我有一个网络浏览器，我试图将其保持在最低限度以使其快速运行（我有 firefox gecko 浏览器引擎，尽管我认为这对这个问题无关紧要。）但是我想添加一件事那就是书签。现在我有很多乱七八糟的代码，但是每次点击书签按钮时我都无法创建一个新的工具条按钮。所以我所做的是添加了适当的设置和 6 个工具条按钮。现在这将我限制为 6 个书签。这真的很糟糕。我的代码在这里：

Imports System.IO

        ToolStripButton6.Text = My.Settings.mark66
        ToolStripButton6.Visible = True
    End If
  End Sub
End Class

这就是全部。但正如我之前所说，我只能添加 6 个书签。有什么办法可以添加无限数量的书签。我试过这样的事情：

Private Sub Bookmark()
  Dim mark As New ToolStripButton
  mark.DisplayStyle = Text
  mark.Parent = ToolStrip1 'This didn't work
End Sub

但如果我确实让它工作，我会放什么让它导航到那个页面？请帮忙。

我终于找到了这个问题的答案。如果有人想知道链接在哪里：

祝你今天过得愉快。

创建一个名为 favorite 的类和一个名为 favorites 的 system.collections.specialized.stringcollection 类型的设置

public class favorite
    inherits toolstripsplitbutton
    public mytitle as string
    public myurl as string
    public myimg as image
    public mybrowser as webbrowser

    public sub new(title as string, url as string, browser as webbrowser)
        mybase.new()

        mytitle = title
        myurl = url
        'create a getfavicon function - Google :)
        myimg = GetFavicon(myurl)
        mybrowser = browser
        me.text = mytitle
        me.tooltiptext = mytitle + " : " + myurl
        me.image = myimg
    end sub

    private sub Favorite_Click(sender as object, e as eventargs) handles me.click
        browser.navigate(myurl)
    end sub

然后在您的表单代码中添加一个子

public sub AddFav() handles '>>the add favorite button<<.click
    my.settings.favorites.add(webbrowser.documenttitle + "|" + webbrowser.url.tostring)
    my.settings.save()
end sub

public sub RefreshFavs()
    for each fav as string in my.settings.favorites
        dim favarray as array = fav.split(new char() {"|"c})
        dim x as new favorite(favarray(0), favarray(favarray.count - 1, webbrowser)
        mytoolstrip.items.add(x)
    next
end sub

简单解释：

AddFav() - 使用页面标题和 url 保存收藏夹

RefreshFavs() - 用“|”分割每个设置 标题和网址是分开的

类 Favorite() - 允许您添加一个拆分按钮，将链接的浏览器导航到它的 myurl 变量。

希望这可以帮助。对不起，如果它有点粗糙，我不得不从我的记忆中回忆它。
