为了将Office文档转换为PDF文件，在网上找了些工具类，但转换效果不理想，采用office自带的功能能比较好的实现转换。
首先需要安装 SaveAsPDFandXPS.exe 插件
在工程中添加com引用，如下图
代码如下：
1: using System;
2: using System.Collections.Generic;
3: using System.Text;
4:
5: using Microsoft.Office.Core;
6: using Word = Microsoft.Office.Interop.Word;
7: using Excel = Microsoft.Office.Interop.Excel;
8: using PowerPoint = Microsoft.Office.Interop.PowerPoint;
9:
10: using System.IO;
11: using System.Runtime.InteropServices;
