为了让PowerPoint文档更加精美，在制作文档的过程中，我们通常会给PowerPoint文档中的元素如形状、图片、表格等添加动画。本文将介绍如何使用.NET PowerPoint组件Spire.Presentation和C#编程的方式给PowerPoint中的形状添加动画，并修改和删除现有动画。
在开始前我们可以了解一下PowerPoint中的动画。在PowerPoint中，动画大致可分为以下四大类：
1. 进入
2. 强调
3. 退出
4. 动作路径
其中进入、强调和退出类型下有多种不同的预设动画效果，有些动画效果还可以添加子效果，例如“进入”分类下的“随机线条”动画效果，可以设置水平方向或垂直方向子效果（默认为水平方向）。下图展示了如何在PowerPoint中添加动画：
如何在Spire.Presentation中添加动画
Spire.Presentation支持约151种动画效果（可以在AnimationEffectType枚举中查看），这些动画效果及其所属分类和子效果，请参见文末附表。
在使用以下代码前，需要下载Spire.Presentation安装, 并从安装路径下引用Spire.Presentation.dll到工程中（或可从NuGet搜索Spire.Presentation并安装）。
添加动画
//加载文档
Presentation ppt = new Presentation();
ppt.LoadFromFile("Input.pptx");
//获取第一张幻灯片
ISlide slide = ppt.Slides[0];
RectangleF rect = new RectangleF(50, 200, 200, 200);
//添加形状到幻灯片
IShape cubeShape = slide.Shapes.AppendShape(ShapeType.Cube, rect);
//给形状添加动画效果
AnimationEffectCollection sequence = slide.Timeline.MainSequence;
AnimationEffect effect = sequence.AddEffect(cubeShape, AnimationEffectType.Bounce);
//保存文档
ppt.SaveToFile("Output.pptx", FileFormat.Pptx2013); 
通常我们添加的动画效果默认是“进入”效果，下面的代码将介绍如何添加“退出”动画效果：
//加载文档
Presentation ppt = new Presentation();
ppt.LoadFromFile("Input.pptx");
//获取第一张幻灯片
ISlide slide = ppt.Slides[0];
RectangleF rect = new RectangleF(50, 200, 200, 200);
//添加形状到幻灯片
IShape cubeShape = slide.Shapes.AppendShape(ShapeType.Cube, rect);
//给形状添加动画效果
AnimationEffectCollection sequence = slide.Timeline.MainSequence;
AnimationEffect effect = sequence.AddEffect(cubeShape, AnimationEffectType.RandomBars);
//将动画效果从默认的“进入”效果改为“退出”效果
effect.PresetClassType = TimeNodePresetClassType.Exit;
//给该动画添加子效果
effect.Subtype = AnimationEffectSubtype.Vertical;
//保存文档
ppt.SaveToFile("ExitAnimationEffect.pptx", FileFormat.Pptx2013); 
修改动画
对文档中的现有动画，我们可以对其进行修改。下面的代码将介绍如何修改现有动画的类型和持续时间。
修改动画类型
//加载文档
Presentation ppt = new Presentation();
ppt.LoadFromFile("Output.pptx");
//获取第一张幻灯片
ISlide slide = ppt.Slides[0];
//修改第一个动画的类型
AnimationEffectCollection sequence = slide.Timeline.MainSequence;
sequence[0].AnimationEffectType = AnimationEffectType.GrowAndTurn;
//保存文本
ppt.SaveToFile("EditAnimationType.pptx", FileFormat.Pptx2013);修改持续时间
//加载文档
Presentation ppt = new Presentation();
ppt.LoadFromFile("Output.pptx");
//获取第一张幻灯片
ISlide slide = ppt.Slides[0];
//修改第一个动画的持续时间
AnimationEffectCollection sequence = slide.Timeline.MainSequence;
sequence[0].Timing.Duration = 5;
//保存文档
ppt.SaveToFile("EditAnimationTime.pptx", FileFormat.Pptx2013);删除动画
//加载文档
Presentation ppt = new Presentation();
ppt.LoadFromFile("Output.pptx");
//获取第一张幻灯片
ISlide slide = ppt.Slides[0];
//删除第一个动画
AnimationEffectCollection sequence = slide.Timeline.MainSequence;
sequence.RemoveAt(0);
//保存文档
ppt.SaveToFile("RemoveAnimation.pptx", FileFormat.Pptx2013);附表（Spire.Presentation中动画效果及其所属分类和子效果）：
