拒絕訪問路徑-C＃Directory.Move

Question

我正在開發一個項目，該項目將解壓縮文件夾，遍歷提取的文件夾中的文件並將上傳的數據上傳到數據庫，並將zip和文件夾同時移動到另一個目錄。 我在移動提取的文件夾時遇到問題。

Message "Access to the path 'Insurance_Documents\\Test_2017' is denied."    string

我最初的直覺是這是一個權限問題。 但是，我檢查了許可，一切看起來都不錯。 此外，由於程序會創建目錄本身，因此導致權限似乎不太合邏輯。

接下來，在瀏覽了一下Internet之后，我以為我的uploadReportData（）函數可能已經鎖定了文件（它確實利用了using語句，但是我認為在文件仍被鎖定的過程中可能仍然存在“滯后”）。 作為響應，我將Thread.sleep語句放入代碼中沒有成功。 該程序可以很好地移動Zip文件夾。 麻煩的是“普通”目錄。

Program.cs

    using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using UploadInsurance.Helpers;

namespace UploadInsurance
{
    class Program
    {
        static void Main(string[] args)
        {
            try
            {
                ZipHelper.processDirectory();
            }
            catch (Exception ex)
            {
                Console.WriteLine(ex.Message + "\n" + ex.StackTrace);
            }
            finally {
                Console.Read();

            }

        }
    }
}

ZipHelper.cs（部分）

     static class ZipHelper
    {
        private static String BASE_DIRECTORY = @"Insurance_Documents\";
        private static String OLD_ZIPS = @"Insurance_Documents\Old\";
        private static String EXTRACTED_FOLDERS = @"Insurance_Documents\Inserted\";

        private static List<String> zipFileList = new List<string>();


        private static void getZipFiles()
        {
            zipFileList = Directory.GetFiles(BASE_DIRECTORY, "*.zip").ToList();

        }

        private static void processZipFiles()
        {
            String zipFolderName = "";
            String reportFolderName = "";


        foreach (String file in zipFileList)
        {
           folderName = Path.GetFileNameWithoutExtension(file);
            reportFolderPath= BASE_DIRECTORY + folderName;
            ZipFile.ExtractToDirectory(file, reportFolderPath);

            uploadReportData(reportFolderPath);             
            Directory.Move(file, OLD_ZIPS + Path.GetFileName(file));
            Thread.Sleep(2000);
            Directory.Move(reportFolderPath + "//", EXTRACTED_FOLDERS + folderName);
        }
    }
 ... // MORE CODE HERE, INCLUDE uploadReportData function .. ///

    public static void processDirectory()
        {
            ZipHelper.getZipFiles();
            ZipHelper.processZipFiles();         

        }

我也嘗試改變

  Directory.Move(reportFolderPath, EXTRACTED_FOLDERS + folderName);

至

  Directory.Move(reportFolderPath + "//", EXTRACTED_FOLDERS + folderName);

但仍然收到錯誤。 我嘗試下載並使用ProcessExplorer（如此處另一個答案所述），唯一訪問該目錄的進程是我的程序本身。

任何幫助將非常感激。

很抱歉，但問題可能出在以下代碼中：

我的直覺是您需要關閉/處置CsvFileReader對象。 要釋放的文件流將被鎖定，直到您釋放它為止。
