C#实现将PPT转换成HTML的方法
本文是一个C#的小程序，主要实现将ppt转换成html的功能,方法很多，此处与大家分享一下，希望能对大家的项目开发起到一定的借鉴作用。
主要功能代码如下：
usingSystem;
usingSystem.Collections.Generic;
usingSystem.Text;
usingSystem.IO;
usingPPT=Microsoft.Office.Interop.PowerPoint;
usingSystem.Reflection;
namespaceWritePptDemo
{
classProgram
{
staticvoidMain(string[]args)
{
stringpath;//文件路径变量
PPT.ApplicationpptApp;//Excel应用程序变量
PPT.PresentationpptDoc;//Excel文档变量
PPT.PresentationpptDoctmp;
path=@"C:\MyPPT.ppt";//路径
pptApp=newPPT.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
ObjectNothing=Missing.Value;
pptDoc=pptApp.Presentations.Add(Microsoft.Office.Core.MsoTriState.msoFalse);
pptDoc.Slides.Add(1,Microsoft.Office.Interop.PowerPoint.PpSlideLayout.ppLayoutText);
stringtext="示例文本";
foreach(PPT.SlideslideinpptDoc.Slides)
{
foreach(PPT.Shapeshapeinslide.Shapes)
{
shape.TextFrame.TextRange.InsertAfter(text);
}
}
//WdSaveFormat为Excel文档的保存格式
PPT.PpSaveAsFileTypeformat=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();
stringpathHtml=@"c:\MyPPT.html";
PPT.Applicationpa=newPPT.ApplicationClass();
pptDoctmp=pa.Presentations.Open(path,Microsoft.Office.Core.MsoTriState.msoTrue,Microsoft.Office.Core.MsoTriState.msoFalse,Microsoft.Office.Core.MsoTriState.msoFalse);
PPT.PpSaveAsFileTypeformatTmp=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microsoftpowerpoint11.0object library，而如果你的电脑没有安装office2003是不会有这个的，而如果安装的是office2007则是microsoftpowerpoint12.0object 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officePIA安装下就ok了
Office文件转换成Html格式功能代码如下：

usingMicrosoft.Office.Interop.PowerPoint;
usingSystem;
usingSystem.Collections.Generic;
usingSystem.Linq;
usingSystem.Text;
usingSystem.Web;
usingSystem.IO;
usingSystem.Text.RegularExpressions;
usingNd.Webs;
usingAspose.Cells;
usingAspose.Words;
usingND.CommonHelper;
usingMicrosoft.Office.Interop.PowerPoint;
usingMicrosoft.Office.Core;
namespaceApi.Note.Base
{
#regionOffice文件转换成Html格式
classOfficeHtmlBo
{
#regionInsertHeadHtml
///<summary>
///InsertHeadHtml

///<paramname="WordFilePath">InsertHeadHtml</param>
privatestringInsertHeadHtml(stringstrHtml,stringrealPath)
{
intindex=strHtml.IndexOf("<body");
strHtml=strHtml.Insert(index,"<divstyle='height:60px;font-size:14px;margin:0px0px12px0px;padding:14px4px12px12px;line-height:24px;height:1%;'>以下是该文档的HTML预览效果。<br/><span>由于是网页提取显示word中的内容，有可能部分显示与源文档中有差异，如想查看更准确的信息，</span>您可以点击 <astyle='color:6699FF;text-decoration:underline;'href='/Lib/UdControls/Download.aspx?action=Download&appFormCode="+HttpContext.Current.Request.QueryString["appFormCode"].ToString()+"&path="+HttpContext.Current.Request.QueryString["path"].ToString()+"&encrypt="+HttpContext.Current.Request.QueryString["encrypt"].ToString()+"'><b>下载原始附件</b></a></div>");
Regexreg=newRegex(@"(?<start><img[^>]+?src="")(?<src>[^""]+?)(?<end>""[^>]+?>)");
strHtml=reg.Replace(strHtml,delegate(Matchm)
{
returnstring.Format("{0}{1}{2}{3}",
m.Groups["start"].Value,
realPath,
m.Groups["src"].Value,
m.Groups["end"].Value
);
});
returnstrHtml;
