已知在OpenXml有以下几种超链接
| 功能 | 说明 |
|---|---|
| 跳转页面 | 跳转某一页：ppaction://hlinksldjump 跳转第一页：ppaction://hlinkshowjump?jump=firstslide 跳转最后一页：ppaction://hlinkshowjump?jump=lastslide 跳转下一页：ppaction://hlinkshowjump?jump=nextslide 跳转上一页：ppaction://hlinkshowjump?jump=previousslide |
| 跳转文件 | 跳转打开本地文件：ppaction://hlinkfile 跳转打开Office支持的主流文档类文件（office系文档、pdf、txt...）：ppaction://hlinkpres?slideindex=1&slidetitle= |
| 跳转网页 |
例子
我们先准备好这样一份pptx文件，如图：
我们分别为四个形状插入超链接，代码如下：
internal class Program { static void Main(string[] args) { var mainExecuteDirectory = Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location); var pptFilePath = Path.Combine(mainExecuteDirectory!, "YourPresentation.pptx"); // 打开一个PPTX文档 using PresentationDocument presentationDocument = PresentationDocument.Open(pptFilePath, true); var slideIdList = presentationDocument.PresentationPart!.Presentation.SlideIdList; if (slideIdList is null || !slideIdList.Any()) { return; } var firstSlideId =(SlideId) slideIdList.First(); // 获取页面内容 var firstSlidePart = (SlidePart) presentationDocument.PresentationPart.GetPartById(firstSlideId.RelationshipId!.Value!); //设置跳转到第三页 var targetSlideId = (SlideId) slideIdList.ChildElements[2]; var targetSlidePart = (SlidePart) presentationDocument.PresentationPart.GetPartById(targetSlideId.RelationshipId!.Value!); var relationshipId = firstSlidePart.CreateRelationshipToPart(targetSlidePart); var shapeElements = firstSlidePart.Slide.CommonSlideData!.ShapeTree!.Elements<Shape>().ToList(); //第一个形状设置跳转第三页 shapeElements[0]!.NonVisualShapeProperties!.NonVisualDrawingProperties!.HyperlinkOnClick = new HyperlinkOnClick() { Action = PptAction.SlideJump, Id = relationshipId }; //第二个形状设置跳转下一页 var shapeElement = shapeElements[1]; shapeElement.NonVisualShapeProperties!.NonVisualDrawingProperties!.HyperlinkOnClick = new HyperlinkOnClick() { Action = PptAction.JumpNextSlide, }; var filePath = Path.Combine(mainExecuteDirectory!, "两只老虎-原声.mp3"); var fileHyperlinkRelationship = firstSlidePart.AddHyperlinkRelationship(new Uri(filePath, UriKind.Absolute), true); //第三个形状设置打开文件 shapeElements[2]!.NonVisualShapeProperties!.NonVisualDrawingProperties!.HyperlinkOnClick = new HyperlinkOnClick() { Action = PptAction.OpenFile, Id = fileHyperlinkRelationship.Id }; //第四个形状设置打开网页链接 var httpHyperlinkRelationship = firstSlidePart.AddHyperlinkRelationship(new Uri($"http://www.baidu.com", UriKind.Absolute), true); shapeElements[3]!.NonVisualShapeProperties!.NonVisualDrawingProperties!.HyperlinkOnClick = new HyperlinkOnClick() { Id = httpHyperlinkRelationship.Id }; // 保存并关闭文档 presentationDocument.Save(); } } public static class PptAction { /// <summary> /// 跳转页面 /// </summary> public const string SlideJump = "ppaction://hlinksldjump"; /// <summary> /// 跳转下一页 /// </summary> public const string JumpNextSlide = "ppaction://hlinkshowjump?jump=nextslide"; /// <summary> /// 打开文件 /// </summary> public const string OpenFile = "ppaction://hlinkfile"; } 效果如下：
