  2. {  
  3. List<EducationalVideoViewModel> lst = new List<EducationalVideoViewModel>();  
  4. try  
  5. {  
  6. var Video = _context.TblEducationalVideo.ToList();  
  7. if (Video != null)  
  8. {  
  9. foreach (var item in Video)  
  10. {  
  11. EducationalVideoViewModel lst_Data = new EducationalVideoViewModel();  
  12. lst_Data.Name = item.Name;  
  13. lst_Data.Video = item.VideoPath;  
  14. lst.Add(lst_Data);  
  15. }  
  16. }  
  17. else  
  18. {  
  19. ViewBag.message = "No Record !";  
  20. }  
  21. }  
  22. catch(Exception ex)  
  23. {  
  24. ViewBag.message = "Internal Server Error";  
  25. var message = ex.InnerException.Message;  
  26. throw;  
  27. }  
  28. return View(lst);
