virtual path change

Question

I want to change Virtual Path(The path is out of project means local system or Server.) of the file Which is save on the folder in asp.net.

Code is

DataTable dtFiles =  
    GetFilesInDirectory(HttpContext.Current.Server.MapPath(UPLOADFOLDER));
gv.DataSource = dtFiles;
gv.DataBind();

if (dtFiles != null && dtFiles.Rows.Count > 0)
{
    double totalSize = Convert.ToDouble(dtFiles.Compute("SUM(Size)", ""));
    if (totalSize > 0) lblTotalSize.Text = CalculateFileSize(totalSize);
}

private static string UPLOADFOLDER = "D:/Uploads";

And the error show "D:/Uploads is not a valid virtual path.".

If you want to get the files in a directory and you know the full path, then you don't need to use Server.MapPath(). Just use the path.

Incidentally, the path delimiter is incorrect in your code. The string "D:/Uploads" should be @"D:\Uploads" (note the leading @ sign to denote a string that should be treated literally and not escaped).

Of course. You're telling your server to map path that is completely off the IIS. How is it supposed to do? If you're using a web application, try to avoid such ideas completely. Even though it is possible, it isn't a good idea because of security issues you can run into.
