首先引入Microsoft.Office.Interop.Word組件，該組件在安裝完office后在COM中出現(xiàn)。

代碼如下

using System;using System.Collections.Generic;using System.Diagnostics;using System.Linq;using System.Text;namespace TextReplace{ public class WordOperate : IDisposable {  private Microsoft.Office.Interop.Word._Application _app;  private Microsoft.Office.Interop.Word._Document _doc;  object _nullobj = System.Reflection.Missing.Value;  /// <summary>  /// 關(guān)閉Word進(jìn)程  /// </summary>  public void KillWinword()  {   var p = Process.GetProcessesByName("WINWORD");   if (p.Any()) p[0].Kill();  }  /// <summary>  /// 打開word文檔  /// </summary>  /// <param name="filePath"></param>  public void Open(string filePath)  {   _app = new Microsoft.Office.Interop.Word.ApplicationClass();   object file = filePath;   _doc = _app.Documents.Open(     ref file, ref _nullobj, ref _nullobj,     ref _nullobj, ref _nullobj, ref _nullobj,     ref _nullobj, ref _nullobj, ref _nullobj,     ref _nullobj, ref _nullobj, ref _nullobj,     ref _nullobj, ref _nullobj, ref _nullobj, ref _nullobj);  }  /// <summary>  /// 替換word中的文字  /// </summary>  /// <param name="strOld">查找的文字</param>  /// <param name="strNew">替換的文字</param>  public void Replace(string strOld, string strNew)  {   _app.Selection.Find.ClearFormatting();   _app.Selection.Find.Replacement.ClearFormatting();   _app.Selection.Find.Text = strOld;   _app.Selection.Find.Replacement.Text = strNew;   object objReplace = Microsoft.Office.Interop.Word.WdReplace.wdReplaceAll;   _app.Selection.Find.Execute(ref _nullobj, ref _nullobj, ref _nullobj,          ref _nullobj, ref _nullobj, ref _nullobj,          ref _nullobj, ref _nullobj, ref _nullobj,          ref _nullobj, ref objReplace, ref _nullobj,          ref _nullobj, ref _nullobj, ref _nullobj);  }  /// <summary>  /// 保存  /// </summary>  public void Save()  {   _doc.Save();  }  /// <summary>  /// 退出  /// </summary>  public void Dispose()  {   _doc.Close(ref _nullobj, ref _nullobj, ref _nullobj);   _app.Quit(ref _nullobj, ref _nullobj, ref _nullobj);  } }}

以上就是關(guān)于asp.net如何操作Word實(shí)現(xiàn)批量替換的全部代碼，希望對(duì)大家的學(xué)習(xí)有所幫助。
