如何在给定文档中查找字符串的位置或位置

Question

如何在给定文档中找到字符串的位置或位置。我有一个 word 文档，我想将它的所有单词和单词位置存储在数据库中，这就是为什么我需要找到单词的位置。

所以请告诉我如何在给定文档中找到单词或字符串的位置或位置。

我打算将 vb.net 或 c# 用于和 .doc 文档

嗯...我还没有找到更智能的解决方案 :-/ 但也许这对您有帮助...我们假设您的系统中安装了某些版本的 MS Office。

首先，您必须在项目中添加对名为“Microsoft Word ?* object library”的 Microsoft COM 组件的引用

*?它取决于您的 MS Office 版本

添加参考后，您可以测试此代码：

using System;
using System.Collections.Generic;
using System.Text;
using Word;

namespace ConsoleApplication1
{
    class Program
    {

        static void Main(string[] args)
        {

            // Find the full path of our document

            System.IO.FileInfo ExecutableFileInfo = new System.IO.FileInfo(System.Reflection.Assembly.GetEntryAssembly().Location);            
            object docFileName = System.IO.Path.Combine(ExecutableFileInfo.DirectoryName, "document.doc");

            // Create the needed Word.Application and Word.Document objects

            object nullObject = System.Reflection.Missing.Value;
            Word.Application application = new Word.ApplicationClass();
            Word.Document document = application.Documents.Open(ref docFileName, ref nullObject, ref nullObject, ref nullObject, ref nullObject, ref nullObject, ref nullObject, ref nullObject, ref nullObject, ref nullObject, ref nullObject, ref nullObject);


            string wholeTextContent = document.Content.Text; 
            wholeTextContent = wholeTextContent.Replace('\r', ' '); // Delete lines between paragraphs
            string[] splittedTextContent = wholeTextContent.Split(' '); // Get the separate words

            int index = 1;
            foreach (string singleWord in splittedTextContent)
            {
                if (singleWord.Trim().Length > 0) // We don´t need to store white spaces
                {
                    Console.WriteLine("Word: " + singleWord + "(position: " + index.ToString() + ")");
                    index++;
                }
            }

            // Dispose Word.Application and Word.Document objects resources

            document.Close(ref nullObject, ref nullObject, ref nullObject);
            application.Quit(ref nullObject, ref nullObject, ref nullObject);
            document = null;
            application = null;

            Console.ReadLine(); 
        }
    }
}

我会测试它，它看起来有效 =)
