1. 需要一个html入口：asp_net_upload_demo.html
<h3>ASPX file upload demo</h3> <iframe height="40" width="700" src="Uploadfile.aspx"> </iframe>
2.Uploadfile.aspx的内容为：
<!--
Usage: visit `asp_net_upload_demo.html`
-->
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Uploadfile.aspx.cs" Inherits="Uploadfile" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title>File Upload Control</title>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:FileUpload runat="server" ID="fuSample" />
<asp:Button runat="server" ID="btnUpload" Text="Upload"
onclick="btnUpload_Click" />
<asp:Label runat="server" ID="lblMessage" Text=""></asp:Label>
</div>
</form>
</body>
</html>
3. Uploadfile.aspx.cs
/*
* Usage:
* please change the Server.MapPath parameter as your file upload folder
* default is: "./data"
* visit `asp_net_upload_demo.html`
*
* */
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
public partial class Uploadfile : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
}
protected void btnUpload_Click(object sender, EventArgs e)
{
//Files is folder Name
fuSample.SaveAs(Server.MapPath("/data") + "//" + fuSample.FileName);
lblMessage.Text = "File Successfully Uploaded";
}
}
把这三个文件放到iis的文件夹下面，就可以了：
