我正在处理一个项目，该项目是为了解压缩文件夹，循环浏览提取的文件夹中的文件，然后将数据上传到数据库，然后将zip和文件文件夹移至另一个目录。我遇到了移动提取的文件夹的问题。
Message "Access to the path 'Insurance_Documents\Test_2017' is denied." string
我最初的本能是这是一个许可问题。但是，我检查了许可，看上去都不错。此外，由于该程序创建了目录本身，因此权限成为原因似乎并不是很合乎逻辑的。
接下来，在互联网上浏览了一点之后，我以为我的uploadreportdata（）函数可能一直在锁定文件（它确实使用语句使用了，但是我认为可能仍然有一个"滞后"锁定）。作为回应，我将thread.sleep语句放在我的代码中而没有成功。该程序将Zip文件夹移动恰到好处。正是"正常"目录给我带来麻烦。
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_DocumentsOld";
private static String EXTRACTED_FOLDERS = @"Insurance_DocumentsInserted";
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();
}
我也尝试更改
Directory.Move(reportFolderPath, EXTRACTED_FOLDERS + folderName);
to
Directory.Move(reportFolderPath + "//", EXTRACTED_FOLDERS + folderName);
，但仍然收到错误。我尝试下载和使用ProcessExplorer（如在此处的另一个答案中指出），而访问该目录本身的唯一过程是我的程序。
任何帮助都将不胜感激。

我为这一长度表示歉意，但我怀疑问题可能在以下代码中：

我的直觉说您需要关闭/处置CSVFILEREDER对象。任何要文件的流将锁定直到您发布。
