c# 将PPT转换成HTML

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 ----------------------------------Office文件转换成Html格式--------------------------------------------------------------------------------------------------------------------------------------------------------- using Microsoft.Office.Core;
