title: .NET How to change Folder/File permission or Access rights?
body: <p>I want to prevent user from moving/renaming/deleting folders but navigating inside the folder to see its sub folders and files; Also, the code can create sub folders/files inside the folder after setting these access rights.
  For files, i want also to prevent user to update/move/rename/delete but the app can do this. I played with the DirectorySecurity but i can't produce the desired results.</p>
  
  <pre><code>var directoryInfo = new DirectoryInfo(path);
              var directorySecurity = directoryInfo.GetAccessControl();
  
              var windowsIdentity = System.Security.Principal.WindowsIdentity.GetCurrent();
              if (windowsIdentity != null)
              {
                  var userName = windowsIdentity.Name;
                  directorySecurity.AddAccessRule(new FileSystemAccessRule(userName,
                      FileSystemRights.FullControl, AccessControlType.Deny));
                  directorySecurity.AddAccessRule(new FileSystemAccessRule(userName,
                      FileSystemRights.Read | FileSystemRights.ListDirectory | FileSystemRights.CreateDirectories | FileSystemRights.CreateFiles , AccessControlType.Allow));
                  directoryInfo.SetAccessControl(directorySecurity);
              }
  </code></pre>
