uploadify批量上傳文件完整使用教程，供大家參考，具體內容如下

1.首先準備uploadify的js文件，網上一搜一大堆

2.上傳頁面UpFilePage.aspx

關鍵代碼：

html xmlns="http://www.w3.org/1999/xhtml">
head runat="server">
meta http-equiv="Content-Type" content="text/html; charset=utf-8"/>
title>上傳文件/title>
link href="/jquery.uploadify/uploadify.css" rel="stylesheet" />

script type="text/javascript" src="/jquery.uploadify/jquery-1.8.3.min.js">/script>
script src="/jquery.uploadify/swfobject.js" charset="utf-8">/script>
script src="/jquery.uploadify/jquery.uploadify.v2.1.0.js">/script>
style type="text/css">
#fileSave { padding-left:5px; padding-right:5px;}

#uploadifyUploader { position:absolute; opacity:0;}
.uploadify-button{ height: 30px; line-height: 30px; width: 109px; text-align:center; border:0px; margin-bottom:5px; background:#ff6600; color:#fff;}

script type="text/javascript">
var fileCount = 0;
$(document).ready(function () {
fileCount = $("#fileSave>div.uploadifyQueueItem").length;
$("input[name='radPhone']:eq(0)").attr("checked", "checked");
$("#uploadify").uploadify({
'uploader': '/jquery.uploadify/uploadify.swf',//uploadify.swf 文件的相對路徑

后臺的GetFile()方法：

/// summary>
/// 獲取cookie附件信息
/// /summary>
/// returns>/returns>
protected string GetFile()
{
#region 獲取cookie附件信息

StringBuilder strHtml = new StringBuilder();
HttpCookie fileCookie = Request.Cookies["FileCookie"];
if (fileCookie != null)
{
string[] fileArray = new string[1];
if (fileCookie.Value.Contains("|"))
fileArray = fileCookie.Value.Split('|');
else
fileArray[0] = fileCookie.Value;
foreach (string objFile in fileArray)
{
if (!string.IsNullOrEmpty(objFile)  objFile.Contains(","))
{
string[] file = objFile.Split(',');
strHtml.Append(@"div class='uploadifyQueueItem'>");
strHtml.Append(@"div class='cancel'>");
strHtml.Append("a href='javascript:deleteFile(\"" + file[1] + "\")'>/a>");
//strHtml.Append(@"img src='/Scripts/jquery.uploadify/cancel.png' border='0'>");
strHtml.Append(@"/div>");
strHtml.Append(@"span class='fileName'>" + HttpUtility.UrlDecode(file[0]) + "/span>span class='percentage'> - 100%/span>div class='uploadifyProgress'>");
strHtml.Append(@"div class='uploadifyProgressBar' style='width: 100%;'>");
strHtml.Append(@"/div>");
strHtml.Append(@"/div>");
strHtml.Append(@"/div>");
}
}
}
return strHtml.ToString();
#endregion
}

3.UploadAction文件夾下的一般處理程序：

public void ProcessRequest(HttpContext context)
{
context.Response.ContentType = "text/plain";
string operate = context.Request["operate"];
if (operate == "deleteFile")
{
#region 刪除文件附件信息
//獲取文件路徑
string filePath = context.Server.MapPath(context.Request["file"]);
//判斷文件是否存在
if (File.Exists(filePath))
File.Delete(filePath);//刪除文件
//獲取附件cookie信息
HttpCookie fileCookie = context.Request.Cookies["FileCookie"];
string[] fileArray = new string[1];
if (fileCookie != null)
{
filePath = filePath.Remove(0, filePath.IndexOf("upfiles")).Replace("\\", "/");
if (fileCookie.Value.Contains("|"))
fileArray = fileCookie.Value.Split('|');
else
fileArray[0] = fileCookie.Value;
string strFile = "";
for (int i = 0; i  fileArray.Length; i++)
{
if (!fileArray[i].Contains(filePath))
strFile += fileArray[i] + "|";
}
if (strFile.Contains("|"))
strFile = strFile.Remove(strFile.Length - 1);
fileCookie.Value = strFile;
fileCookie.Expires = DateTime.Now.AddDays(1);
fileCookie.HttpOnly = true;
context.Response.AppendCookie(fileCookie);


StringBuilder strHtml = new StringBuilder();
if (fileCookie.Value.Contains("|"))
fileArray = fileCookie.Value.Split('|');
else
fileArray[0] = fileCookie.Value;
foreach (string objFile in fileArray)
{
if (!string.IsNullOrEmpty(objFile)  objFile.Contains(","))
{
string[] file = objFile.Split(',');
strHtml.Append(@"div class='uploadifyQueueItem'>");
strHtml.Append(@"div class='cancel'>");
strHtml.Append("a href='javascript:deleteFile(\"" + file[1] + "\")'>/a>");
//strHtml.Append(@"img src='/Scripts/jquery.uploadify-v2.1.0/cancel.png' border='0'>");
strHtml.Append(@"/div>");
strHtml.Append(@"span class='fileName'>" + HttpUtility.UrlDecode(file[0]) + "/span>span class='percentage'> - 100%/span>div class='uploadifyProgress'>");
strHtml.Append(@"div class='uploadifyProgressBar' style='width: 100%;'>");
strHtml.Append(@"/div>");
strHtml.Append(@"/div>");
strHtml.Append(@"/div>");
}
}
context.Response.Write(strHtml.ToString());
}
#endregion
}
else if (operate == "GetFile")
{
#region 獲取上傳的附件并展示
StringBuilder strHtml = new StringBuilder();
HttpCookie fileCookie = context.Request.Cookies["FileCookie"];
if (fileCookie != null)
{
string[] fileArray = new string[1];
if (fileCookie.Value.Contains("|"))
fileArray = fileCookie.Value.Split('|');
else
fileArray[0] = fileCookie.Value;
foreach (string objFile in fileArray)
{
if (!string.IsNullOrEmpty(objFile)  objFile.Contains(","))
{
string[] file = objFile.Split(',');
strHtml.Append(@"div class='uploadifyQueueItem'>");
strHtml.Append(@"div class='cancel'>");
strHtml.Append("a href='javascript:deleteFile(\"" + file[1] + "\")'>");
//strHtml.Append(@"img src='/Scripts/jquery.uploadify-v2.1.0/cancel.png' border='0'>/a>");
strHtml.Append(@"/div>");
strHtml.Append(@"span class='fileName'>" + HttpUtility.UrlDecode(file[0]) + "/span>span class='percentage'> - 100%/span>div class='uploadifyProgress'>");
strHtml.Append(@"div class='uploadifyProgressBar' style='width: 100%;'>");
strHtml.Append(@"/div>");
strHtml.Append(@"/div>");
strHtml.Append(@"/div>");
}
}
}
context.Response.Write(strHtml.ToString());
#endregion
}
}

4.上傳文件uploadHandler.ashx一般處理程序代碼，文件上傳路徑可以根據劇情需要自由設定：

public void ProcessRequest(HttpContext context)
{
context.Response.ContentType = "text/plain";

HttpCookie fileCookie = context.Request.Cookies["FileCookie"];
if (fileCookie != null)
{
string[] fileArray = new string[1];
if (fileCookie.Value.Contains("|"))
fileArray = fileCookie.Value.Split('|');
if (fileArray.Length >= 5)
return;
}
else
{
fileCookie = new HttpCookie("FileCookie");
fileCookie.Value = "";
context.Response.Cookies.Add(fileCookie);
}

String aspxUrl = context.Request.Path.Substring(0, context.Request.Path.LastIndexOf("/") + 1);

//文件保存目錄路徑
String savePath = "/upfiles/";

//文件保存目錄URL
String saveUrl = "/upfiles/";

//if (context.Request.Cookies["Member"] != null)
//{
// savePath += context.Request.Cookies["Member"]["MemberId"] + "/";
// saveUrl += context.Request.Cookies["Member"]["MemberId"] + "/";
//}
string Member = Guid.NewGuid().ToString().Trim().Replace("-", "");
savePath += Member + "/";
saveUrl += Member + "/";

//定義允許上傳的文件擴展名
/*Hashtable extTable = new Hashtable();
extTable.Add("image", "gif,jpg,jpeg,png,bmp");
extTable.Add("flash", "swf,flv");
extTable.Add("media", "swf,flv,mp3,wav,wma,wmv,mid,avi,mpg,asf,rm,rmvb,mp4");
extTable.Add("file", "doc,docx,xls,xlsx,ppt,htm,html,txt,zip,rar,gz,bz2,swf,flv,mp3,wav,wma,wmv,mid,avi,mpg,asf,rm,rmvb,mp4,wps");*/

//最大文件大小
int maxSize = 5242880;

HttpPostedFile imgFile = context.Request.Files["imgFile"];
/*if (imgFile == null)
{
showError("請選擇文件。");
}*/

String dirPath = context.Server.MapPath(savePath);
if (!Directory.Exists(dirPath))
{
Directory.CreateDirectory(dirPath);
//showError("上傳目錄不存在。");
}

String dirName = context.Request.QueryString["dir"];
if (String.IsNullOrEmpty(dirName))
{
dirName = "file";
}
/*if (!extTable.ContainsKey(dirName))
{
showError("目錄名不正確。");
}*/

String fileName = imgFile.FileName;
String fileExt = Path.GetExtension(fileName).ToLower();


/*if (String.IsNullOrEmpty(fileExt) || Array.IndexOf(((String)extTable[dirName]).Split(','), fileExt.Substring(1).ToLower()) == -1)
{
showError("上傳文件擴展名是不允許的擴展名。\n只允許" + ((String)extTable[dirName]) + "格式。");
}
if (dirName.Contains("image"))
{
if (imgFile.InputStream == null || imgFile.InputStream.Length > maxSize)
{
showError("上傳文件超過5M大小限制。");
}
}*/

//創建文件夾
dirPath += dirName + "/";
saveUrl += dirName + "/";
if (!Directory.Exists(dirPath))
{
Directory.CreateDirectory(dirPath);
}
String ymd = DateTime.Now.ToString("yyyyMMdd", DateTimeFormatInfo.InvariantInfo);
dirPath += ymd + "/";
saveUrl += ymd + "/";
if (!Directory.Exists(dirPath))
{
Directory.CreateDirectory(dirPath);
}

String newFileName = DateTime.Now.ToString("yyyyMMddHHmmss_ffff", DateTimeFormatInfo.InvariantInfo) + fileExt;
String filePath = dirPath + newFileName;

imgFile.SaveAs(filePath);

String fileUrl = saveUrl + newFileName;

/*Hashtable hash = new Hashtable();
hash["error"] = 0;
hash["url"] = fileUrl;
context.Response.AddHeader("Content-Type", "text/html; charset=UTF-8");
context.Response.Write(JsonMapper.ToJson(hash));
context.Response.End();*/

if (fileCookie != null)
{
string strFile = fileCookie.Value;
if (!string.IsNullOrEmpty(strFile))
strFile = strFile + "|" + HttpUtility.UrlEncode(fileName) + "," + fileUrl;
else
strFile = HttpUtility.UrlEncode(fileName) + "," + fileUrl;
fileCookie.Value = strFile;
fileCookie.Expires = DateTime.Now.AddDays(1);
fileCookie.HttpOnly = true;
context.Response.AppendCookie(fileCookie);
}
context.Response.Write("1");
context.Response.End();
}
