在asp.net利用jquery实现多文件上传

具体方式是：

首先需要有jquery.js 其次要有jquery.MultiFile.js这两个文件

然后前台代码如下:

<%@ Page Language="C#" AutoEventWireup="true"  CodeFile="Default.aspx.cs" Inherits="_Default" %>

<!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></title>

    <script src="jquery.js" type="text/javascript"></script>

    <script src="jquery.MultiFile.js" type="text/javascript"></script>
</head>
<body>
    <form id="form1" runat="server">
    <div>

        <asp:FileUpload ID="FileUpload1" runat="server" class="multi" />
        <asp:Button ID="Button1" runat="server" Text="上传" onclick="Button1_Click"
            Width="70px" />

    </div>
    </form>
</body>
</html>

后台代码如下：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;

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

    }
    protected void Button1_Click(object sender, EventArgs e)
    {
        try
        {
            HttpFileCollection hfc = Request.Files;
            for (int i = 0; i < hfc.Count; i++)
            {
                HttpPostedFile hpf=hfc[i];
                if (hpf.ContentLength > 0)
                {
                    hpf.SaveAs(Server.MapPath("Files")+"\\"+System.IO.Path.GetFileName(hpf.FileName));
                    Response.Write("文件："+hpf.FileName+"大小："+hpf.ContentLength+"类型："+hpf.ContentType+"上传成功！<br>");
                }
            }
        }
        catch { }
    }
}
