C#实现文档转换成PDF

网上有很多将doc、ppt、xls等类型的文档转换成pdf的方法,目前了解到的有两大类:

1.使用虚拟打印机将doc、ppt、xls等类型的文档

2.使用OFFICE COM组件

我采用了第二种方法实现,初步测试通过,还没有放到服务器上进行批量实时转换的测试。

下面开始介绍详细步骤:

1.安装OFFICE 2007.我安装的是OFFICE 2007 Professional Plus版。安装后提示要激活,开始没有激活也能使用,只是每次一打开office软件就提示要激活,实在忍受不了,就下了一个激活破解补丁。我用的是Office 2007 最新全系列激活验证破解补丁(适用于2007任何版本)绿色免费版激活的。

2.安装"另存为PDF或XPS加载项",可以从官网下载,其他地方也有一大把下载链接。我是从这个地址下载的

3.新建项目,添加如下引用:

Microsoft PowerPoint 12.0 Object Library

Microsoft Word 12.0 Object Library

Microsoft Excel 12.0 Object Library

这三个引用在“添加引用”对话框的COM选项卡里,只有安装了OFFICE 2007后才能看到,系统了安装的是OFFICE 2003的话,看到的是11.0的。

4.添加以上COM引用后,在项目的引用目录下,会看到自动添加了“Microsoft.Office.Interop.Word”、“Microsoft.Office.Interop.Excel”、“Microsoft.Office.Interop.PowerPoint”、“Microsoft.Office.Core”四个引用项,分别右击前三个,选属性,选择”嵌入互操作类型“值为false。如不做此项操作,编译项目时会出现”无法嵌入互操作类型“Microsoft.Office.Interop.Excel.ApplicationClass”。请改用适用的接口“的错误提示。

5.在代码中添加如下命名空间引用:

1 using Microsoft.Office.Core;
2 using Microsoft.Office.Interop.Excel;
3 using Microsoft.Office.Interop.PowerPoint;
4 using Word = Microsoft.Office.Interop.Word;
5 using Excel = Microsoft.Office.Interop.Excel;
6 using PowerPoint = Microsoft.Office.Interop.PowerPoint;

开始我以为不用第1-3行,结果发现没有这三行编译通不过。第4-6行的作用仅仅是为了在后面代码中简写命名空间。

6.添加如下三个转换函数:

7.调用相应函数进行转换:

Convert("C:\\1.doc", "C:\\1.pdf", wd);

开发工具是Visual Studio 2010,Windows XP SP3操作系统,OFFICE 2007.调试了doc,ppt,xls三种格式文件的转换,word测试了一个12页的文档,全部是中文文字。Excel测试了一个有3个sheet的文档(中英文和数字,某些行有背景色),转换后3个表格全部转到一个pdf文件中,无错误。转换速度很快,只是在转换PPT的时候出现了一个“正在发布...”的对话框,完成后对话框消失。不知道如何禁止出现提示框,优质稻的朋友看到贴后麻烦回复告知。

 

为方便使用,将文档转换的代码做成了一个dll,在项目中直接调用dll中的函数即可进行转换。欢迎点击下载
