从SharePoint读取文件时没有返回正确的值

Question

我使用下面的代码从sharepoint 2019年读取一个文件，返回值不是字符串。返回值示例:0\0\0(\u0001\0\u001e\0\0\0\0\0\0\0\0\0)

using (ClientContext clientContext = new ClientContext("http://sharepoint2019/sites/test/"))
        {
            KeywordQuery keywordQuery = new KeywordQuery(clientContext);
            keywordQuery.QueryText = "SharePoint";
            keywordQuery.EnablePhonetic = true;
            SearchExecutor searchExecutor = new SearchExecutor(clientContext);                
            ClientResult<ResultTableCollection> results = searchExecutor.ExecuteQuery(keywordQuery);
            clientContext.ExecuteQuery();
            foreach (var resultRow in results.Value[0].ResultRows)
            {
                Console.WriteLine("{0}: {1} ({2})", resultRow["Title"], resultRow["Path"], resultRow["Write"]);

                File file= clientContext.Web.GetFileByUrl(resultRow["Path"].ToString());
                var stream = file.OpenBinaryStream();
                clientContext.Load(file);
                clientContext.ExecuteQuery();

                FileInformation fileInformation = File.OpenBinaryDirect(clientContext, (string)file.ServerRelativeUrl);
                using (System.IO.StreamReader sr = new System.IO.StreamReader(fileInformation.Stream))
                {
                    // Read the stream to a string, and write the string to the console.
                   String line = sr.ReadToEnd();
                    Console.WriteLine(line);
                }


            }

        }

如果您正在读取一些文件，如Word (而不是txt文件)，则需要使用Open库读取Word中的字符串，filestream无法按预期返回真正的字符串：

使用Open (CSOpenXmlGetPlainText)获取Word文档的纯文本

从流中打开文字处理文档(Open )
