程序生成的PowerPoint演示文稿打破了PowerPoint 2013
本文关键字：PowerPoint 文稿打 2013 程序生成 | 更新日期: 2023-09-27 18:26:33
我正在尝试从不同的来源生成演示文稿。基本上，我有大约200张PowerPoint演示文稿中的幻灯片。为了实现这一点，我使用了OpenXml Sdk。程序流程如下：
- 打开模板演示
- 打开新演示文稿
- 将第二个演示文稿中的幻灯片合并到模板演示文稿中
最后，我将把新的演示文稿保存到磁盘上。尝试使用PowerPoint 2013打开它会中断，并显示以下信息：问题签名：

然而，用PowerPoint 2010打开它效果很好。它没有问题。
这是代码：
private static void MergePresentation(string generatedPresentation, string presentationToBeMerged)
{
try
{
int id = 0;
// Open the destination presentation.
using (PresentationDocument generatedPresentationDeck = PresentationDocument.Open(generatedPresentation, true))
{
PresentationPart generatedPresentationPart = generatedPresentationDeck.PresentationPart;
// If the merged presentation does not have a SlideIdList
// element yet, add it.
if (generatedPresentationPart.Presentation.SlideIdList == null)
{
generatedPresentationPart.Presentation.SlideIdList = new SlideIdList();
}
// Open the source presentation. This will throw an exception if
// the source presentation does not exist.
using (PresentationDocument mySourceDeck = PresentationDocument.Open(presentationToBeMerged, false))
{
PresentationPart sourcePresPart = mySourceDeck.PresentationPart;
// Get unique ids for the slide master and slide lists
// for use later.
_uniqueId = GetMaxSlideMasterId(generatedPresentationPart.Presentation.SlideMasterIdList);
uint maxSlideId = GetMaxSlideId(generatedPresentationPart.Presentation.SlideIdList);
// Copy each slide in the source presentation, in order, to
// the destination presentation.
foreach (SlideId slideId in sourcePresPart.Presentation.SlideIdList)
{
SlidePart sp;
SlidePart destSp;
SlideMasterPart destMasterPart;
string relId;
SlideMasterId newSlideMasterId;
SlideId newSlideId;
// Create a unique relationship id.
id++;
sp = (SlidePart)sourcePresPart.GetPartById(slideId.RelationshipId);
//sp.Slide.Transition.Remove();
relId = Path.GetFileNameWithoutExtension(presentationToBeMerged).Replace(" ", "_") + id;
// Add the slide part to the destination presentation.
destSp = generatedPresentationPart.AddPart<SlidePart>(sp, relId);
// The slide master part was added. Make sure the
// relationship between the main presentation part and
// the slide master part is in place.
destMasterPart = destSp.SlideLayoutPart.SlideMasterPart;
generatedPresentationPart.AddPart(destMasterPart);
// Add the slide master id to the slide master id list.
_uniqueId++;
newSlideMasterId = new SlideMasterId();
newSlideMasterId.RelationshipId = generatedPresentationPart.GetIdOfPart(destMasterPart);
newSlideMasterId.Id = _uniqueId;
generatedPresentationPart.Presentation.SlideMasterIdList.Append(newSlideMasterId);
// Add the slide id to the slide id list.
maxSlideId++;
newSlideId = new SlideId();
newSlideId.RelationshipId = relId;
newSlideId.Id = maxSlideId;
generatedPresentationPart.Presentation.SlideIdList.Append(newSlideId);
}
// Make sure that all slide layout ids are unique.
FixSlideLayoutIds(generatedPresentationPart);
}
// Save the changes to the destination deck.
generatedPresentationPart.Presentation.Save();
}
}
catch (Exception ex)
{
throw ex;
}
}
/// <summary>
/// Find the maximum value of ID of all slide masters

/// <returns>
private static uint GetMaxSlideMasterId(SlideMasterIdList slideMasterIdList)
{
// Slide master identifiers have a minimum value of greater than
// or equal to 2147483648.
uint max = 2147483648;
if (slideMasterIdList != null)
// Get the maximum id value from the current set of children.
foreach (SlideMasterId child in
slideMasterIdList.Elements<SlideMasterId>())
{
uint id = child.Id;
if (id > max)
max = id;
}
return max;
}
/// <summary>
/// Find the maximum ID of all slides
/// </summary>
/// <param name="slideIdList" />
/// <returns>
private static uint GetMaxSlideId(SlideIdList slideIdList)
{
// Slide identifiers have a minimum value of greater than or
// equal to 256 and a maximum value of less than 2147483648.
uint max = 256;
if (slideIdList != null)
// Get the maximum id value from the current set of children.
foreach (SlideId child in slideIdList.Elements<SlideId>())
{
uint id = child.Id;
if (id > max)
max = id;
}
return max;
}
/// <summary>
/// Fix the IDs of all slide layouts by making sure that all the slide layout IDs in the
/// destination slide are unique.
/// </summary>
/// <param name="presPart" />
private static void FixSlideLayoutIds(PresentationPart presPart)
{
// Make sure that all slide layouts have unique ids.
foreach (SlideMasterPart slideMasterPart in presPart.SlideMasterParts)
{
foreach (SlideLayoutId slideLayoutId in slideMasterPart.SlideMaster.SlideLayoutIdList)
{
_uniqueId++;
slideLayoutId.Id = (uint)_uniqueId;
}
slideMasterPart.SlideMaster.Save();
}
}
我调用Merge函数的方式是：
string templateFilePath = @"C:'Users'mm'Desktop'testing pp'Presentation1.pptx";
string newFilePath = @"C:'Users'mm'Desktop'testing pp'Generated Presentation-105.pptx";
MergePresentation(templateFilePath, newFilePath);
有什么想法吗？
感谢
我已经找到了解决方案。张贴在这里，以防其他人遇到这个问题。
我已经在生成的演示文稿上使用了OpenXml Sdk Validator，发现了以下错误：元素具有意外的子元素"http://schemas.openxmlformats.org/presentationml/2006/main:notesMasterIdLst'
这让我注意到了幻灯片中的注释。删除它们解决了问题，一切都很好。
删除注释的代码（即使在PP中打开演示文稿时没有看到任何注释）：
public static void RemoveNotesFromDoc(string docPath)
{
try
{
using (PresentationDocument pDoc =
PresentationDocument.Open(docPath, true))
{
foreach (var slide in pDoc.PresentationPart.SlideParts)
{
NotesSlidePart notes = slide.NotesSlidePart;
if (notes != null)
{
slide.DeletePart(slide.GetIdOfPart(slide.NotesSlidePart));
}
}
}
}
}
