    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:
      

     
    复制代码 代码如下:
    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
