c#将PPT转换成HTML

作者:佚名      ASP.NET网站开发编辑:admin      更新时间:2022-07-23

这只是一个小程序,就是将PPT转换成html,方法很多,为了以后备用,在此记录一下,也和大家分享 源码如下: using System; using System.Collections.Generic; using System.Text; using System.IO; using PPT = Microsoft.Office.Interop.Powerpoint; using

 

这只是一个小程序,就是将ppt转换成html,方法很多,为了以后备用,在此记录一下,也和大家分享
  源码如下:
   

using System;
  using System.Collections.Generic;
  using System.Text;
  using System.IO;
  using PPT = Microsoft.Office.Interop.PowerPoint;
  using System.Reflection;

namespace WritePptDemo
  {
      class PRogram
      {
          static void Main(string[] args)
          {
              string   path;         //文件路径变量

              PPT.application pptApp;     //Excel应用程序变量
                PPT.Presentation pptDoc;     //Excel文档变量

              PPT.Presentation pptDoctmp;

           

            path   = @"C:\MyPPT.ppt";      //路径
              pptApp =   new PPT.ApplicationClass();   //初始化

            //如果已存在,则删除
              if   (File.Exists((string)path))
              {
                    File.Delete((string)path);
              }

            //由于使用的是COM库,因此有许多变量需要用Nothing代替
              Object   Nothing = Missing.Value;
              pptDoc =   pptApp.Presentations.Add(Microsoft.Office.Core.MsoTriState.msoFalse);
                pptDoc.Slides.Add(1,   Microsoft.Office.Interop.PowerPoint.PpSlideLayout.ppLayoutText);

              string text = "示例文本";

            foreach   (PPT.Slide slide in pptDoc.Slides)
              {
                    foreach (PPT.Shape shape in slide.Shapes)
                    {
                        shape.TextFrame.TextRange.InsertAfter(text);
                    }
              }


                //WdSaveFormat为Excel文档的保存格式
                PPT.PpSaveAsFileType format = PPT.PpSaveAsFileType.ppSaveAsDefault;

            //将excelDoc文档对象的内容保存为XLSX文档 
                pptDoc.SaveAs(path, format, Microsoft.Office.Core.MsoTriState.msoFalse);

            //关闭excelDoc文档对象 
                pptDoc.Close();

            //关闭excelApp组件对象 
                pptApp.Quit();

              Console.WriteLine(path + " 创建完毕!");

              Console.ReadLine();


              string   pathHtml = @"c:\MyPPT.html";

              PPT.Application pa = new PPT.ApplicationClass();

              pptDoctmp = pa.Presentations.Open(path,   Microsoft.Office.Core.MsoTriState.msoTrue,   Microsoft.Office.Core.MsoTriState.msoFalse,   Microsoft.Office.Core.MsoTriState.msoFalse);
                PPT.PpSaveAsFileType formatTmp = PPT.PpSaveAsFileType.ppSaveAsHTML;
                pptDoctmp.SaveAs(pathHtml, formatTmp,   Microsoft.Office.Core.MsoTriState.msoFalse);
                pptDoctmp.Close();
              pa.Quit();
                Console.WriteLine(pathHtml + " 创建完毕!");
          }
      }
  }
 
 
  以上程序是使用C# 先创建一个ppt 文件并向里面写入了文字,然后再把此ppt 转换成html  ,对于上面程序需要说明的其实就是
  引用dll的问题, 在项目中添加引用,在com 组件中选择 microsoft powerpoint 11.0 object   library ,而如果你的电脑没有安装 office 2003 是不会有这个的,而如果安装的是office 2007 则是microsoft powerpoint 12.0 object   library。而且即使你引用成功后,还是会编译不通过,是因为少安装了 office   PIA  ,在安装office 时,如果你是选择的典型安装是不会安装这个的,因为这个只针对开发人员才会用到。可以到网上下载一个 office PIA 安装下就ok了
