从 C# 中的 Microsoft Word 文件中读取内容

Question

我尝试在 C# 中阅读 .docx 和 .txt ABC.docx 的内容是：

测试1

测试2

我的代码实际上读取了 ABC.docx 但一个问题是当数据存储在 sql server 中时输出是这样的：

下面是我的代码：

 void WalkDirectoryTree(System.IO.DirectoryInfo root)
    {
        //System.IO.FileInfo[] files = null;

        System.IO.DirectoryInfo[] subDirs = null;

        //need to add-in more extension file such as .doc,  .ppt, .xlsx
        //files = root.GetFiles("*.txt");


        var files = root.GetFiles().Where(a => a.Extension.Contains(".docx") || a.Extension.Contains(".txt"));

        //  files = new string[] { "*.txt", "*.docx" }
        //.SelectMany(i => root.GetFiles(i, SearchOption.AllDirectories))
        //.ToArray();

        //if file is not null, read filename & file extension
        if (files != null)
        {
            foreach (System.IO.FileInfo fi in files)
            {
                StringBuilder text = new StringBuilder();
                Microsoft.Office.Interop.Word.Application word = new Microsoft.Office.Interop.Word.Application();
                object miss = System.Reflection.Missing.Value;
                //object path = @"I:\def.docx";
                object path = fi.FullName;
                object readOnly = true;
                Microsoft.Office.Interop.Word.Document docs = word.Documents.Open(ref path, ref miss, ref readOnly, ref miss, ref miss, ref miss, ref miss, ref miss, ref miss, ref miss, ref miss, ref miss, ref miss, ref miss, ref miss, ref miss);

                for (int i = 0; i < docs.Paragraphs.Count; i++)
                {
                    text.Append(" \r\n " + docs.Paragraphs[i + 1].Range.Text.ToString());
                }


                //Get the full patch of the file extension
                string[] lines = System.IO.File.ReadAllLines(fi.FullName);
                //TextReader reader = new FilterReader(fi.FullName);
                //StreamReader m = new StreamReader(fi.FullName);



                foreach (string line in lines)
                {

                    String[] substrings = fi.FullName.Split('\\');
                    string strFileName = string.Empty;
                    string strFileExtension = string.Empty;


                    if (substrings.Length > 0)
                    {
                        strFileName = substrings[ substrings.Length -1 ];
                        if( !string.IsNullOrEmpty(strFileName) )
                        {
                            string[] extensionSplit = strFileName.Split('.');
                            if (extensionSplit.Length > 0)
                            {
                                strFileExtension = extensionSplit[extensionSplit.Length - 1];
                            }
                        }
                    }
                    else
                    {
                        strFileName = fi.FullName;
                    }

                     InsertData(strFileName, line.Replace("'",""),  fi.FullName,strFileExtension);
                }
            }

            //After searched from root, continue search from subDirectories
            subDirs = root.GetDirectories();

            #region Exclude all the hidden files from drives
            foreach (System.IO.DirectoryInfo dirInfo in subDirs)
            {
                if ((dirInfo.Attributes & FileAttributes.Hidden) == 0)
                {
                    WalkDirectoryTree(dirInfo);
                }
            }
            #endregion
        }
    }

请指教如何在 sql server 中存储。 谢谢。

Answer 1

将 Word 文档数据保存为数据库中的 Base64 字符串。

使用文档的base64String，不仅可以保存文档，还可以在稍后阶段打开它（通过转换回来）。

将此结果保存到数据库中；

Public string GetDocumentBinary()
    {
        string docPath = "DocumentPath";
        byte[] binarydata = File.ReadAllBytes(docPath);
        base64 = System.Convert.ToBase64String(binarydata, 0, binarydata.Length);
        return base64;
    }

然后当您需要显示文档时，将其转换回保存到磁盘（可选）；

Public void SaveBinaryAsDocument(string filePath, string base64String)
    {
        Byte[] bytes = Convert.FromBase64String(base64String);
        File.WriteAllBytes(filePath, bytes);
    }
