无法设置文件夹的完全控制权限

Question

我正在尝试通过C＃将Full Control权限（用于NT服务帐户）添加到文件夹。但是，未设置权限，我在这里缺少什么？

var directoryInfo = new DirectoryInfo(@"C:\Test");
var directorySecurity = directoryInfo.GetAccessControl();

directorySecurity.AddAccessRule(new FileSystemAccessRule("NT Service\\FileMoverService",
    FileSystemRights.FullControl, AccessControlType.Allow));

directoryInfo.SetAccessControl(directorySecurity);

Answer 1

您需要指定继承标志：

directorySecurity.AddAccessRule(new FileSystemAccessRule(@"NT Service\FileMoverService",
    FileSystemRights.FullControl,
    InheritanceFlags.ContainerInherit | InheritanceFlags.ObjectInherit,
    PropagationFlags.None,
    AccessControlType.Allow));

Answer 2

方法GrantFullControl可用于为给定目录和用户设置Full Control权限。

private static void GrantFullControl(string directoryPath, string username)
{
    if (!Directory.Exists(directoryPath))
        return;

    var directorySecurity = Directory.GetAccessControl(directoryPath);
    directorySecurity.AddAccessRule(new FileSystemAccessRule(username, FileSystemRights.FullControl,
        InheritanceFlags.ContainerInherit | InheritanceFlags.ObjectInherit, PropagationFlags.None,
        AccessControlType.Allow));

    Directory.SetAccessControl(directoryPath, directorySecurity);
}

只需调用如下所示的方法即可。

GrantFullControl(@"C:\Test", @"NT Service\FileMoverService");
