Bind wpf listbox to ObservableCollection of tuples

Question

I have created ObservableCollection<Tuple<string,string>> servers; every tuple contains two fields Is it possible to bind this collection to listBox - so, that after binding there are only name strings in this listBox?

the Name String - is the first string from the tuple

private ObservableCollection<Tuple<string,string>> nameVals;

 public ObservableCollection<Tuple<string,string>> NameVals
        {
            get
            {
                if (nameVals == null)
                     nameVals= new ObservableCollection<Tuple<string, string>>(Helpers.getNamesAndValues("ololo"));
                return nameVals;
            }
        }

您可以将ListBox的ItemsSource绑定到ObservableCollection（！必须为属性），然后在ListBox上设置DisplayMemberPath="Item1" 。
