Getting (The name 'file' does not exist in the current context) message

Question

UPDATE 1:

Here is the full code behind from the downloaded example, unedited:

using System;
using System.IO;
using System.Configuration;
using System.Data;
using System.Linq;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.HtmlControls;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Xml.Linq;

public partial class _Default : System.Web.UI.Page 
{
    protected void Page_Load(object sender, EventArgs e)
    {
        String UpPath;
        UpPath = "C:\\UploadedUserFiles";

        if (!Directory.Exists(UpPath))
        {
            Directory.CreateDirectory("C:\\UploadedUserFiles\\");
        }
    }
    protected void btnSubmit_Click(object sender, EventArgs e)
    {
        HttpFileCollection uploads = HttpContext.Current.Request.Files;
        for (int i = 0; i < uploads.Count; i++)
        {
            HttpPostedFile upload = file;

            if (upload.ContentLength == 0)
                continue;

            string c = System.IO.Path.GetFileName(upload.FileName); // We don't need the path, just the name.

        try
            {
            upload.SaveAs("C:\\UploadedUserFiles\\" + c);
            Span1.InnerHtml = "Upload(s) Successful.";
            }
        catch(Exception Exp)
            {
                Span1.InnerHtml = "Upload(s) FAILED.";
            }
        }
    }
}

ORIGINAL QUESTION:

I've just downloaded a "file uploading" example from www.asp.net:

Link to tutorial: http://www.asp.net/web-forms/videos/how-do-i/how-do-i-multiple-file-uploads-in-aspnet-2 Link to download: http://download.microsoft.com/download/8/6/9/869ff08a-1e39-4bab-a303-f7dcedc52427/CS-ASP-MultiFileUpload-CS.zip

and copied the files to my webserver after extracting them.

When I navigate to http://server/uploader/Default.aspx

It creates the folder in the servers c drive successfully, but on the web browser I get the following error:

Server Error in '/' Application.

Anyone know why this is happening?

Post the code of the whole method. Where do you declare the file variable? — Oded

Probably you should be getting the specific Item from the uploaded files collection HttpPostedFile upload = uploads.Item[i]; — Lloyd

You are addressing an undeclared local variable file, you should be retrieving the HttpPostedFile from the uploads "Items" collection using the Item index;

HttpPostedFile upload = uploads[i];

It seems a bug on the sample code. Try replacing this

HttpPostedFile upload = file

by

HttpPostedFile upload = uploads[i]

Along with "Default.aspx" and "Default.aspx.cs", you need "Default.aspx.Designer.cs" File. As all the controls are defined with its style in "Designer" file.
