Question

我想做一些简单的事情。获取文件夹A的内容并将文件和文件夹移动到文件夹A中的文件夹中。然后隐藏文件夹A.

下面的代码是找不到hiddenTarget的例外。

Directory.Create(hiddenTarget) is not helping

必须有一种简单的方法来做到这一点。目前我正在尝试创建一个临时目录。将当前目录中的所有文件放入其中。然后将临时目录移动到当前目录。然后隐藏当前目录。

以下是有问题的代码..

string tempFolder = Path.Combine(Environment.ExpandEnvironmentVariables("%TEMP%"), "tempTarget");
//Directory.CreateDirectory(tempFolder);

Directory.Move(currentTarget, tempFolder);

string hiddenTarget = Path.Combine(currentTarget, @".bak");
//Directory.CreateDirectory(hiddenTarget);

Directory.Move(tempFolder, hiddenTarget);

DirectoryInfo di = new DirectoryInfo(currentTarget);
di.Attributes = FileAttributes.Directory | FileAttributes.Hidden;

首先，你有两个问题是你的隐藏目标不能以'。'开头。因为正如评论中指出的那样在NTFS中是非法的。

正如您所见，文件资源管理器不喜欢这种语法。

正如@Dour High Arch所指出的，这里是相关信息的链接：Naming Files, Paths, and Namespaces

您的下一个问题是该移动正在破坏原始目录结构。因此，您的步骤需要如下：

1）移动到临时目录，以避免两个进程（文件系统和您的进程）争用访问的任何问题。

2）由于第1步中的Directory.Move破坏了原始源目录。重新创建已销毁的源文件夹。

3）然后进入所需的嵌套文件夹。此移动操作将自动创建所需的子目录。步骤＃2是必需的，因为无论出于何种原因我还在查看Directory.Move无法在没有源目录的情况下自动创建结构。

        string currentTarget = @"C:\A";
        string hiddenTarget = @"C:\A\Subfolder";

        string tempTarget = @"C:\Temp";

        Directory.Move(currentTarget, tempTarget);
        Directory.CreateDirectory(currentTarget);
        Directory.Move(tempTarget, hiddenTarget);

        DirectoryInfo di = new DirectoryInfo(currentTarget);
        di.Attributes = FileAttributes.Directory | FileAttributes.Hidden;

从工程角度来看，如果您真的关心要移动的数据，那么您真的应该执行复制。它可能会更慢，但有助于防止任何可怕的事情发生在数据上。在创建这些目录之前，您应该先检查这些目录是否存在。此示例中的异常处理也至少也是如此。我在这里要强调的是处理正在小心移动的数据！

    static void Main(string[] args)
    {
        string sourceDir = @"C:\Src";
        string tempDir = @"C:\Temp";
        string destDir = Path.Combine(sourceDir, "Dest");

        // Could optionally check to verify that the temp directory already exists here and destroy it if it does.
        // Alternatively, pick a really unique name for the temp directory by using a GUID, Thread Id or something of that nature.
        // That way you can be sure it does not already exist.

        // Copy to temp, then destroy source files.
        CopyDirectory(sourceDir, tempDir);
        Directory.Delete(sourceDir, true);

        // Copy to dest
        CopyDirectory(tempDir, destDir);

        // Hide the source directory.
        DirectoryInfo di = new DirectoryInfo(sourceDir);
        di.Attributes = FileAttributes.Directory | FileAttributes.Hidden;

        // Clean up the temp directory that way copies of the files aren't sitting around.
        // NOTE: Be sure to do this last as if something goes wrong with the move the temp directory will still exist.
        Directory.Delete(tempDir, true);

    }

    /// <summary>
    /// Recursively copies all subdirectories.
    /// </summary>
    /// <param name="sourceDir">The source directory from which to copy.</param>
    /// <param name="destDir">The destination directory to copy content to.</param>
    static void CopyDirectory(string sourceDir, string destDir)
    {
        var sourceDirInfo = new DirectoryInfo(sourceDir);
        if (!sourceDirInfo.Exists)
        {
            throw new DirectoryNotFoundException($"Source directory does not exist or could not be found: '{sourceDir}'");
        }

        // If the destination directory doesn't exist, create it.
        if (!Directory.Exists(destDir))
        {
            Directory.CreateDirectory(destDir);
        }

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

        // Copy subdirectories
        DirectoryInfo[] subDirs = sourceDirInfo.GetDirectories();
        foreach (DirectoryInfo subdir in subDirs)
        {
            string tempPath = Path.Combine(destDir, subdir.Name);
            CopyDirectory(subdir.FullName, tempPath);
        }
    }
