asp.net将ppt文档转换成pdf

一、添加引用

 

using Microsoft.Office.Core;
using Microsoft.Office.Interop.PowerPoint;

 

二、转换方法

 

C# 代码   复制

    ///<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;
            }
            if (application != null)
            {
                application.Quit();
                application = null;
            }
        }
        return result;
    }

 

三、调用

 

OfficeToPdf.PPTToPDF("d:\\12345。pptx", "d:\\12345。pdf");
