    End Sub

    Private Sub MainForm_Load(sender As Object, e As EventArgs) Handles MyBase.Load
        webBrowser.Navigate("https://www.example.com")
    End Sub

    Private Sub WebBrowser_DocumentCompleted(sender As Object, e As WebBrowserDocumentCompletedEventArgs)
        Dim htmlText As String = webBrowser.Document.Body.InnerText
        ' 在这里可以对获取到的HTML文本进行处理
        Console.WriteLine(htmlText)
    End Sub
