c# - 如何删除包含文件的文件夹？

Question

我想从我的程序中删除包含或不包含文件/文件夹的文件夹。

代码:

    static void Main(string[] args)
    {
        List<string> foldersToDelete = new List<string>();

        foreach(var f in System.IO.Directory.GetDirectories(@"C:\Users\Public\MySpecialTempFolder"))
        {
            var dir = new DirectoryInfo(f);
            dir.Attributes = dir.Attributes & ~FileAttributes.ReadOnly;

            long size = GetDirectorySize(f);

            // delete folders less then 1 mb
            if (size < 1000000)
                foldersToDelete.Add(f);
        }

        foreach (var s in foldersToDelete)
            System.IO.Directory.Delete(s, true);
    }

    private static long GetDirectorySize(string folderPath)
    {
        DirectoryInfo di = new DirectoryInfo(folderPath);
        return di.EnumerateFiles("*.*", SearchOption.AllDirectories).Sum(fi => fi.Length);
    }

但是...当我运行它时，我得到拒绝访问。怎么了，我可以通过右键单击文件夹并在那里删除它然后手动执行此操作

尝试使用 Visual Basic 删除:

var directory = new DirectoryInfo(targetDir);
if (directory.Exists)
{
    Microsoft.VisualBasic.FileIO.FileSystem.DeleteDirectory(targetDir, Microsoft.VisualBasic.FileIO.DeleteDirectoryOption.DeleteAllContents);
}

来自 File.Delete Access to the path is denied
