本文实例讲述了C#实现合并多个word文档的方法，是非常具有实用价值的技巧。分享给大家供大家参考。
具体实现方法如下：
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using Microsoft.Office.Interop.Word;
using System.Reflection;
using System.IO;
using System.Diagnostics;
namespace driverexam.WordReport
{
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
