C#

public override FileManagerFilePermissions GetFilePermissions(FileManagerFile file) {
    int fileId = int.Parse(file.Id);
    Permissions permissions = Data.PermissionsSet.FirstOrDefault(p => p.Item.Id == fileId);
    if(permissions == null)
        return FileManagerFilePermissions.Default;
    return GetFilePermissionsInternal(permissions);
}

public override FileManagerFolderPermissions GetFolderPermissions(FileManagerFolder folder) {
    if(string.IsNullOrEmpty(folder.RelativeName))
        return FileManagerFolderPermissions.Default;
    int folderId = int.Parse(folder.Id);
    Permissions permissions = Data.PermissionsSet.FirstOrDefault(p => p.Item.Id == folderId);
    if(permissions == null)
        return FileManagerFolderPermissions.Default;
    return GetFolderPermissionsInternal(permissions);
}

FileManagerFilePermissions GetFilePermissionsInternal(Permissions permissions) {
    return (permissions.Delete ? FileManagerFilePermissions.Delete : FileManagerFilePermissions.Default)
        | (permissions.Move ? FileManagerFilePermissions.Move : FileManagerFilePermissions.Default)
        | (permissions.Copy ? FileManagerFilePermissions.Copy : FileManagerFilePermissions.Default)
        | (permissions.Rename ? FileManagerFilePermissions.Rename : FileManagerFilePermissions.Default)
        | (permissions.Download ? FileManagerFilePermissions.Download : FileManagerFilePermissions.Default);
}

FileManagerFolderPermissions GetFolderPermissionsInternal(Permissions permissions) {
    return (permissions.Delete ? FileManagerFolderPermissions.Delete : FileManagerFolderPermissions.Default)
        | (permissions.Move ? FileManagerFolderPermissions.Move : FileManagerFolderPermissions.Default)
        | (permissions.Copy ? FileManagerFolderPermissions.Copy : FileManagerFolderPermissions.Default)
        | (permissions.Rename ? FileManagerFolderPermissions.Rename : FileManagerFolderPermissions.Default)
