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
{
/// <summary>
/// Word文档合并类
/// </summary>
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
);
}
