在ASP.NET中上传文件必须使用FileUpload控件一个个上传吗？

我的需要是客户端在本地目录中有一组文件需要上传，系统需要对每个文件进行上传，难道要客户一个文件一个文件的选择，然后分别上传吗？那效率太低了吧。有什么办法可以批量上传？各位有办法的帮帮我。

可以多个上传但是必须建立多个FileUpload 控件,一个控件传一个
需要在页面显示多个FileUplooad控件吗？手工代码创建还是设计时创建？手工代码如何创建？请楼上赐教，谢谢！
我试了一下，那个fileupload控件无法设置.PostedFile .FileName属性，是只读的，我如何设置它，以循环上传多个文件？
fileupload的.PostedFile .FileName属性都是只读的,那你就读取它好了，把读取出来的路径放入数组中，循环上传到服务器,或者你选择第三方控件
用第三方空间吧，大批量上传附件AspNetUpload，从网上搜一下吧，AspNetUpload.dll
研究一下WebClient类所提供的方法。
现在很多网站采用的多附件上传的方式一般是：1、你添加一个文件，然后点击继续添加，然后再继续添加，最后一起上传。2、页面一打开就是5个FileUpload 控件，然后可以一次上传1-5个。如果你要上传多个，也可以去本地文件夹读取你的文件，然后批量上传。
不用  你直接上网上下载 flv文件上传。
里面有一个专门上传flv视频文件的控件，是别人先做好的可以批量上传，还可以看到进度条，很实用！
  等等一会我给你找找下载地址

这个地址就是你把代码下载下来以后改良一下就可以用了。很方便，我就那么用的
上传压缩文件，上传后，在服务器端解压缩
有个类：SharpZipLib
你去搜索一下
好像.net自带也有解压缩的类库了
System.IO.Compression
但是我没用过
