艾伟_转载：用C#编程合并多个WORD文档

今天因为客户需要，需要将多个WORD文档合并成为一个WORD文档。其中，对WORD文档的合并方式分两种形式：
一是复制合并;
一是插入合并,即将多个文档按照先后顺序合并到另一个文档中.

代码如下:

using System;using System.Collections.Generic;using System.Text;using Microsoft.Office.Interop.Word;using System.Reflection;using System.IO;using System.Diagnostics;namespace Eipsoft.Common{////// Word文档合并类///    public class WordDocumentMerger    {private ApplicationClass objApp = null;private Document objDocLast = null;private Document objDocBeforeLast = null;public WordDocumentMerger()        {            objApp = new ApplicationClass();        }#region 打开文件private void Open(string tempDoc)        {object objTempDoc = tempDoc;object objMissing = System.Reflection.Missing.Value;

objDocLast = objApp.Documents.Open(ref objTempDoc,    //FileName                 ref objMissing,   //ConfirmVersions                 ref objMissing,   //ReadOnly                 ref objMissing,   //AddToRecentFiles                 ref objMissing,   //PasswordDocument                 ref objMissing,   //PasswordTemplate                 ref objMissing,   //Revert                 ref objMissing,   //WritePasswordDocument                 ref objMissing,   //WritePasswordTemplate                 ref objMissing,   //Format                 ref objMissing,   //Enconding                 ref objMissing,   //Visible                 ref objMissing,   //OpenAndRepair                 ref objMissing,   //DocumentDirection                 ref objMissing,   //NoEncodingDialog                 ref objMissing    //XMLTransform                 );

objDocLast.Activate();        }#endregion

#region 保存文件到输出模板private void SaveAs(string outDoc)        {object objMissing = System.Reflection.Missing.Value;object objOutDoc = outDoc;            objDocLast.SaveAs(ref objOutDoc,      //FileName              ref objMissing,     //FileFormat              ref objMissing,     //LockComments              ref objMissing,     //PassWord                  ref objMissing,     //AddToRecentFiles              ref objMissing,     //WritePassword              ref objMissing,     //ReadOnlyRecommended              ref objMissing,     //EmbedTrueTypeFonts              ref objMissing,     //SaveNativePictureFormat              ref objMissing,     //SaveFormsData              ref objMissing,     //SaveAsAOCELetter,              ref objMissing,     //Encoding              ref objMissing,     //InsertLineBreaks              ref objMissing,     //AllowSubstitutions              ref objMissing,     //LineEnding              ref objMissing      //AddBiDiMarks              );        }#endregion
