【源码】C#开发之Word批量转PDF

转自：http://www.cnblogs.com/hans_gis/archive/2013/05/25/3098558.html

微软Office Word本身已经提供了另存为PDF文档功能，对于少量文档，手工使用该方式进行Word转换为PDF尚可，一旦需要处理大量的文档，可能就显得有些捉襟见肘了。不过对于已经安装有Office环境，借助一些简单的代码即可实现批量Word转PDF了。

源码奉上：

?

using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Diagnostics; using System.IO; using System.Text; using System.Threading; using Microsoft.Office.Interop.Word;   namespace Word2Pdf {     class Program     {         public static Microsoft.Office.Interop.Word.Document wordDocument { get; set; }           static void Main(string[] args)         {             string strFolder_f = null;             string strFolder_t = null;             string strFlag = null;             System.Console.WriteLine("请输入Word文档所在目录");             strFolder_f = System.Console.ReadLine();             if (strFolder_f.Substring(strFolder_f.Length - 1, 1) != "\\")             {                 strFolder_f += "\\";             }             strFolder_t = strFolder_f + @"pdf\";             System.Console.WriteLine("\n创建PDF文档，请确认！");             System.Console.Write("y(yes) or n(no) ?  ");             strFlag = System.Console.ReadLine();             if (strFlag == "y")             {                 System.Console.WriteLine("\n开始创建PDF文档...");                 CheckFolder(strFolder_t);                 string strPdfFile = null;                 DirectoryInfo TheFolder = new DirectoryInfo(strFolder_f);                   Microsoft.Office.Interop.Word.Application appWord = new Microsoft.Office.Interop.Word.Application();                 object paramMissing = Type.Missing;                   foreach (FileInfo NextFile in TheFolder.GetFiles())                 {                     strPdfFile = Path.ChangeExtension(strFolder_t + NextFile.Name, ".pdf");                     wordDocument = appWord.Documents.Open(NextFile.FullName);                     if (wordDocument != null)                     {                         wordDocument.ExportAsFixedFormat(strPdfFile, WdExportFormat.wdExportFormatPDF);                         wordDocument.Close(ref paramMissing, ref paramMissing, ref paramMissing);                         wordDocument = null;                     }                     System.Console.Write(".. ");                 }                   if (appWord != null)                 {                     appWord.Quit(ref paramMissing, ref paramMissing, ref paramMissing);                     appWord = null;                 }             }               //KillProcessByName("WINWORD");             GC.Collect();             GC.WaitForPendingFinalizers();               System.Console.Write("\n处理完毕，输入任意键退出");             System.Console.ReadKey();         }           static void CheckFolder(string strFolderPath)         {             if (Directory.Exists(strFolderPath))             {                 Directory.Delete(strFolderPath, true);                 Directory.CreateDirectory(strFolderPath);             }             else             {                 Directory.CreateDirectory(strFolderPath);             }         }           static void KillProcessByName(string name)         {             Process[] ps = Process.GetProcessesByName(name);             foreach (Process p in ps)             {                 if (p.ProcessName == name)                     p.Kill();             }         }     } }

需要注意的两个问题：①及时关闭代码中所打开的文档，见49行，否则会产生临时文件；②及时关闭“WINWORD”线程，否则所处理的Word文档会一直处于被该线程占用的情况。
