I don't know if this can help you, but you can use the <code>FileUpload</code> Class in the namespace <code>System.Web.UI.WebControls</code>.

You can check MSDN:

1) Create an ASPX page with upload INPUT. 

2) Let the user upload the file

3) Get the ASP.NET uploaded file and write the binary streams to a file and also Register the file to a database as well

4) Finish the request but before doing that spawn a background thread to process the file

5) You need a separate cleanup operation fro those files that were registered but failed to be processed for whatever reason.

blocks|key|1289599|text|最快的解决方案-如果您的文件处理将在脚本超时之前完成，并且您乐于让用户在此期间等待：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1289600|将您网站上的虚拟目录映射到您的上传文件夹-在我们的网站上，我们将所有web服务器上的/~+upload+/映射到DMZ中的文件服务器上的开放共享。|1289601|然后在页面代码隐藏中使用类似下面这样的代码|1289602|protected+void+ProcessFilesButton_Click(object+sender,+EventArgs+e)+{

}|code-block|syntax|javascript|1289603|更复杂的解决方案包括派生一个后台线程(或单独的Windows服务或计划任务)来处理文件处理，然后返回“请稍候...”然后在代码隐藏中查询队列中文件的状态，并在每个文件的处理完成时报告它们。|1289604|entityMap^0|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|O|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|P|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|Q|8|@]|9|@]|A|$]]|$1|F|3|G|5|H|7|R|8|@]|9|@]|A|$I|J]]|$1|K|3|L|5|6|7|S|8|@]|9|@]|A|$]]|$1|M|3|-4|5|6|7|T|8|@]|9|@]|A|$]]]|N|$]]

Quickest solution - if your file processing will complete before the script timeout, and you're happy to have the user wait while it happens:

Map a virtual directory on your website to your upload folder - on our sites, we have /~upload/ on all our web servers mapped to an open share on a fileserver in our DMZ.

Then use code something like this in your page code-behind

<pre><code>protected void ProcessFilesButton_Click(object sender, EventArgs e) {
 string uploadRootPath = Server.MapPath("~/upload/"); 

 foreach(var uploadedFile in Request.Files) {

 // might want to use a GUID filename here instead
 // to avoid risk of filename conflicts.
 string bareFileName = Path.GetFileName(uploadedFile.FileName);
 string fullFilePath = Path.Combine(uploadRootPath, bareFileName);
 uploadedFile.SaveAs(fullFilePath);
 myMagicFileProcessor.ProcessFile(fullFilePath);
 }
 MyLabel.Text = String.Format("{0} files processed", Request.Files.Count);
}
</code></pre>

More complex solutions would involve spawning a background thread (or a separate Windows service or scheduled task) to handle the file processing, and then returning a "Please Wait..." page with a meta-refresh on it, that will redraw the page every, say, 10 seconds, and then in the code-behind you query the status of the files in the queue and report on them as processing completes for each one.

I'm programming in ASP.NET 3.5.

I need to process a file that has to be uploaded by a user. The file is in a specific format. Basically, I need to take the information in the file, parse it, and insert it into a SQL db. I have no problem doing that, but I was wondering how to do this from a web site. 

I think I want to create a share that the user will have access to, have the user upload the file onto the share, and upon upload, save a record into the DB with the full UNC path. In the site, process the file with that UNC path, then move the file to some "processed" folder.

Has anyone done something like this? Is there any "standard" way of doing things similar to this?

Thanks.
