{
var worldRepository = new WorldDataRepository();
Data = new ObservableCollection<DataItem>();
ItemsSource = new ObservableCollection<CountryItem>();
worldRepository.GetCountries().ContinueWith(list =>
{
Countries = list.Result;
var dataItems = new ObservableCollection<DataItem>();
foreach (var item in Countries)
{
var countryItem = new CountryItem
{
Name = item.Name,
Change = item.Chg1Y,
IsChangePositive = item.IsChangePositive
};
double val = 0.0;
double.TryParse(item.LifeExpectancy, out val);
countryItem.LifeExpectancy = val;
ItemsSource.Add(countryItem);
}
foreach (var region in worldRepository.CountriesByRegion)
{
var dataItem = new DataItem {Label = region.Key, Level = region.Value.Sum(x => x.Level.ToDouble())};
dataItems.Add(dataItem);
}
WorldPopulation = dataItems.Sum(l => l.Level * 1000).ToString("#,##0,,,.B", CultureInfo.InvariantCulture);
LifeExpectancy = ItemsSource.Average(x => x.LifeExpectancy).ToString("00.00", CultureInfo.InvariantCulture);
Data = dataItems;
});
