asp.net operation Word to implement batch substitution _ Practical Tips

First, you introduce the Microsoft.Office.Interop.Word component, which appears in COM after you install Office.

The code is as follows

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 _a
  pp
  Private Microsoft.office.interop.word._document _doc;
  Object _nullobj = System.Reflection.Missing.Value; <summary>///Closes word process///</summary> public void Killwinword () {var p = Process.getprocessesb
   Yname ("Winword"); if (P.any ()) p[0].
  Kill (); ///<summary>///Open Word document///</summary>///<param name= "FilePath" ></param> public V
   OID 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 _NULLOB J, ref _nullobj, ref _nullobj, ref _nullobj, ref _nullobj, ref _nullobj, ref _nullobj, ref _nullobj, ref _nullobj, ref _nullobj); ///<summary>///replaces text in Word///</summary>///<param name= "Strold" > found text </param>// /<param name= "strnew" > replaced text </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 _NULLOB
  J, ref _nullobj, ref _nullobj); ///<summary>///Save///</summary> public void Save () {_doc.
  Save ();
}///<summary>///exit///</summary> public void Dispose () {   _doc.
   Close (ref _nullobj, ref _nullobj, ref _nullobj); _app.
  Quit (ref _nullobj, ref _nullobj, ref _nullobj);
 }
 }
}

The above is about asp.net how to operate word to achieve bulk replacement of all the code, I hope to help you learn.
