ASP.NET 將Word轉換成PDF

1、基於Office的解決方案

　　

　　 1.獲取指定文件夾下的全部word文件

static void Main(string[] args)
        {

            try
            {
                Console.WriteLine("------------開始---------------");
                string path = @"XXXXXXXXXXXXXXXXXX";//word所在的文件夾
                string SaveFile = @"XXXXXXXXXXXXXXXXXX";//保存路徑
                DirectoryInfo di = new DirectoryInfo(path);

                Console.Write("請輸入指定名稱(不輸入獲取全部文件):");
                string filename = Console.ReadLine();

                //找到該目錄下的文件 
                FileInfo[] FileList;
                if (!string.IsNullOrEmpty(filename))
                {
                    FileList = di.GetFiles(filename);
                }
                else
                {
                    FileList = di.GetFiles();
                }
                int Success = 0;
                int Fail = 0;
                foreach (FileInfo item in FileList)
                {
                    string Filescr = SaveFile + item.Name;
                    bool bFlagPdf = Common.FileWordToPdf.ConvertToPdf(item.FullName, Filescr);
                    if (bFlagPdf == true)
                    {
                        Success++;
                        Console.WriteLine(item.Name + "   -----  轉換成功");
                    }
                    else
                    {
                        Fail++;
                        Console.WriteLine(item.Name + "   -----  轉換失敗");
                    }
                }
                Console.WriteLine("------------結束,結果以下:---------------");
                Console.WriteLine("需生PDF共:" + FileList.Length + "份");
                Console.WriteLine("成功PDF共:" + Success + "份協議");
                Console.WriteLine("失敗PDF共:" + Fail + "份協議");
                Console.ReadKey();
            }

            catch (Exception ex)
            {
                Console.WriteLine(ex.ToString());
            }
        }

 　　2.建立一個Helper類

using Microsoft.Office.Interop.Word;
using System.IO;
public class FileWordToPdf_Helper
    {
      
        /// <summary>
        /// 直接使用Word轉PDF
        /// </summary>
        /// <param name="mWordSrc">Word路徑</param>
        /// <param name="SavsFile">保存路徑</param>
        /// <returns></returns>
        public static bool ConvertToPdf(string mWordSrc,string SavsFile)
        {
            try
            {
                #region Com component
                Microsoft.Office.Interop.Word.Application appWord = null;
                object oMissing = System.Reflection.Missing.Value;
                if (appWord == null)
                {
                    appWord = new Microsoft.Office.Interop.Word.Application();
                }
                Microsoft.Office.Interop.Word.Document doc = appWord.Documents.Open(mWordSrc);
                doc.Activate();
                string mPDFSrc = Path.ChangeExtension(SavsFile, "pdf");
                doc.ExportAsFixedFormat(mPDFSrc, WdExportFormat.wdExportFormatPDF);
                object saveChanges = WdSaveOptions.wdDoNotSaveChanges;
                ((_Document)doc).Close(ref saveChanges, ref oMissing, ref oMissing);
                doc = null;
                ((_Application)appWord).Quit(ref oMissing, ref oMissing, ref oMissing);
                appWord = null;
                GC.Collect();
                GC.WaitForPendingFinalizers();
                #endregion
                return true;
            }
            catch (Exception ex)
            {
                return false;
                throw (ex);
            }
        }

    }
