Hi everyone,

Please excuse my lack of knowledge, I am a beginner at best.

I have an application that allows users to upload and download files. I can upload the file to a remote server and display contents of the folder no problem. My problem arises when I try to download, in particular when I try create the correct path. Here is my download code:

What I have tried:

<pre>  public FileResult Download(string ImageName)
        {
            var IdSes = Session["IdSes"];
           string FileVirtualPath= "/Da-app01/Data/Tracker/uploads/" + IdSes +"/"+ ImageName;

            return File(FileVirtualPath, "application/force-download", Path.GetFileName(FileVirtualPath));
        }

When I try download a file I get this error:

[DirectoryNotFoundException: Could not find a part of the path 'C:\Users\G\Desktop\application\Da-app01\Data\Tracker\uploads\33\test1.pdf'.]

The problem is the path I need is

Quote:
Da-app01\Data\Tracker\uploads\33\test1.pdf

Where does

Quote:
C:\Users\G\Desktop\application

come from? Can I remove it somehow?

Struggling Here! Any help to understand would be appreciated!

Your variable FileVirtualPath, in the eyes of MVC application, is a relative path so your application is apparently in c:\users\g\desktop\application directory so it is concatinating your file location with where it is locally.

In order for the file to download correctly, if it is stored locally on your computer, it has to utilize the full path of where the file is located. So your file isn't located locally on your computer at Da-app-01\Data\Tracker\uploads\33\test1.pdf it has to include the drive path.

Your file needs to reference something like String path = HttpContext.Current.Server.MapPath("~/" + FileVirtualPath); within your controllers action.

You also have options of HostingEnvironment.MapPath("~/" + FileVirtualPath) or Server.MapPath("~/" + FileVirtualPath)
