asp.net新手入门脚本问题，求解答，急急急！！！。。

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="WebForm3.aspx.cs" Inherits="WebApplication4.WebForm3" %>

Sub submit( sender as Object ,e as EventArgs ) lbl1.Text="Your name is " & txt1.Text End Sub

<!DOCTYPE html>

输出了错误

源错误:

行 2:

行 3: 行 4: Sub submit( sender as Object ,e as EventArgs ) 行 5: lbl1.Text="Your name is " & txt1.Text 行 6: End Sub 。。。

1)代码要放到WebForm3.aspx.cs中，WebForm3.aspx是页面设计。
2)既然是C#，你放一段VB.Net代码算什么意思？
