Private Sub button1_Click(sender As Object, e As EventArgs) Handles Button1.Click

Dim stream As IO.Stream = WebRequest.Create(UrlAdress).GetResponse().GetResponseStream()

'注意urladress为你上面的网页地址。

Dim sr As StreamReader = New StreamReader(stream, System.Text.Encoding.UTF8)

Label1.Text = Regex.Match(sr.ReadToEnd, "回答采纳率").ToString

'sr。readtoend读取网页流到末尾，即使用正则表达式从网页流中提取“回答采纳率”，赋值给Label1.Text ‘没有则为空

sr.Dispose() '关闭流
