示例1: GetContainers
public virtual void GetContainers()
{
ListBox control = new ListBox { ItemsSource = new[] { 1, 2, 3, 4, 5 } };
IEnumerable<DependencyObject> containers = null;
IEnumerable<ListBoxItem> items = null;
List<DependencyObject> allContainers = null;
List<ListBoxItem> allItems = null;
TestAsync(
control,
() => containers = control.GetContainers(),
() => items = control.GetContainers<ListBoxItem>(),
() => Assert.IsNotNull(containers, "containers should not be null!"),
() => allContainers = new List<DependencyObject>(containers),
() => Assert.AreEqual(5, allContainers.Count, "containers should have 5 items!"),
() => Assert.IsNotNull(items, "items should not be null!"),
() => allItems = new List<ListBoxItem>(items),
() => Assert.AreEqual(5, allItems.Count, "items should have 5 items!"),
() =>
{
for (int i = 0; i < allItems.Count; i++)
{
Assert.AreEqual(allItems[i], allContainers[i], "Container {0} does not match item {0}!", i);
}
},
() =>
{
for (int i = 0; i < allItems.Count; i++)
{
Assert.AreEqual(i + 1, control.ItemContainerGenerator.ItemFromContainer(allItems[i]), "Container {0} does not map to the correct item!", i);
}
});
