return View();
}

return RedirectToAction("CustHome", "Customer");
}


[HttpPost]
public ActionResult Creating(FileloadView doc)
{
try
{
_db.Insert(doc);

return RedirectToAction("Uploaded");
}
catch (Exception e)
{

return View();
}
}

DataContext db = new DataContext();

public ActionResult Download()
{
return View(_db.GetAll());
}

public FileContentResult FileDownload(int? id)
{
byte[] fileData;
string fileName;

var x = new FileloadBusiness();
var fileRecord = db.FileLoads.Find(id);


fileData = (byte[])fileRecord.File.ToArray();
fileName = fileRecord.FileName;


return File(fileData, "text", fileName);
