[英]Change permissions of folders
I want to change some folder permissions (set to Read-Only) to ReadWriteExecute! 我想将一些文件夹权限(设置为只读)更改为ReadWriteExecute!
I wrote this code, but the folder permission is still Read-Only: 我写了这段代码,但文件夹权限仍然是只读的:
private void ChangePermissions(string folder)
{
string userName = Environment.UserName;
FileSystemAccessRule accessRule = new FileSystemAccessRule(userName, FileSystemRights.FullControl, InheritanceFlags.ContainerInherit
| InheritanceFlags.ObjectInherit, PropagationFlags.None, AccessControlType.Allow);
DirectoryInfo directoryInfo = new DirectoryInfo(folder);
DirectorySecurity directorySec = directoryInfo.GetAccessControl();
directorySec.AddAccessRule(accessRule);
directoryInfo.SetAccessControl(directorySec);
}
If I want delete this directory with Directory.Delete(folder, true)
I get this error message: 如果我想用Directory.Delete(folder, true)
删除此目录,我收到此错误消息:
"Access to the path 'entries' is denied." “拒绝访问路径'条目'。”
Sure, the permissions are still Read-Only! 当然,权限仍然是只读的!
What is wrong here? 这有什么不对?
You could try something like this: 你可以尝试这样的事情:
var dirInfo = new DirectoryInfo(folder);
dirInfo.Attributes &= ~FileAttributes.ReadOnly;
This uses the bitwise logical AND operator (&=) to append to the existing Attributes property the inverse of FileAttributes.ReadOnly
(because ~
is bitwise NOT). 这使用按位逻辑AND运算符(&=)将现有的Attributes属性附加到FileAttributes.ReadOnly
的反转(因为~
是按位NOT)。
