Grant NTFS Permissions to a Domain Group using C#
Coupled with creating a network file share, you need to also ensure NTFS permissions are not more restrictive than the permissions you create on your share. Otherwise, they will trump those permissions and your file share will be half done. The least restrictive permissions always win. See technet for more details on the security model.
Using a mix of the Security.Principal and Security.AccessControl .NET Classes you can couple this with your file share create class and get a complete set up of a file share; or, just use it to set NTFS permissions without all the file share portions in the previous post to set NTFS permissions on their own.
using System.Security.Principal; using System.Security.AccessControl; public static void GrantNTFSPermissions(string FolderPath, string Domain, string Group) { // Create a new DirectoryInfo object. DirectoryInfo directoryInfo = new DirectoryInfo(FolderPath); // Get a DirectorySecurity object that represents the // current security settings. DirectorySecurity directorySecurity = directoryInfo.GetAccessControl(); // Add the FileSystemAccessRule to the security settings. directorySecurity.AddAccessRule( new FileSystemAccessRule( new NTAccount(Domain, Group), FileSystemRights.Modify | FileSystemRights.ReadAndExecute | FileSystemRights.ListDirectory | FileSystemRights.Read | FileSystemRights.Write, InheritanceFlags.ContainerInherit | InheritanceFlags.ObjectInherit, PropagationFlags.None, AccessControlType.Allow) ); // Set the new access settings. directoryInfo.SetAccessControl(directorySecurity); }
Important Note: Passing mulitple values separated with a “|” to the FileSystemAccessRule class constructor’s parameters, allows you to set multiple options at once over mutliple calls/rewrites.
