获取IEnumerable的元素

Question

I am getting a list of objects like this:

IEnumerable personeller = (IEnumerable)sicil_model.OlayForm_Personel();

I am looping inside it like this

foreach (var personel in personeller)
{
 //can't do anything...
}

I am looping inside personeller and I can see all elements like this

personeller[0] | { Id = 5, Kimlik = "Koray Durudoğan", EMail = "koray@outlook.com", DepartmanAdi = "Yazilim", PozisyonAdi = "Yazilim Geliştirme" }

personeller[1] | { Id = 6, Kimlik = "Hasan Pınar", EMail = "hasan@dincerelektronik.com.tr", DepartmanAdi = "Yazilim", PozisyonAdi = "Yazilim Geliştirme" }
    .
    .
    .

And goes like this.. The thing is, I can't access elements of objects. For example, how can I get Id of personeller[0] or Kimlik of personeller[1] ?

I made a class like this

public class Personel_Form 
{
    public int Id { get; set; }
    public string Kimlik { get; set; }
    public string EMail { get; set; }
    public string DepartmanAdi { get; set; }
    public string PozisyonAdi { get; set; }
}

but I couldn't manage to convert 'personel' to this class, inside my foreach loop.

Lastly, Here is the method which turns the list:

public object OlayForm_Personel() 
    {
        return (from p in Entity.GetEntity().Sicil
                           select new 
                           {
                            Id = p.Id,
                            Kimlik = p.Isim + " " + p.Soyad,
                            EMail = p.EMail,
                            DepartmanAdi = p.Departman.DepartmanAdi,
                            PozisyonAdi = p.Pozisyon1.PozisyonAdi
                           }).ToList();
    }

Answer 1

From your sentence of I am looping inside personeller and I can see all elements like this and the given sample data I deduce that the collection returned by the function stores items of the Personel_Form type.

Two options:

1. You are casting it into the non genetic IEnumerable that holds the items as object s. you can cast it to the correct type:

    IEnumerable personeller = (IEnumerable)sicil_model.OlayForm_Personel(); foreach (var personel in personeller) { var personalForm = (Personel_Form)personel; // personalForm.Kimlik } 

2. But a better approach is : instead of using the non generic IEnumerable use the generic IEnumerable<T> :

    IEnumerable<Personel_Form> personeller = sicil_model.OlayForm_Personel(); 

---

As for your latest errors (from comments) it is because your function returns an anonymous type and not the Personel_Form type. Instead if instantiating an anonymous object instantiate a Personel_Form :

public IEnumerable<Personel_Form> OlayForm_Personel() 
{
    return (from p in Entity.GetEntity().Sicil
           select new Personel_Form
           {
            Id = p.Id,
            Kimlik = p.Isim + " " + p.Soyad,
            EMail = p.EMail,
            DepartmanAdi = p.Departman.DepartmanAdi,
            PozisyonAdi = p.Pozisyon1.PozisyonAdi
           }).ToList();
}

Answer 2

If its possible, you could change your method from

public object OlayForm_Personel() 
    {
        return (from p in Entity.GetEntity().Sicil
                           select new 
                           {
                            Id = p.Id,
                            Kimlik = p.Isim + " " + p.Soyad,
                            EMail = p.EMail,
                            DepartmanAdi = p.Departman.DepartmanAdi,
                            PozisyonAdi = p.Pozisyon1.PozisyonAdi
                           }).ToList();
    }

to

public IEnumerable<Personel_Form> OlayForm_Personel() 
    {
        return (from p in Entity.GetEntity().Sicil
                           select new Personel_Form
                           {
                            Id = p.Id,
                            Kimlik = p.Isim + " " + p.Soyad,
                            EMail = p.EMail,
                            DepartmanAdi = p.Departman.DepartmanAdi,
                            PozisyonAdi = p.Pozisyon1.PozisyonAdi
                           }).ToList();
    }

then you could change your consuming code to this

var personeller = sicil_model.OlayForm_Personel();

foreach (var personel in personeller)
{
    // personel.Kimlik
}
