用于重命名的 C# DirectoryInfo.MoveTo 有时会抛出 IOException

Question

我正在尝试使用 DirectoryInfo.MoveTo() 重命名我刚刚将 Zip 存档解压缩到的目录。大多数情况下，该操作会抛出错误为 Access to the path '...' is denied. 的 IOException。有时，该操作有效，但我无法关联支持此操作的任何条件。我检查了许多论坛帖子和 Whosebug 问题，但我仍然无法正常工作。我确定它不是计算机权限。所有这些文件和文件夹都具有完整的 read/write 权限，我已经运行以管理员身份尝试了该程序。

这是我的代码：

// Compute directory names
string directoryPathWithPrefix = Path.Combine(this.OutputDirectory.FullName,
    "TEMP_ " + Path.GetFileNameWithoutExtension(compressedData.FullName));

string directoryPathWithoutPrefix = Path.Combine(this.OutputDirectory.FullName,
    Path.GetFileNameWithoutExtension(compressedData.FullName));

// Extract file to new directory
ZipFile.ExtractToDirectory(compressedData.FullName, directoryPathWithPrefix);

// Add tag for UploadId
File.Create(Path.Combine(directoryPathWithPrefix,
    upload.UploadId.ToString() + ".UPLOADID")).Close();

// Rename file
DirectoryInfo oldDir = new DirectoryInfo(directoryPathWithPrefix);
oldDir.MoveTo(directoryPathWithoutPrefix);

我试过使用 Process Explorer 来监视目录的句柄，但未能从中找到任何有用的数据。使用 Directory.Move() 或在 using 块内创建 ZipArchive 对象仍然会引发错误。

我真的被这个难住了。请帮忙。

澄清： 我是运行 Windows 7，这个程序是在 .NET 4.5

下构建的

这是我收到的错误：

System.IO.IOException occurred
  HResult=-2146232800

我终于弄明白了。 ZipFile.ExtractToDirectory() 存在一些奇怪的故障，当它完成提取时，不会释放对目录中文件的访问权限。为了解决这个问题，我更改了我的代码如下：

// 计算目录名字符串 directoryPathWithPrefix = Path.Combine(this.SeparatorInputDirectory.FullName, "TEMP_ " + Path.GetFileNameWithoutExtension(compressedFlightData.FullName));

string directoryPathWithoutPrefix = Path.Combine(this.SeparatorInputDirectory.FullName,
    Path.GetFileNameWithoutExtension(compressedFlightData.FullName));

string tempDirectoryPath = Path.Combine(TempDirectoryPath, Path.GetDirectoryName(directoryPathWithoutPrefix));

// Extract file to new directory in the separator input directory
ZipFile.ExtractToDirectory(compressedFlightData.FullName, tempDirectoryPath);

// Add tag for UploadId
File.Create(Path.Combine(tempDirectoryPath,
    upload.UploadId.ToString() + ".UPLOADID")).Close();

// Rename file to trigger separation
DirectoryCopy(tempDirectoryPath, directoryPathWithPrefix);
Directory.Move(directoryPathWithPrefix, directoryPathWithoutPrefix);

public static void DirectoryCopy(string sourceDirName, string destDirName)
{
    // Get the subdirectories for the specified directory.
    DirectoryInfo dir = new DirectoryInfo(sourceDirName);

    if (!dir.Exists)
    {
        throw new DirectoryNotFoundException(
            "Source directory does not exist or could not be found: "
            + sourceDirName);
    }

    DirectoryInfo[] dirs = dir.GetDirectories();
    // If the destination directory doesn't exist, create it.
    if (!Directory.Exists(destDirName))
    {
        Directory.CreateDirectory(destDirName);
    }

    // Get the files in the directory and copy them to the new location.
    FileInfo[] files = dir.GetFiles();
    foreach (FileInfo file in files)
    {
        string tempPath = Path.Combine(destDirName, file.Name);
        file.CopyTo(tempPath, false);
    }

    // Copy subdirectories and their contents to new location.
    foreach (DirectoryInfo subDir in dirs)
    {
        string tempPath = Path.Combine(destDirName, subDir.Name);
        DirectoryCopy(subDir.FullName, tempPath);
    }
}
