Что я хочу сделать: **
Сохраните candidate.Description, candidate.Title, candidate.DateOfDescription, candidate.Saving в список внутри модели кандидата, после сохранения данных с помощью Foreach в представлении ( Я уже сделал ForEach ).
Candidate.Cs (модель):
public int Id { get; set; }
public string Name { get; set; }
public int Number { get; set; }
public string ProfileText { get; set; }
public Byte[] CV { get; set; }
public string CVNAME { get; set; }
public List<Profile> ProfileList { get; set; }
public String Description { get; set; }
public Boolean Saving { get; set; }
public string Title { get; set; }
public DateTime DateOfDescription { get; set; }
public List<Candidate> DescriptionList { get; set; }
public Candidate()
{
DescriptionList = new List<Candidate>();
}
Мой КандидатКонтроллер:
public IActionResult CandidateHistory(int Id)
{
using (var applicationcontext = new ApplicationContext())
{
var candidate = applicationcontext.Candidates.AsNoTracking().Include(q => q.DescriptionList).Single(q => q.Id == Id); //Recieving all the data from the Candidate With the ID = Id
if (candidate == null) //if Candidate isn't found return a error page
{
return NotFound();
}
return View(candidate);
}
}
[HttpPost, ActionName("CandidateHistory")]
[ValidateAntiForgeryToken]
public IActionResult CandidateHistoryPost([Bind("Description, Title, DateOfDescription, Saving")]Candidate candidate, int Id)
{
try
{
if (ModelState.IsValid)
{
using (var applicationContext = new ApplicationContext())
{
var candidates = applicationContext.Candidates.AsNoTracking().Include(q => q.DescriptionList).Single(q => q.Id == Id); //Getting all the DATA from the Candidate with the Id passed in the Get Method
candidates.DescriptionList.Add(new Candidate {
Description = candidate.Description,
Title = candidate.Title,
DateOfDescription = candidate.DateOfDescription,
Saving = candidate.Saving }); //Adds to the DescrptionList all the Description Data Needed
applicationContext.Candidates.Update(candidates);
applicationContext.SaveChanges();
return RedirectToAction("CandidateHistory");
}
}
}
catch (DbUpdateException ex )
{
//Log the error (uncomment ex variable name and write a log.
ModelState.AddModelError("", "Unable to save changes. " +"Try again, and if the problem persists " +"see your system administrator.");
}
return View();
}

Candidate candidate - это получение значения введенных данных в представлении (candidate.Description, candidate.Title, candidate.DateOfDescription, candidate.Saving), var candidates - получение данных из БД (Candidate.Id, Candidate.Name, Candidate.ProfileText, CandidateCv и т. Д. (Все, кроме описания / заголовка / сохранения / даты описания))
С этим кодом у меня проблема только:
Создает и добавляет в список все описания, но в конце также создает и пустой кандидат (не должен этого делать).
как видите, "пустые" кандидаты сохраняют Descriptin / History 
**
Candidate candidate получает это значение 
и candidates получает это:
