Download ZIP file From path stored in Database MVC C#

Question

Need to download zip file content, path is stored in sqlserver, i am using FILERESULT Action method in controller. My Controller looks like this:

public FileResult Download(string id)
{
    string txtvalue = null; int cat = 0;

    string searchType = Session["type"].ToString();
    if (searchType == "name")
    {
        txtvalue = Session["item"].ToString();
    }
    else if (searchType == "cat")
    {
        cat = Convert.ToInt32(Session["item"]);
    }
    int fid =Convert.ToInt32(Session["Fid"]);
    var files = _urepo.GetprojectName(fid);
    string filename = (from f in files
                       select f.PRJ_LOCATION).SingleOrDefault();
    string contentType = "application/zip";

    return File(filename, contentType,"download"+filename);
}

But only file is downloading...contents are not downloading.. any help will be apprciated

Answer 1

Try something like this,first of all you need to check whether you are fetching file from Database or not? so condition will help you,another thing try to change "Content Type"

if (filename != null)
 {
      contentType = "application/force-download";
      return File(filename, contentType, Path.GetFileName(filename));
 }

Note : I have not posted full code,but the only place where chances mistake.

I Got It , Actually As CodeCaster Said, Contents were Missing While Archiving . Later I appended data With Ajax Call.

public FileResult Download()
        {
            int Id = Convert.ToInt32(TempData["FileID"]);

            var files = _urepo.GetprojectName(Id);
            string filename = (from f in files
                               select f.PRJ_LOCATION).SingleOrDefault();
            string contentType = "application/zip";
           byte[] fileBytes = System.IO.File.ReadAllBytes(filename);

            string file=filename.Substring(filename.LastIndexOf("\\")+1);
             return File(fileBytes, contentType, file);
        }

Thank You All.
