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：
