue they would reverse the order of our file------
        if (dts != null)
        {
            foreach (var dt in dts)
            {
                if (!dt.HasChildNodes)
                {
                    dt.ParentNode.RemoveChild(dt);
                    continue;
                }

                for (var i = dt.ChildNodes.Count - 1; i >= 0; i--)
                {
                    var child = dt.ChildNodes[i];
                    dt.ParentNode.InsertAfter(child, dt);
                }
                dt.ParentNode.RemoveChild(dt);
            }
        }
        //--------------------------------------------------------------------------------------------------------------------------------------
        if (ps != null)
        {
            foreach (var p in ps)
            {
                if (!p.HasChildNodes)
                {
                    p.ParentNode.RemoveChild(p);
                    continue;
                }

                for (var i = p.ChildNodes.Count - 1; i >= 0; i--)
                {
                    var child = p.ChildNodes[i];
                    p.ParentNode.InsertAfter(child, p);
                }
                p.ParentNode.RemoveChild(p);
            }
        }
        //--------------------------------------------------------------------------------------------------------------------------------------
        if (hrs != null)
        {
            foreach (var hr in hrs)
            {
                if (!hr.HasChildNodes)
                {
                    hr.ParentNode.RemoveChild(hr);
                    continue;
                }

                for (var i = hr.ChildNodes.Count - 1; i >= 0; i--)
                {
                    var child = hr.ChildNodes[i];
                    hr.ParentNode.InsertAfter(child, hr);
                }
                hr.ParentNode.RemoveChild(hr);
            }
        }
        //--------------------------------------------------------------------------------------------------------------------------------------
        if (dds != null)
        {
            foreach (var dd in dds)
            {
                if (!dd.HasChildNodes)
                {
                    dd.ParentNode.RemoveChild(dd);
                    continue;
                }

                for (var i = dd.ChildNodes.Count - 1; i >= 0; i--)
                {
                    var child = dd.ChildNodes[i];
                    dd.ParentNode.InsertAfter(child, dd);
                }
                dd.ParentNode.RemoveChild(dd);
            }
        }
        //------------------------------------------------------------------------------------------------------------------------

        //system partition
        string sysPart = System.IO.Path.GetPathRoot(Environment.SystemDirectory);
        //currently logged in user
        string userName = Environment.UserName;


        //after deleting all impeding tags we save the result to a new file so that we can keep our original file untouched
        string BookmarksFile_less_tags = $@"{sysPart}Users\{userName}\Desktop\bookmarks_less_tags";
        doc_lessTags.Save(BookmarksFile_less_tags);

        return BookmarksFile_less_tags;
    }

<强> 2。使用新创建的File with System.Xml;和System.Xml.Linq;填充TreeView

 public void BuildTree(TreeView treeView, XDocument doc)
    {
        TreeViewItem treeNode = new TreeViewItem
        {
            //Should be Root
            Header = doc.Root.Name.LocalName,
            IsExpanded = true
        };
        treeView.Items.Add(treeNode);
        BuildNodes(treeNode, doc.Root);
    }

    public void BuildNodes(TreeViewItem treeNode, XElement element)
    {
        foreach (XNode child in element.Nodes())
        {
            switch (child.NodeType)
            {
                case XmlNodeType.Element:
                    XElement childElement = child as XElement;
                    XElement prev = child.PreviousNode as XElement;
                    if(childElement.Name == "dl" && prev.Name == "h3")
                    { 

                        TreeViewItem childTreeNode = new TreeViewItem
                        {
                            //because only the dl nodes have child nodes we want 
                            //to display the dl nodes with the inner text of thier respective previous node
                            Header = prev.Value
                        };

                        treeNode.Items.Add(childTreeNode);
                        BuildNodes(childTreeNode, childElement);
                    }
                    break;
                case XmlNodeType.Text:
                    XText childText = child as XText;
                    treeNode.Items.Add(new TreeViewItem { Header = childText.Value, });
                    break;
            }
        }
    }

if you don't add any icons it will look something like this..

Answer 2

文档不是很详细。

但是，代码足够小，可以（部分）替换文档：

public class BookmarkFolder : Collection<IBookmarkItem>, IBookmarkFolder

换句话说：您自己获取的每个文件夹包含其子项（文件夹和链接）的集合：

using (var file = File.OpenRead(path)) {
    var reader = new NetscapeBookmarksReader();
    var bookmarks = reader.Read(file);
    foreach (var item in bookmarks) {
        if (item is BookmarkFolder) {
        } else if (item is BookmarkLink) {
        }
        ....
