我正在开发一个项目，即解压缩文件夹，循环解压缩文件夹中的文件并将数据上传到数据库，然后将zip文件夹和文件夹移动到另一个目录。我在移动提取的文件夹时遇到了问题。
Message "Access to the path 'Insurance_Documents\\Test_2017' is denied." string
我最初的直觉是这是一个许可问题。但是，我检查了许可，一切看起来都不错;另外，由于程序自己创建目录，因此将权限作为原因似乎不合逻辑。
接下来，在浏览了一下互联网之后，我认为我的uploadReportData（）函数可能已经锁定了文件（它确实利用了使用语句，但我认为可能仍然存在“滞后”期间文件仍然存在锁定）。作为回应，我将Thread.sleep语句放在我的代码中但没有成功。该程序移动Zip文件夹就好了;这是给我带来麻烦的“正常”目录。
Program.cs的
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();
}
我也尝试过改变
Directory.Move(reportFolderPath, EXTRACTED_FOLDERS + folderName);
到
Directory.Move(reportFolderPath + "//", EXTRACTED_FOLDERS + folderName);
但仍然收到错误。我尝试下载并使用ProcessExplorer（如此处的另一个答案中所述），访问该目录的唯一进程是我的程序本身。
非常感谢任何帮助。

我为篇幅道歉，但我怀疑问题可能在于下面的代码：

我的预感说你需要关闭/处置CsvFileReader对象。任何要文件的流都将锁定，直到您将其释放。
