示例1: DerivedCollectionsShouldRaiseListChangedEvents
public void DerivedCollectionsShouldRaiseListChangedEvents()
{
var input = new[] { "Foo", "Bar", "Baz", "Bamf" };
var fixture = new ReactiveList<TestFixture>(
input.Select(x => new TestFixture() { IsOnlyOneWord = x }));
IBindingList output = fixture.CreateDerivedBindingList(new Func<TestFixture, string>(x => x.IsOnlyOneWord));
var capturedEvents = new List<ListChangedEventArgs>();
output.ListChanged += (o, e) => capturedEvents.Add(e);
input.AssertAreEqual((IEnumerable<string>)output);
fixture.Add(new TestFixture() { IsOnlyOneWord = "Hello" });
Assert.Equal(capturedEvents.Last().ListChangedType,ListChangedType.ItemAdded);
Assert.Equal(5, output.Count);
Assert.Equal("Hello", output[4]);
fixture.RemoveAt(4);
Assert.Equal(capturedEvents.Last().ListChangedType, ListChangedType.ItemDeleted);
Assert.Equal(4, output.Count);
//replacing results in
//1 itemdeleted
//2 itemadded
fixture[1] = new TestFixture() { IsOnlyOneWord = "Goodbye" };
Assert.Equal(4, output.Count);
Assert.Equal("Goodbye", output[1]);
Assert.Equal(capturedEvents[capturedEvents.Count - 2].ListChangedType, ListChangedType.ItemDeleted);

fixture.Clear();
Assert.Equal(0, output.Count);
