示例1: ObservableCollectionTest
public void ObservableCollectionTest()
{
var originalCollection = new ObservableCollection<MyModel>() { new MyModel() };
var synchronizingCollection = new SynchronizingCollection<MyDataModel, MyModel>(originalCollection, m => new MyDataModel(m));
Assert.IsTrue(originalCollection.SequenceEqual(synchronizingCollection.Select(dm => dm.Model)));
// Check add operation with collection changed event.
bool handlerCalled = false;
NotifyCollectionChangedEventHandler handler = (sender, e) =>
{
handlerCalled = true;
Assert.AreEqual(synchronizingCollection, sender);
Assert.AreEqual(NotifyCollectionChangedAction.Add, e.Action);
Assert.AreEqual(1, e.NewStartingIndex);
Assert.AreEqual(originalCollection.Last(), e.NewItems.Cast<MyDataModel>().Single().Model);
};
synchronizingCollection.CollectionChanged += handler;
originalCollection.Add(new MyModel());
Assert.IsTrue(handlerCalled);
// After dispose the collection does not synchronize anymore
handlerCalled = false;
synchronizingCollection.Dispose();
originalCollection.Add(new MyModel());
Assert.IsFalse(handlerCalled);
synchronizingCollection.CollectionChanged -= handler;
}示例2: SetOriginalItemsSourceShouldGetDataFromPrevious
public void SetOriginalItemsSourceShouldGetDataFromPrevious()
{
var model = new GridModel { Name = "test" };
var listItems = new List<GridModel> { model };
var viewModel = GetViewModel<GridViewModel<GridModel>>();
viewModel.UpdateItemsSource(listItems);
var newItemsSource = new ObservableCollection<GridModel>();
viewModel.SetOriginalItemsSource(newItemsSource);
newItemsSource.SequenceEqual(listItems).ShouldBeTrue();
}
