如何使用OOXML和c＃将Power Point幻灯片复制到演示文稿中

本文介绍了如何使用OOXML和c＃将Power Point幻灯片复制到演示文稿中的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

在一个循环中我使用OOXML和C＃创建Power Point幻灯片。后我保存它们（一次一个），我复制滑入使用以下代码Final_presentation.pptx文件：

公共无效CopySlideIntoPresentation（串slide_to_copy，串presentation_to_save） { //生成随机数 Random random = new Random（）; int i = random.Next（10,100000）; $ //将幻灯片复制到final_presentation using（PresentationDocument newDocument = PresentationDocument.Open（presentation_to_save，true）） { PresentationDocument templateDocument = PresentationDocument.Open（slide_to_copy，FALSE）; UINT UNIQUEID = GetMaxIdFromChild（newDocument.PresentationPart.Presentation.SlideMasterIdList）; UINT maxId = GetMaxIdFromChild（newDocument.PresentationPart.Presentation.SlideIdList）; // SlidePart oldPart = GetSlidePartByTagName（templateDocument，" RID1"）; SlidePart oldPart = templateDocument.PresentationPart.SlideParts.First（）; &NBSP ; SlidePart NEWPART = newDocument.PresentationPart.AddPart< SlidePart>（oldPart，"的SourceID" + I）; SlideMasterPart newMasterPart = newDocument.PresentationPart.AddPart（newPart.SlideLayoutPart.SlideMasterPart）; SlideIdList idList = newDocument.PresentationPart.Presentation.SlideIdList; $   ; //创建新的幻灯片ID maxId ++; $ SlideId newId = new SlideId（）; $ newId.Id = maxId; newId.RelationshipId =" sourceId" + i; idList.Append（newId）; $   ; //创建新的主幻灯片ID uniqueId ++; $ SlideMasterId newMasterId = new SlideMasterId（）; $ newMasterId.Id = uniqueId; newMasterId.RelationshipId = newDocument.PresentationPart.GetIdOfPart（newMasterPart）; &NBSP ; newDocument.PresentationPart.Presentation.SlideMasterIdList.Append（newMasterId）; &NBSP ; //更改幻灯片布局ID FixSlideLayoutIds（newDocument.PresentationPart）; $ //newPart.Slide.Save（）; templateDocument.Close（）; $ newDocument.PresentationPart.Presentation.Save（）; newDocument.Close（）; //返回true; } }

即使将所有幻灯片复制到final_presentation.pptx文件中，打开时也会出现以下错误：

" Powerpoint在final_presntation.pptx中找到了不可读的内容。您想恢复此演示文稿的内容吗？如果您信任此演示文稿的来源，请单击是"

我单击"是"和"是"。然后我得到：

"使用Microsoft Office Powerpoint无法打开该文件。是否要在Microsoft Office Online网站上搜索可以打开该文件的转换器？ "

我点击"否"我可以看到新的幻灯片插入到这个final_presentation文件中。

有人可以帮我解决这个错误吗？

谢谢

Within a loop I create Power Point slides using OOXML and C#. After I save them (one at a time) , I copy that slide into a Final_presentation.pptx file using the following code:

public void CopySlideIntoPresentation(string slide_to_copy, string presentation_to_save) { //generate a random number Random random = new Random(); int i = random.Next(10, 100000); //Copy slide into final_presentation using (PresentationDocument newDocument = PresentationDocument.Open(presentation_to_save, true)) { PresentationDocument templateDocument = PresentationDocument.Open(slide_to_copy, false); uint uniqueId = GetMaxIdFromChild(newDocument.PresentationPart.Presentation.SlideMasterIdList); uint maxId = GetMaxIdFromChild(newDocument.PresentationPart.Presentation.SlideIdList); //SlidePart oldPart = GetSlidePartByTagName(templateDocument, "rId1"); SlidePart oldPart = templateDocument.PresentationPart.SlideParts.First(); SlidePart newPart = newDocument.PresentationPart.AddPart<SlidePart>(oldPart, "sourceId" + i); SlideMasterPart newMasterPart = newDocument.PresentationPart.AddPart(newPart.SlideLayoutPart.SlideMasterPart); SlideIdList idList = newDocument.PresentationPart.Presentation.SlideIdList; // create new slide ID maxId++; SlideId newId = new SlideId(); newId.Id = maxId; newId.RelationshipId = "sourceId" + i; idList.Append(newId); // Create new master slide ID uniqueId++; SlideMasterId newMasterId = new SlideMasterId(); newMasterId.Id = uniqueId; newMasterId.RelationshipId = newDocument.PresentationPart.GetIdOfPart(newMasterPart); newDocument.PresentationPart.Presentation.SlideMasterIdList.Append(newMasterId); // change slide layout ID FixSlideLayoutIds(newDocument.PresentationPart); //newPart.Slide.Save(); templateDocument.Close(); newDocument.PresentationPart.Presentation.Save(); newDocument.Close(); //return true; } }

Even though all the slides get copied into final_presentation.pptx file, I get the following error when open it:

"Powerpoint found unreadable content in final_presntation.pptx. Do you want to recover the contents of this presentation? If you trust the source of this presentation click Yes"

I click "yes" and then I get:

"The file cannot be open by using Microsoft Office Powerpoint. Do you want to search the Microsoft Office Online website for a converter that can open the file? "

I click "No" and I can see the new slide inserted into this final_presentation file.

Can someone help me to solve this error?

THANKS
