asp.net实现将ppt文档转换成pdf的方法

本文实例讲述了asp.net实现将ppt文档转换成pdf的方法。。具体实现方法如下：

一、添加引用
using Microsoft.Office.Core;
using Microsoft.Office.Interop.PowerPoint;

二、转换方法

///<summary>       
/// 把PowerPoint文件转换成PDF格式文件      
///</summary>       
///<param name="sourcePath">源文件路径</param>    
///<param name="targetPath">目标文件路径</param>
///<returns>成功返回true,失败返回false</returns>
public static bool PPTConvertToPDF(string sourcePath, string targetPath)
{
        bool result;
        PpSaveAsFileType ppSaveAsFileType = PpSaveAsFileType.ppSaveAsPDF;//转换成pdf
        object missing = Type.Missing;
        Microsoft.Office.Interop.PowerPoint.ApplicationClass application = null;
        Presentation persentation = null;
        try
        {
            application = new Microsoft.Office.Interop.PowerPoint.ApplicationClass();
            persentation = application.Presentations.Open(sourcePath, MsoTriState.msoTrue, MsoTriState.msoFalse, MsoTriState.msoFalse);
            if (persentation!=null)
            {
                persentation.SaveAs(targetPath, ppSaveAsFileType, MsoTriState.msoTrue);
            }
            result = true;
        }
        catch
        {
            result = false;
        }
        finally
        {
            if (persentation != null)
            {
                persentation.Close();
                persentation = null;
