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;

  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
