erp|转换如何使用.NET将PowerPoint转为HTML文件
我们当然要使用Com组件了，所以要先安装powerpoint2000,在VS.NET里面添加一个refrence,找到microsoft PowerPoint object library 9.0，添加进来。
然后写如下代码，很简单，我就不必解释了：）
using System;
using Office;
using PowerPoint;

namespace CourseServer.Course
{
    /// <summary>

    /// Version:1.0

    /// Description:转换PowerPoint的PPT文件为HTML文件
    /// </summary>
    public class ConvertPowerPoint
    {
        /// <summary>
        /// 建立对PowerPoint.Application的Com组件的引用
        /// </summary>
        private PowerPoint.Application ppt;
        /// <summary>

        /// </summary>
        private PowerPoint.Presentation pptFile;
        private string _HtmlFileName;
        /// <summary>
        /// 只写属性，设置另存的HTML文件的文件路径
        /// </summary>
        public string HtmlFileName
        {
            set
            {
                _HtmlFileName=value;
            }
        }

        /// <summary>

        public ConvertPowerPoint()
        {
            //
            // TODO: Add constructor logic here
            //
            
            ppt=new PowerPoint.Application();
        }
        /// <summary>
        /// 转换过程
        /// </summary>
        /// <param name="pptFileName">欲转换的PowerPoint文件名称</param>
        
        public void Convert(string pptFileName)
        {
            
            pptFile=ppt.Presentations.Open(pptFileName,Office.MsoTriState.msoTrue,Office.MsoTriState.msoCTrue,Office.MsoTriState.msoFalse);
            pptFile.SaveAs(_HtmlFileName,PowerPoint.PpSaveAsFileType.ppSaveAsHTML,Office.MsoTriState.msoCTrue);
            pptFile.Close();
                

        }
    }
