2.html端示例代码，
文件名为index.aspx
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="index.aspx.cs" Inherits="upload_file_lianxi.index" %><!DOCTYPE html><html xmlns="http://www.w3.org/1999/xhtml">

<body><form id="form1" runat="server" ><div><p>服务器端控件上传</p><asp:FileUpload ID="MyFileUpload" runat="server" /> <asp:Button ID="FileUploadButton" runat="server" Text="上传" onclick="FileUploadButton_Click" /></div></form>
</body>
</html>3.index.aspx.cs示例代码
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;namespace upload_file_lianxi
