C#中怎么合并多个WORD文档，很多新手对此不是很清楚，为了帮助大家解决这个难题，下面小编将为大家详细讲解，有这方面需求的人可以来学习下，希望你能有所收获。
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 ); } #endregion #region 循环合并多个文件（复制合并重复的文件） /// <summary> /// 循环合并多个文件（复制合并重复的文件） /// </summary> /// <param name="tempDoc">模板文件</param> /// <param name="arrCopies">需要合并的文件</param> /// <param name="outDoc">合并后的输出文件</param> public void CopyMerge(string tempDoc, string[] arrCopies, string outDoc) { object objMissing = Missing.Value; object objFalse = false; object objTarget = WdMergeTarget.wdMergeTargetSelected; object objUseFormatFrom = WdUseFormattingFrom.wdFormattingFromSelected; try { //打开模板文件 Open(tempDoc); foreach (string strCopy in arrCopies) { objDocLast.Merge( strCopy, //FileName ref objTarget, //MergeTarget ref objMissing, //DetectFormatChanges ref objUseFormatFrom, //UseFormattingFrom ref objMissing //AddToRecentFiles ); objDocBeforeLast = objDocLast; objDocLast = objApp.ActiveDocument; if (objDocBeforeLast != null) { objDocBeforeLast.Close( ref objFalse, //SaveChanges ref objMissing, //OriginalFormat ref objMissing //RouteDocument ); } } //保存到输出文件 SaveAs(outDoc); foreach (Document objDocument in objApp.Documents) { objDocument.Close( ref objFalse, //SaveChanges ref objMissing, //OriginalFormat ref objMissing //RouteDocument ); } } finally { objApp.Quit( ref objMissing, //SaveChanges ref objMissing, //OriginalFormat ref objMissing //RoutDocument ); objApp = null; } } /// <summary> /// 循环合并多个文件（复制合并重复的文件） /// </summary> /// <param name="tempDoc">模板文件</param> /// <param name="arrCopies">需要合并的文件</param> /// <param name="outDoc">合并后的输出文件</param> public void CopyMerge(string tempDoc, string strCopyFolder, string outDoc) { string[] arrFiles = Directory.GetFiles(strCopyFolder); CopyMerge(tempDoc, arrFiles, outDoc); } #endregion #region 循环合并多个文件（插入合并文件） /// <summary> /// 循环合并多个文件（插入合并文件） /// </summary> /// <param name="tempDoc">模板文件</param> /// <param name="arrCopies">需要合并的文件</param> /// <param name="outDoc">合并后的输出文件</param> public void InsertMerge(string tempDoc, string[] arrCopies, string outDoc) { object objMissing = Missing.Value; object objFalse = false; object confirmConversion = false; object link = false; object attachment = false; try { //打开模板文件 Open(tempDoc); foreach (string strCopy in arrCopies) { objApp.Selection.InsertFile( strCopy, ref objMissing, ref confirmConversion, ref link, ref attachment ); } //保存到输出文件 SaveAs(outDoc); foreach (Document objDocument in objApp.Documents) { objDocument.Close( ref objFalse, //SaveChanges ref objMissing, //OriginalFormat ref objMissing //RouteDocument ); } } finally { objApp.Quit( ref objMissing, //SaveChanges ref objMissing, //OriginalFormat ref objMissing //RoutDocument ); objApp = null; } } /// <summary> /// 循环合并多个文件（插入合并文件） /// </summary> /// <param name="tempDoc">模板文件</param> /// <param name="arrCopies">需要合并的文件</param> /// <param name="outDoc">合并后的输出文件</param> public void InsertMerge(string tempDoc, string strCopyFolder, string outDoc) { string[] arrFiles = Directory.GetFiles(strCopyFolder); InsertMerge(tempDoc, arrFiles, outDoc); } #endregion } }看完上述内容是否对您有帮助呢？如果还想对相关知识有进一步的了解或阅读更多相关文章，请关注亿速云行业资讯频道，感谢您对亿速云的支持。
