asp.net操作Word实现批量替换

首先引入Microsoft.Office.Interop.Word组件，该组件在安装完office后在COM中出现。

代码如下

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>/// 关闭Word进程/// </summary>public void KillWinword（）{ var p = Process.GetProcessesByName（"WINWORD"）; if （p.Any（）） p[0].Kill（）;}/// <summary>/// 打开word文档/// </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>/// 替换word中的文字/// </summary>/// <param name="strOld">查找的文字</param>/// <param name="strNew">替换的文字</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）;} }}
