}示例2: FilteringPreservesCurrentItemIfItPassesTheFilterOtherwiseCurrentItemIsSetToTheFirstInTheFilteredView
public void FilteringPreservesCurrentItemIfItPassesTheFilterOtherwiseCurrentItemIsSetToTheFirstInTheFilteredView ()
{
CollectionView c = new CollectionView (new int [] { 1, 2, 3 });
c.Filter = FilteringPreservesCurrentItemIfItPassesTheFilterOtherwiseCurrentItemIsSetToTheFirstInTheFilteredViewFilter1;
Assert.AreEqual (c.CurrentItem, 1, "1");
c.Filter = FilteringPreservesCurrentItemIfItPassesTheFilterOtherwiseCurrentItemIsSetToTheFirstInTheFilteredViewFilter2;
// Why?
Assert.AreEqual (c.CurrentItem, 1, "2");
c.Refresh ();
Assert.AreEqual (c.CurrentItem, 1, "3");
Assert.IsFalse (c.PassesFilter (c.CurrentItem), "4");
Assert.AreEqual (c.CurrentPosition, 0, "5");
