You don't need to serialize it by hand. Just return the list directly:

public IEnumerable<Test> GetData(){
  List<Test> result = new List<Test>();
  // Fill data from Database
  return result;
}

Or better:

public IActionResult GetData(){
  List<Test> result = new List<Test>();
  // Fill data from Database
  return Ok(result);
}
