Question

I have just started with my project using MVC and Razor. Now I am encountering a problem when it comes to binding data coming from the database to a dropdownlist. Please refer on my codes below:

Specialization Model:

public class SpecializationModel
{
    [Display(Name = "SpecializationID")]
    public string SpecializationID { get; set; }

    [Display(Name = "SpecializationDescription")]
    public string SpecializationDescription { get; set; }

    public IEnumerable<SelectListItem> Items { get; set; }
    public int SelectedSpecializationID { get; set; }
}

Controller:

public ActionResult Physicians()
{
    SpecializationManager spec = new SpecializationManager();
    List<Specialization> SpecializationList = spec.GetAllSpecialization();

    var obj = new SpecializationModel();

    obj.Items = new[]
    {
        foreach(var x in SpecializationList)
        {
            new SelectListItem { Value = x.SpecializationID.ToString(), Text = x.SpecializationDescription };
        }
    };

    return View(obj);
}

I have this manager which contains my LINQ query to extract the data from the database.
I encounter problems on the controller. Wherein the error points on the foreach syntax saying Invalid expression term foreach

Can anyone please point me to the right direction? Thanks a lot!

EDIT:

I have this code now without errors on the foreach part (thanks to the post below which I combined with what I have above). However, I can’t seem to make the last line work. It produces an error about implicit cast:

var items = new List<SelectListItem>();
foreach (var x in SpecializationList)
{
    items.Add(new SelectListItem { Value = x.SpecializationID.ToString(), Text = x.SpecializationDescription });
}

obj.Items = items.ToList();

Please do help me. Thanks 🙂

yopu can’t put a foreach in a constructor, try:

var items = new List<SelectListItem >();
foreach(var x in SpecializationList)
{
           items.add(new SelectListItem { Value = x.SpecializationID.ToString(), Text = x.SpecializationDescription });
}

obj.Items = items;
