最近工作比较忙，好长时间都没有到我的博客里来看看了。前天帮我兄弟解决了一个多文件上传的问题。供大家参考

前台代码如下

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

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<title>上传多文件</title>

function addFileControl()

{

var str = '<INPUT type="file" NAME="File">'

document.getElementById('FileCollection').insertAdjacentHTML("beforeEnd",str)

}

</script>

</head>

<body>

<div>

<asp:label id="Title" Runat="server"></asp:label>

</p>

<asp:button id="Upload" Runat="server" Text="上传" Width="56px" OnClick="Upload_Click"></asp:button><input style="WIDTH: 56px; HEIGHT: 24px" onclick="this.form.reset()" type="button" value="重置"/>

</p>

<p align="center"><asp:label id="strStatus" runat="server" BorderColor="White" BorderStyle="None" Width="500px"

Font-Size="9pt" Font-Bold="True" Font-Names="宋体"></asp:label></p>

</div>

</form>

</body>

</html>

.cs代码如下：

using System;

using System.Data;

using System.Configuration;

using System.Collections;

using System.Web;

using System.Web.Security;

using System.Web.UI;

using System.Web.UI.WebControls;

using System.Web.UI.WebControls.WebParts;

using System.Web.UI.HtmlControls;

public partial class upMoreFile : System.Web.UI.Page

{

protected void Page_Load(object sender, EventArgs e)

{

Title.Text = "<h3>多文件上传</h3>";

Upload.Text = "开始上传";

}

/// <summary>

/// 方法名：upMoreFile()

/// 功能描述:循环表单，多文件上传

/// 调用方法：bool var=upMoreFile()

/// </summary>

/// <returns>bool</returns>

protected bool upMorefile()

{

//遍历File表单元素

System.Web.HttpFileCollection files = System.Web.HttpContext.Current.Request.Files;

//状态信息

System.Text.StringBuilder strMsg = new System.Text.StringBuilder("上传的文件信息分别为：<hr color=red>");

int fileCount;

int filecount = files.Count;

try

{

for (fileCount = 0; fileCount < files.Count; fileCount++)

{

//定义访问客户端上传文件的对象

System.Web.HttpPostedFile postedFile = files[fileCount];

string fileName, fileExtension;

//取得上传得文件名

fileName = System.IO.Path.GetFileName(postedFile.FileName);

if (fileName != String.Empty)

{

//取得文件的扩展名

fileExtension = System.IO.Path.GetExtension(fileName);

//上传的文件信息

strMsg.Append("上传的文件类型：" + postedFile.ContentType.ToString() + "<br>");

strMsg.Append("客户端文件地址：" + postedFile.FileName + "<br>");

strMsg.Append("上传文件的文件名：" + fileName + "<br>");

strMsg.Append("上传文件的扩展名：" + fileExtension + "<br><hr color=red>");

//保存到指定的文件夹

postedFile.SaveAs(Server.MapPath("upedFile/") + fileName);

}

strStatus.Text = strMsg.ToString();

return true;

}

catch (System.Exception error)

{

strStatus.Text = error.Message;

return false;

}

protected void Upload_Click(object sender, EventArgs e)

{

upMorefile();

}

效果如下：
