c# - 在 C# 中更改子文件夹的权限

Question

我正在编写一个 DLL 来更改文件夹和文件夹下所有内容的权限。下面是我现在拥有的代码。

当我调用 addPermissions() 时出现问题。它正确地设置了 dirName 文件夹和我后来在 dirName 下创建的任何文件夹的权限，但是当我添加权限时存在的任何文件夹都没有获得额外的权限。

我是否需要递归地设置所有子文件夹的权限？或者有没有办法用一两行代码来做到这一点？

public class Permissions
{
    public void addPermissions(string dirName, string username)
    {
        changePermissions(dirName, username, AccessControlType.Allow);
    }

    public void revokePermissions(string dirName, string username)
    {
        changePermissions(dirName, username, AccessControlType.Deny);
    }

    private void changePermissions(string dirName, string username, AccessControlType newPermission)
    {
        DirectoryInfo myDirectoryInfo = new DirectoryInfo(dirName);

        DirectorySecurity myDirectorySecurity = myDirectoryInfo.GetAccessControl();

        string user = System.Environment.UserDomainName + "\\" + username;

        myDirectorySecurity.AddAccessRule(new FileSystemAccessRule(
            user, 
            FileSystemRights.Read | FileSystemRights.Write | FileSystemRights.ExecuteFile | FileSystemRights.Delete, 
            InheritanceFlags.ContainerInherit | InheritanceFlags.ObjectInherit, 
            PropagationFlags.InheritOnly, 
            newPermission
        ));

        myDirectoryInfo.SetAccessControl(myDirectorySecurity);
    }
}

这个问题很老，但我一直在寻找同样的东西并找到了解决方案:

var dirInfo = new DirectoryInfo(dirName);
var dirSecurity = dirInfo.GetAccessControl();

// Add the DirectorySystemAccessRule to the security settings. 
dirSecurity.AddAccessRule(new FileSystemAccessRule(
    account, 
    rights, 
    InheritanceFlags.ContainerInherit | InheritanceFlags.ObjectInherit, 
    PropagationFlags.None, 
    AccessControlType.Allow));

// Set the new access settings.
dirInfo.SetAccessControl(dirSecurity);
