C#实现合并多个word文档的方法

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, //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
