我成功地能够删除只读使用以下code段属性上的一个文件：

I was successfully able to remove read only attribute on a file using the following code snippet:

在main.cs

FileSystemInfo[] sqlParentFileSystemInfo = dirInfo.GetFileSystemInfos();

foreach (var childFolderOrFile in sqlParentFileSystemInfo)
{
        RemoveReadOnlyFlag(childFolderOrFile);
}

private static void RemoveReadOnlyFlag(FileSystemInfo fileSystemInfo)
{
fileSystemInfo.Attributes = FileAttributes.Normal;
var di = fileSystemInfo as DirectoryInfo;

if (di != null)
{
foreach (var dirInfo in di.GetFileSystemInfos())
      RemoveReadOnlyFlag(dirInfo);
}
}

不幸的是，这并不上的文件夹的工作。运行code后，当我去到该文件夹​​，右击并做性能，这里是我所看到的：

Unfortunately, this doesn't work on the folders. After running the code, when I go to the folder, right click and do properties, here's what I see:

只读标志仍在检查，虽然它从它下面的文件中删除它。这会导致进程失败删除此文件夹。当我手动删除标志，并重新运行该程序（BAT文件），它能够删除的文件（让我知道这是不是与bat文件的问题）

The read only flag is still checked although it removed it from files underneath it. This causes a process to fail deleting this folder. When I manually remove the flag and rerun the process (a bat file), it's able to delete the file (so I know this is not an issue with the bat file)

如何删除这个标记在C＃？

推荐答案

您也可以做类似下面的递归清晰只读（和归档等）指定的父目录中的所有目录和文件：

You could also do something like the following to recursively clear readonly (and archive, etc.) for all directories and files within a specified parent directory:

private void ClearReadOnly(DirectoryInfo parentDirectory)
{
    if(parentDirectory != null)
    {
        parentDirectory.Attributes = FileAttributes.Normal;
        foreach (FileInfo fi in parentDirectory.GetFiles())
        {
            fi.Attributes = FileAttributes.Normal;
        }
        foreach (DirectoryInfo di in parentDirectory.GetDirectories())
        {
            ClearReadOnly(di);
        }
    }
}

您可以因此称此像这样：

You can therefore call this like so:

public void Main()
{
    DirectoryInfo parentDirectoryInfo = new DirectoryInfo(@"c:test");
    ClearReadOnly(parentDirectoryInfo);
}
