adding enum values to a simple combobox

i have a really simple question to ask about C# and WPF. My Question will follow after this attempt of mine:

private void Window_Loaded(object sender, RoutedEventArgs e)
        {
            foreach (var item in Races)
            {
                cbRace.Items.Add(item);
            }
        }
    }

    enum Races
    {
        Human=1,
        Dwarf,
        Elf,
        Orc,
        Goblin,
        Vampire,
        Centaur
    }

Ok so, my question is how will I add the values(e.g. Human,dwarf,elf....) into the combo box: cbRace? sorry I'm new to C# so i would rally appreciate it if someone can help me out :), thanks in advance.

You should be able to do something like this:

cbRace.ItemsSource = Enum.GetValues(typeof(Races));

Checkout this answer for more information on setting and retrieving the enum values.

Given something like

public class ComboBoxItem
{
    public ComboBoxItem(int id, string text)
    {
      Id = id;
      Text = text;
    }
    
    public int Id { get; set; }
    public string Text { get; set; }
    
    public override string ToString() => Text;
}

you could use

public static IEnumerable<ComboBoxItem> GetAsComboBoxItems<TEnum>()
{
  foreach (var enumValue in Enum.GetValues(typeof(TEnum)))
  {
    yield return new ComboBoxItem((int)enumValue, enumValue.ToString());
  }
}

and then

cbRace.DataSource = GetAsComboBoxItems<Races>().ToList();

cmbUserType.Items.AddRange(core.Global.ToObjectArray(Enum.GetValues(typeof(STATUS))));
public enum STATUS { INACTIVE, ACTIVE }

Shortest Way to add Enum Values to Combobox in C# 

class User{

public enum TYPE { EMPLOYEE, DOCTOR, ADMIN };

}

// Add this class to your form load event of Form Cunstructor

cmbUserType.Items.AddRange(Enum.GetNames(typeof(User.TYPE)));

This isn't a preferred solution as Clemens has already given you that but if you wanted to add in the XAML directly you could also do 

<ComboBox>
    <urCode:Races>Human</urCode:Races>
    <urCode:Races>Dwarf</urCode:Races>
    <urCode:Races>Elf</urCode:Races>
</ComboBox>

you could also implment an IValueConverter that when bound to a Type, returns the Enum.GetValues

This would perhaps be the easiest way to set the ComboBox items:

private void Window_Loaded(object sender, RoutedEventArgs e)
{
    cbRace.ItemsSource = Enum.GetValues(typeof(Races));
    cbRace.SelectedIndex = 0;
}

It is not necessary to loop over the enum values, just set the ItemsSource property.

use this

cbRace.Datasource = Enum.GetValues(typeof(Races));

to databind your enum to the combobox and then use selectedValue and selectedText properties of your combobox to retreive names and values;
