前言

開發(fā).NET項目常用的和office相關(guān)的庫有開源組件Apose.Slides和Spire.Presentation,以及微軟自帶的Microsoft.office.interop.PowerPoint組件。

微軟自帶的Microsoft.office.interop.PowerPoint組件雖然免費，但是需要在服務(wù)器端安裝PowerPoint，且需要配置DCOM組件權(quán)限，并且原生方法有限，導入附件、圖片等功能收到限制，經(jīng)過權(quán)衡，放棄使用微軟自帶的組件。

Apose.Slides和Spire.Presentation這兩個都是商業(yè)軟件，試用版和免費版的只有能生成前10頁，還帶有水印。Free Spire.Presentation可以沒有能超過十頁，否則需要購買商業(yè)付費版。

但是網(wǎng)上存在Apose.Slides的破解版本，可以完美解鎖大部分常用功能，最終采用Apose.Slides.net 17.9作為最終的開發(fā)組件，經(jīng)過測試滿足此次開發(fā)需求。

開發(fā)環(huán)境

Visual Studio 2019

Microsoft Visual Studio是微軟公司的開發(fā)工具包系列產(chǎn)品。VS是一個基本完整的開發(fā)工具集，它包括了整個軟件生命周期中所需要的大部分工具，如UML工具、代碼管控工具、集成開發(fā)環(huán)境（IDE）等等。所寫的目標代碼適用于微軟支持的所有平臺。Visual Studio包含基于組件的開發(fā)工具（如Visual C#、Visual J#、Visual Basic和Visual C++），以及許多用于簡化基于小組的解決方案的設(shè)計、開發(fā)和部署的其他技術(shù)。

這里我們主要使用的是Visual Studio的Visual C#開發(fā)工具。

Microsoft開發(fā)組件

Apose.Slides.dll
開發(fā)過程中，需要引用上述類庫，用于創(chuàng)建、操作、保存PPT等操作。

Apose.Slides.dll 主要功能函數(shù)

創(chuàng)建PPT

// Instantiate a Presentation object that represents a presentation fileusing (Presentation presentation = new Presentation()){
    // Get the first slide    ISlide slide = presentation.Slides[0];
    // Add an autoshape of type line    slide.Shapes.AddAutoShape(ShapeType.Line, 50, 150, 300, 0);
    presentation.Save("NewPresentation_out.pptx", SaveFormat.Pptx);}

保存PPT

// Instantiate a Presentation object that represents a PPT file
Presentation presentation= new Presentation();
//...do some work here...// Save your presentation to a filepresentation.Save("Saved_out.pptx", 
Aspose.Slides.Export.SaveFormat.Pptx);

增加PPT

// Instantiate Presentation class that represents a presentation file
using (Presentation pres = new Presentation("CloneWithinSamePresentationToEnd.pptx")){
// Clone the desired slide to the end of the collection of slides in the same presentation    
ISlideCollection slds = pres.Slides;
slds.AddClone(pres.Slides[0]);
    // Write the modified presentation to disk    
    pres.Save("Aspose_CloneWithinSamePresentationToEnd_out.pptx", SaveFormat.Pptx);
}

刪除PPT

// Instantiate a Presentation object that represents a presentation file
using (Presentation pres = new Presentation("RemoveSlideUsingReference.pptx")){
// Accessing a slide using its index in the slides collection    
    ISlide slide = pres.Slides[0];
// Removing a slide using its reference    
    pres.Slides.Remove(slide);
//Writing the presentation file    
    pres.Save("modified_out.pptx", Aspose.Slides.Export.SaveFormat.Pptx);
    }

修改PPT文本

using(Presentation pres = new Presentation("text.pptx")){
   foreach (ISlide slide in pres.Slides)
   {
       foreach (IShape shape in slide.Shapes)
       {
           if (shape is IAutoShape autoShape) //Checks if shape supports text frame (IAutoShape).            {
              foreach (IParagraph paragraph in autoShape.TextFrame.Paragraphs) //Iterates through paragraphs in text frame               {
                   foreach (IPortion portion in paragraph.Portions) //Iterates through each portion in paragraph                   {
                       portion.Text = portion.Text.Replace("years", "months"); //Changes text                       portion.PortionFormat.FontBold = NullableBool.True; //Changes formatting                   }
               }
           }
       }
   }
   //Saves the modified presentation   
   pres.Save("text-changed.pptx", SaveFormat.Pptx);}

增加圖片導入

using (Presentation pres = new Presentation()){
    ISlide slide = pres.Slides[0];
    IPPImage image = pres.Images.AddImage(File.ReadAllBytes("image.png"));
    slide.Shapes.AddPictureFrame(ShapeType.Rectangle, 10, 10, 100, 100, image);
    pres.Save("pres.pptx", SaveFormat.Pptx);}

增加視頻導入

// Instantiate Presentation class that represents the PPTX
using (Presentation pres = new Presentation()){
// Get the first slide    
ISlide sld = pres.Slides[0];
// Embedd vide inside presentation    
IVideo vid = pres.Videos.AddVideo(new FileStream("Wildlife.mp4", FileMode.Open));
// Add Video Frame    
IVideoFrame vf = sld.Shapes.AddVideoFrame(50, 150, 300, 350, vid);
// Set video to Video Frame    
vf.EmbeddedVideo = vid;
// Set Play Mode and Volume of the Video    
vf.PlayMode = VideoPlayModePreset.Auto;
    vf.Volume = AudioVolumeMode.Loud;
// Write the PPTX file to disk    
pres.Save("VideoFrame_out.pptx", SaveFormat.Pptx);}

增肌OLE文件導入

using (Presentation pres = new Presentation()){
  ISlide slide = pres.Slides[0];
  
  byte[] htmlBytes = File.ReadAllBytes("embedOle.html");
  IOleEmbeddedDataInfo dataInfoHtml = new OleEmbeddedDataInfo(htmlBytes, "html");
  IOleObjectFrame oleFrameHtml = slide.Shapes.AddOleObjectFrame(150, 120, 50, 50, dataInfoHtml);
  oleFrameHtml.IsObjectIcon = true;
  byte[] zipBytes = File.ReadAllBytes("embedOle.zip");
  IOleEmbeddedDataInfo dataInfoZip = new OleEmbeddedDataInfo(zipBytes, "zip");
  IOleObjectFrame oleFrameZip = slide.Shapes.AddOleObjectFrame(150, 220, 50, 50, dataInfoZip);
  oleFrameZip.IsObjectIcon = true;
  pres.Save("embeddedOle.pptx", SaveFormat.Pptx);}

增加文本框

// Instantiates PresentationExusing (Presentation pres = new Presentation()){
// Gets the first slide in the presentation    
ISlide sld = pres.Slides[0];
// Adds an AutoShape with type set as Rectangle    
IAutoShape ashp = sld.Shapes.AddAutoShape(ShapeType.Rectangle, 150, 75, 150, 50);
// Adds TextFrame to the Rectangle    
ashp.AddTextFrame(" ");
// Accesses the text frame    
ITextFrame txtFrame = ashp.TextFrame;
// Creates the Paragraph object for text frame    
IParagraph para = txtFrame.Paragraphs[0];
// Creates a Portion object for the paragraph    
IPortion portion = para.Portions[0];
// Sets the text    
portion.Text = "Aspose TextBox";
// Saves the presentation to disk   
 pres.Save("TextBox_out.pptx", Aspose.Slides.Export.SaveFormat.Pptx);}
