用HttpFileCollection实现多文件上传的例子

注意：页面Form的属性一定要设为enctype="multipart/form-data"

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

<!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>Untitled Page</title>
</head>
<body>
    <form id="form1" runat="server" enctype="multipart/form-data">
    <div>
    
        <input id="File1" type="file" name="File1" />
        <br />
        <input id="File2" type="file" name="File2" />
        <br />
        <asp:Button 
            ID="Button1" runat="server" Text="Button" onclick="Button1_Click" />
    
    </div>
    </form>
</body>
</html>

using System;
using System.IO;
using System.Collections;
using System.Configuration;
using System.Data;
using System.Web;
using System.Web.UI;
using System.Web.UI.HtmlControls;
using System.Web.UI.WebControls;


namespace NetSamples
{
    public partial class upLoadFiles : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {

        }

        protected void Button1_Click(object sender, EventArgs e)
        {
            if (Request.Files != null)
            {
                HttpFileCollection files = Request.Files;
                string fileName;
                for(int i = 0;i < files.Count;i++)
                {
                    if (files[i].ContentLength <= 0)
                    {
                        continue;
                    }
                    fileName = Path.GetFileName(files[i].FileName);
                    files[i].SaveAs(Request.MapPath(@"../files/" + fileName));
                }
            }
        }
    }
}

 

获取文件扩展名：System.IO.Path.GetExtension(path);
