Cars.Add(new Car() { Name = "Peugeut", Series = new ObservableCollection<string>() { "106", "206", "306" } });
Cars.Add(new Car() { Name = "Ford", Series = new ObservableCollection<string>() { "406", "506", "606" } });
Cars.Add(new Car() { Name = "BMW", Series = new ObservableCollection<string>() { "706", "806", "906" } });
DataContext = this;
}
public ObservableCollection<Car> Cars { get; set; }
}
public class Car
{
public string Name { get; set; }
public ObservableCollection<string> Series { get; set; }
}
我希望这将有所帮助。
