如何使用C＃应用程序打开Powerpoint PPTX文件？ [英] How can I open Powerpoint PPTX File with C# application?

问题描述

 使用 Microsoft.Office.Core; 
 使用 PowerPoint = Microsoft.Office.Interop.PowerPoint; 
 
 PowerPoint.Application oPPT; 
 PowerPoint.Presentations objPPTSHOW; 
 PowerPoint.Presentation objSHOW; 
 oPPT =  new  PowerPoint.ApplicationClass（）; 
 oPPT.Visible = Microsoft.Office.Core.MsoTriState.msoCTrue; 
 objPPTSHOW = oPPT.Presentations; 
 objSHOW = objPPTSHOW.Open（txtFILELOC.Text，MsoTriState.msoFalse，MsoTriState.msoCTrue，MsoTriState.msoCTrue）; 

我使用这个编码来打开PPT文件，但它不起作用。我正在使用C＃2005并选择了MicroSoft PowerPoint 12.0对象库。

错误显示COMException未处理。错误代码是-2147467259。有人可以帮我吗？

解决方案

 Microsoft.Office.Interop.PowerPoint.Application ppApp =  new  Microsoft.Office.Interop.PowerPoint.Application（）; 
 ppApp.Visible = MsoTriState.msoTrue; 
演示文稿ppPresens = ppApp.Presentations;演示文稿objPres = ppPresens.Open（e.FullPath，MsoTriState.msoFalse，MsoTriState.msoTrue，MsoTriState.msoTrue）; 
幻灯片objSlides = objPres.Slides; 
 Microsoft.Office.Interop.PowerPoint.SlideShowWindows objSSWs; Microsoft.Office.Interop.PowerPoint.SlideShowSettings objSSS; 
  //  运行幻灯片放映 
 objSSS = objPres.SlideShowSettings; 
 objSSS.Run（）; 
 objSSWs = ppApp.SlideShowWindows; 
  while （objSSWs.Count >  =  1 ）
 System.Threading.Thread.Sleep（ 100 ）; 
  //  关闭演示文稿而不保存更改并退出PowerPoint  
 objPres.Close （）; 
 ppApp.Quit（）; 

当它（Presentations.Open）打开大文件（> = 1G ppt文件）时，它加载非常慢慢地，以及如何处理它？<​​/ blockquote>

你是否想要这样做：



System.Diagnostics。 Process.Start（pptfilename.pptx）

using PowerPoint = Microsoft.Office.Interop.PowerPoint;

         PowerPoint.Application oPPT;
         PowerPoint.Presentations objPPTSHOW;
         PowerPoint.Presentation objSHOW;
         oPPT = new PowerPoint.ApplicationClass();
         oPPT.Visible = Microsoft.Office.Core.MsoTriState.msoCTrue;
         objPPTSHOW = oPPT.Presentations;
         objSHOW = objPPTSHOW.Open(txtFILELOC.Text, MsoTriState.msoFalse, MsoTriState.msoCTrue, MsoTriState.msoCTrue);

I use this coding for opening PPT File but it doesn't work. I'm using C# 2005 and selected MicroSoft PowerPoint 12.0 Object library.
error show COMException was unhandled. Error code is -2147467259. Anyone can help me please?

解决方案

Microsoft.Office.Interop.PowerPoint.Application ppApp = new Microsoft.Office.Interop.PowerPoint.Application();
ppApp.Visible = MsoTriState.msoTrue;
Presentations ppPresens = ppApp.Presentations;							Presentation objPres = ppPresens.Open(e.FullPath, MsoTriState.msoFalse, MsoTriState.msoTrue, MsoTriState.msoTrue);
Slides objSlides = objPres.Slides;
								Microsoft.Office.Interop.PowerPoint.SlideShowWindows objSSWs;							Microsoft.Office.Interop.PowerPoint.SlideShowSettings objSSS;
//Run the Slide show
objSSS = objPres.SlideShowSettings;
objSSS.Run();
objSSWs = ppApp.SlideShowWindows;
while(objSSWs.Count >= 1) 
System.Threading.Thread.Sleep(100);
//Close the presentation without saving changes and quit PowerPoint
objPres.Close();
ppApp.Quit();

When it（Presentations.Open） opens large files(>= 1G ppt file), it loads very slowly, and how to deal with it ?

Are you trying to do this:

System.Diagnostics.Process.Start("pptfilename.pptx")
