Adding a dictionary to a collection - just the values?

I am filling a combobox with dropdown values of type WagonType. The function I am calling returns a dictionary where the key is the WagonTypeID and the value is the WagonType.

RepositoryItemComboBox comboWagonTypes;
Dictionary<int, WagonType> GetAllWagonTypes()
{
  ...
}

If I use AddRange to fill the collection will it insert only the values or both the keys and the values?

comboWagonTypes.Items.AddRange(GetAllWagonTypes());

Or do I need to iterate through the dictionary and insert the values myself?

foreach (var wagonType in GetAllWagonTypes())
   comboWagonTypes.Items.Add(wagonType.Value)

Just use the Values property. Dictionary has Keys and Values as properties. Give it a try!

You need to use the Values property of the dictionary.

Just do

comboWagonTypes.Items.AddRange(GetAllWagonTypes().Values);
