本文是一個C#的小法式，重要完成將ppt轉換成html的功效,辦法許多，此處與年夜家分享一下，願望能對年夜家的項目開辟起到必定的自創感化。
重要功效代碼以下：
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; //文件途徑變量
PPT.Application pptApp; //Excel運用法式變量
PPT.Presentation pptDoc; //Excel文檔變量
PPT.Presentation pptDoctmp;
path = @"C:\MyPPT.ppt"; //途徑
pptApp = new PPT.ApplicationClass(); //初始化
//假如已存在，則刪除
if (File.Exists((string)path))
{
File.Delete((string)path);
}
//因為應用的是COM庫，是以有很多變量須要用Nothing取代
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為Excel文檔的保留格局
PPT.PpSaveAsFileType format = PPT.PpSaveAsFileType.ppSaveAsDefault;
//將excelDoc文檔對象的內容保留為XLSX文檔
pptDoc.SaveAs(path, format, Microsoft.Office.Core.MsoTriState.msoFalse);
//封閉excelDoc文檔對象
pptDoc.Close();
//封閉excelApp組件對象
pptApp.Quit();
Console.WriteLine(path + " 創立終了！");
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 + " 創立終了！");
}
}
}
以上法式是應用C# 先創立一個ppt 文件並向外面寫入了文字，然後再把此ppt 轉換成html ,關於下面法式須要解釋的其實就是
援用dll的成績， 在項目中添加援用，在com 組件當選擇 microsoft powerpoint 11.0 object library ，而假如你的電腦沒有裝置 office 2003 是不會有這個的，而假如裝置的是office 2007 則是microsoft powerpoint 12.0 object library。並且即便你援用勝利後，照樣會編譯欠亨過，是由於少裝置了 office PIA ,在裝置office 時，假如你是選擇的典范裝置是不會裝置這個的，由於這個只針對開辟人員才會用到。可以到網高低載一個 office PIA 裝置下就ok了
