浅析C#合并多个WORD文档的具体实现方法

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 SystemCollectionsGeneric;

using SystemText;

using MicrosoftOfficeInteropWord;

using SystemReflection;

using SystemIO;

using SystemDiagnostics;

namespace EipsoftCommon

{

/// <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 = SystemReflectionMissingValue;

objDocLast = objAppDocumentsOpen(

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

);

objDocLastActivate();

}

#endregion

#region 保存文件到输出模板

private void SaveAs(string outDoc)

{

object objMissing = SystemReflectionMissingValue;

object objOutDoc = outDoc;

objDocLastSaveAs(

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
