How can I initialize the variable query  before try --catch statement. Please help

        {
            try
            {
                _logger.LogInformation($"Getting all comedians");
                var query = _db.Comedians
                            .OrderBy(c => c.LastName);
                //return query.ToArray();

            }
            catch(Exception ex)
            {

            }
          return query.ToArray(); // How can I return the variable query here

          
        }
