我是ASPX和VB.net的新手，所以我试图从我的ASPX页面实现简单的onClick方法来打开一个新的页面，但我得到了以下错误：
Button不是asp.net的成员。
这是我的简单html页面与引导：
<%@ Page Language="vb" AutoEventWireup="false" CodeBehind="login.aspx.vb" Inherits="gabServizi.login" %>
<!DOCTYPE html>
<html>
<head>

</form>
</body>
</html>
这是vb的一部分：
Public Class login
Inherits System.Web.UI.Page
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
End Sub
Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
Response.Redirect("index.aspx")
End Sub
End Class
嗨，使用服务器端方法试试这个
Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
Server.Transfer("index.aspx", True)
End Sub
