我工作的一個項目，是通過提取的文件夾中的文件解壓縮文件夾，循環並上傳數據到數據庫中，同時移動壓縮和文件夾到另一個目錄。我遇到了移動解壓縮文件夾的問題。訪問路徑被拒絕 - C＃Directory.Move
Message "Access to the path 'Insurance_Documents\\Test_2017' is denied." string
我最初的直覺是它是一個權限問題。但是，我檢查了許可，並且一切看起來不錯;另外，當程序創建目錄本身時，權限似乎並不合乎邏輯。
接下來，在環顧了一下互聯網後，我想我的uploadReportData（）函數可能已經鎖定了文件（它確實利用了使用語句，但我認爲文件可能仍然存在「滯後」仍然鎖定）。作爲迴應，我將Thread.sleep語句放入代碼中，但沒有成功。該程序移動Zip文件夾就好了;這是「正常」的目錄，給我帶來麻煩。
的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（局部的）
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();
}
我還試圖改變
Directory.Move(reportFolderPath, EXTRACTED_FOLDERS + folderName);
到
Directory.Move(reportFolderPath + "//", EXTRACTED_FOLDERS + folderName);
但仍收到錯誤。我嘗試下載並使用ProcessExplorer（如此處另一個答案中所述），訪問該目錄的唯一過程就是我的程序本身。
任何幫助將不勝感激。

我的道歉長度，但我懷疑問題可能在於下面的代碼：

{

如果您運行的帳戶下的程序，而是嘗試創建與代碼的文件夾，並手動做運動，而程序仍在運行。如果你不能手動移動它，那麼你自己的程序可能會鎖定一個文件或其他東西。 – CodingYoshi
感謝您的建議。這確實是我的程序，但我不確定代碼的哪一部分將其鎖定。我會發布我的uploadReportData函數，因爲我懷疑它可能是。非常感謝。 – KellyMarchewa
這可能是通過'using'使用CsvFileReader，像'使用（CsvFileReader讀卡器=新CsvFileReader（兒童））是一個好主意 {...}'，以確保文件句柄被釋放的使用條款之外。 –
