vb.net 教程 12-2 HtmlDocument类 2

从本节开始，将对HtmlDocument类的一些属性和方法做讲解。

窗体设计界面如下：

转到按钮代码如下：

    Private Sub btnGoto_Click(sender As Object, e As EventArgs) Handles btnGoto.Click        wbMain.Navigate(txtGotoUrl.Text)    End Sub

当wbMain载入网页后，就可以获得网页相关信息了：

    Private Sub btnInfo_Click(sender As Object, e As EventArgs) Handles btnInfo.Click        Dim htmlInfo As String = ""        Dim document As HtmlDocument        document = wbMain.Document        htmlInfo &= "网页背景色：" & document.BackColor.ToString & ControlChars.CrLf        htmlInfo &= "网页前景色：" & document.ForeColor.ToString & ControlChars.CrLf        htmlInfo &= "网页标题：" & document.Title & ControlChars.CrLf        htmlInfo &= "网址：" & document.Url.ToString & ControlChars.CrLf        htmlInfo &= "Cookie：" & document.Cookie & ControlChars.CrLf        htmlInfo &= "所在域：" & document.Domain & ControlChars.CrLf        htmlInfo &= "网页编码：" & document.Encoding & ControlChars.CrLf        htmlInfo &= "链接颜色：" & document.LinkColor.ToString & ControlChars.CrLf        htmlInfo &= "链接访问颜色：" & document.VisitedLinkColor.ToString & ControlChars.CrLf        txtInfo.Text = htmlInfo    End Sub

运行时如下图：
