Csharp调用微软COM转换ppt为HTML

Csharp调用微软COM转换ppt为HTML

使用微软的office中的ppt软件只要使用另存为就可以把一个ppt保存为HTML网页文件。但如何通过程序调用完成转化呢？

以下使用office 2007为例，其他版本略有不同。

 1添加引用，对于不同的版本，有所不一样。当然前提自然是安装了对应的微软office软件。

2转换代码如下：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using PPT = Microsoft.Office.Interop.PowerPoint;
using Microsoft.Office.Core;
namespace CommonConvert
{public class PPTToHtml{/// <summary>/// 使用反射调用方法,返回生成的HTML文件路径/// </summary>/// <param name="pptFullFileName"></param>/// <returns></returns>public string PptToHtmlFile(object pptFullFileName){//在此处放置用户代码以初始化页面 PPT.Application ppt = new PPT.Application();Type wordType = ppt.GetType();PPT.Presentations docs = ppt.Presentations;//打开文件 Type docsType = docs.GetType();PPT.Presentation doc = (PPT.Presentation)docsType.InvokeMember("Open", System.Reflection.BindingFlags.InvokeMethod, null, docs, new Object[] { pptFullFileName, false,false,false });// PPT.Presentation doc = (PPT.Presentation)docsType.InvokeMember("Open", System.Reflection.BindingFlags.InvokeMethod, null, docs, new Object[] { pptFullFileName});//后三个参数不设置，会出现错误Presentations.Open : Invalid request.  The PowerPoint Frame window does not exist.Type docType = doc.GetType();string htmlFullFileName = pptFullFileName + ".html"; //HTML文件路径 object ofmt = PPT.PpSaveAsFileType.ppSaveAsHTML;//转换格式，另存为 docType.InvokeMember("SaveAs", System.Reflection.BindingFlags.InvokeMethod, null, doc, new object[] { htmlFullFileName, ofmt });docType.InvokeMember("Close", System.Reflection.BindingFlags.InvokeMethod, null, doc, null);//退出  wordType.InvokeMember("Quit", System.Reflection.BindingFlags.InvokeMethod, null, ppt, null);return htmlFullFileName;}/// <summary>/// 直接调用方法，不使用反射/// </summary>/// <param name="pptFullFileName"></param>/// <returns></returns>public string PptToHtmlFile2(string pptFullFileName){//在此处放置用户代码以初始化页面 PPT.Application ppt = new PPT.Application();          PPT.Presentations docs = ppt.Presentations;//打开文件 PPT.Presentation doc = docs.Open(pptFullFileName, MsoTriState.msoFalse, MsoTriState.msoFalse, MsoTriState.msoFalse);//  PPT.Presentation doc = docs.Open(pptFullFileName); //后三个参数不设置，会出现错误Presentations.Open : Invalid request.  The PowerPoint Frame window does not exist.string htmlFullFileName = pptFullFileName + ".html"; //HTML文件路径 //转换格式，另存为      doc.SaveAs(htmlFullFileName, PPT.PpSaveAsFileType.ppSaveAsHTML);doc.Close();//退出           ppt.Quit();return htmlFullFileName;}}
}
