DropDownListFor unable to set on string (MVC)

Hello People,
I have this issue:
I want to put the marital status on drop down list, when I make the register of the new user, and chose married or unmarried, and click on the save button, on my db i see that it received the id (1, 2) instead of "married" or "unmarried".
This is what I see on my db:

On my Folder Account -> AccountViewModels.cs I put these codes:

public class RegisterViewModel
{
[Required]
[Display(Name = "Etat civil")]
[Range(1, 2, ErrorMessage = "Veuillez choisir")]
public string Civilite { get; set;
}
public class EtatCivil
{
public int Id { get; set; }
public string Libelle { get; set; }
}

and on Controllers -> AccountController.cs

//
// GET: /Account/Register
[AllowAnonymous]
public ActionResult Register()
{
var lstEtat = new List
{
new EtatCivil {Id = 0, Libelle = "vide"},
new EtatCivil {Id = 1, Libelle = "Célibataire"},
new EtatCivil {Id = 2, Libelle = "Marié"}
};
ViewBag.ListEtatCivil = new SelectList(lstEtat, "Id", "Libelle");
return View();
}

//
// POST: /Account/Register
[HttpPost]
[AllowAnonymous]
[ValidateAntiForgeryToken]
public async Task Register(RegisterViewModel model)
{
if (!ModelState.IsValid) return View(model);
var user = new ApplicationUser() { UserName = model.UserName };
var result = await UserManager.CreateAsync(user, model.Password);
if (result.Succeeded)
{
try {
// ajout du user dans la table client
using (var dal = new DALEF.WebShopEntities())
{
dal.Client.Add(
new DALEF.Client
{
CLI_Nom = model.Nom,
CLI_Prenom = model.Prenom,
CLI_Civilite = model.Civilite,
CLI_Email = model.Email,
CLI_Adresse = model.Adresse,
CLI_CodePostal = model.CodePostal,
CLI_Ville = model.Ville,
CLI_Telephone = model.Telephone,
CLI_AspUser_Id = user.Id
});
dal.SaveChanges();
}
}
catch(Exception) {
//await UserManager.DeleteAsync(user);
ModelState.AddModelError("", "Echec création client, veuillez réessayer");
return View(model);
}
// on affecte le rôle client
UserManager.AddToRole(user.Id, "client");
await SignInAsync(user, isPersistent: false);
return RedirectToAction("Index", "Home");
}
var lstEtat = new List
{
new EtatCivil {Id = 0, Libelle = "vide"},
new EtatCivil {Id = 1, Libelle = "Célibataire"},
new EtatCivil {Id = 2, Libelle = "Marié"}
};
ViewBag.ListEtatCivil = new SelectList(lstEtat, "Id", "Libelle");
AddErrors(result);
// If we got this far, something failed, redisplay form
return View(model);
}

On my Views --> Register.cshtml

class="form-group">
@Html.LabelFor(m => m.Civilite, new { @class = "col-md-2 control-label" })
class="col-md-10">
@Html.DropDownListFor(m => m.Civilite, (SelectList)ViewBag.ListEtatCivil)

What am I missing?

Actually what I have done is this:
//
        // POST: /Account/Register
        [HttpPost]
        [AllowAnonymous]
        [ValidateAntiForgeryToken]
        public async Task Register(RegisterViewModel model)
        {
            var lstEtat = new List
            {
                new EtatCivil {Id = 0, Libelle = "vide"},
                new EtatCivil {Id = 1, Libelle = "Célibataire"},
                new EtatCivil {Id = 2, Libelle = "Marié"}
            };
            ViewBag.ListEtatCivil = new SelectList(lstEtat, "Id", "Libelle");
            if (!ModelState.IsValid) return View(model);
            var user = new ApplicationUser() { UserName = model.UserName };
            var result = await UserManager.CreateAsync(user, model.Password);
            if (result.Succeeded)
            {
                try {
                    // ajout du user dans la table client
                    using (var dal = new DALEF.WebShopEntities())
                    {

                        dal.Client.Add(
                            new DALEF.Client
                            {
                                CLI_Nom = model.Nom,
                                CLI_Prenom = model.Prenom,
                                CLI_Civilite = lstEtat.Find(x=>x.Id == int.Parse(model.Civilite)).Libelle,
                                CLI_Email = model.Email,
                                CLI_Adresse = model.Adresse,
                                CLI_CodePostal = model.CodePostal,
                                CLI_Ville = model.Ville,
                                CLI_Telephone = model.Telephone,
                                CLI_AspUser_Id = user.Id
                            });
                        dal.SaveChanges();
                    }

                }
                catch(Exception) {
                    //await UserManager.DeleteAsync(user);
                    ModelState.AddModelError("", "Echec création client, veuillez réessayer");
                    return View(model);
                }
                // on affecte le rôle client
                UserManager.AddToRole(user.Id, "client");
                await SignInAsync(user, isPersistent: false);
                return RedirectToAction("Index", "Home");
            }



            AddErrors(result);

            // If we got this far, something failed, redisplay form
            return View(model);
        }

And it works, I can see on my db the status on string and not on int. :)

Hi,
I think you are doing good ,but you need to change some little bit of code,
But i think just use break point and check value from dropdown ,i think you are not getting value ,value is coming now ID ,
solution is use js fucntion and store dropdown selected value insdie hidden filed and get inside action.
