示例1: DoubleAnimationKeyFrameRepeatTest

animation = new DoubleAnimationUsingKeyFrames();
animation.KeyFrames.Add(new LinearDoubleKeyFrame { KeyTime = KeyTime.FromTimeSpan(TimeSpan.FromSeconds(0)), Value = 0 });
animation.KeyFrames.Add(new LinearDoubleKeyFrame { KeyTime = KeyTime.FromTimeSpan(TimeSpan.FromSeconds(1)), Value = 1 });
animation.Duration = new Duration(TimeSpan.FromSeconds(2));
animation.RepeatBehavior = RepeatBehavior.Forever;
TestRootClock rootClock = new TestRootClock();
AnimationTimelineClock clock = (AnimationTimelineClock)animation.CreateClock();
clock.Begin(rootClock);
rootClock.Tick(TimeSpan.FromSeconds(0.1));
Assert.AreEqual(0.1, (double)animation.GetCurrentValue(0.0, 0.0, clock));
rootClock.Tick(TimeSpan.FromSeconds(0.9));
Assert.AreEqual(0.9, (double)animation.GetCurrentValue(0.0, 0.0, clock));
rootClock.Tick(TimeSpan.FromSeconds(1));
Assert.AreEqual(1, (double)animation.GetCurrentValue(0.0, 0.0, clock));
rootClock.Tick(TimeSpan.FromSeconds(1.9));
Assert.AreEqual(1, (double)animation.GetCurrentValue(0.0, 0.0, clock));
rootClock.Tick(TimeSpan.FromSeconds(2.1));
