Need help, Not able to download the file

I have tried to download my file from the directory location but unable to download, and it does not give any error. Is this folder permission issue or something code is missing.

my complete directory path = C:\Users\abc\source\repos\SkylandApplication\WebApp\Upload\Documents\5\FranchiseData\Location\1\70054b29-20f1-438e-9c78-521a34107c9d.jpg

public ActionResult DownloadFranchiseLeftsideImg(CompanyLocationViewModel model)

{

try

{

CompanyLocationViewModel obj = Session["Location"] as CompanyLocationViewModel;

obj.LeftsideImg = model.LeftsideImg;

obj.RightsideImg = null;

obj.InsideImg = null;

obj.OutsideImg = null;

var LeftSideImg = repo_companylayoutlocation.LocationDownloads(obj);

string UploadedPath = System.Configuration.ConfigurationManager.AppSettings["ImagePath"];

string folderName = "FranchiseData/Location/" + obj.LocationId;

String absolutePath = System.Web.Hosting.HostingEnvironment.MapPath(UploadedPath + "\\" + obj.FranchiseId + "\\" + folderName);

string completePath = System.IO.Path.Combine(absolutePath, LeftSideImg);

byte[] fileBytes = System.IO.File.ReadAllBytes(completePath);

return File(fileBytes, System.Net.Mime.MediaTypeNames.Application.Octet, "LeftSideImg");

//var bytes = System.IO.File.ReadAllBytes(completePath);

//return File(completePath, MimeMapping.GetMimeMapping(completePath), LeftSideImg);

//return File(completePath, "application/force -download", LeftSideImg);

}

catch (Exception ex)

{

throw;

}

Madhav Sharma,

Good morning. You have to specify Content-Disposition and Content-Type. Could you please refer to the below code?

URL: I have checked in the code into my GitHub Repository. https://github.com/vishipayyallore/speaker_series/tree/master/C%23/DownloadFiles

public HttpResponseMessage Get(string fileName)
{
var response = Request.CreateResponse(HttpStatusCode.OK);
string filePath = HttpContext.Current.Server.MapPath("~/Downloads/") + fileName;
if (!File.Exists(filePath))
{
response.StatusCode = HttpStatusCode.NotFound;
response.ReasonPhrase = string.Format("File not found: {0} .", fileName);
throw new HttpResponseException(response);
}
byte[] bytes = File.ReadAllBytes(filePath);
response.Content = new ByteArrayContent(bytes);
response.Content.Headers.ContentLength = bytes.LongLength;
response.Content.Headers.ContentDisposition = new ContentDispositionHeaderValue("attachment")
{
FileName = fileName
};
response.Content.Headers.ContentType = new MediaTypeHeaderValue(MimeMapping.GetMimeMapping(fileName));
return response;
}
