   if (!ModelState.IsValid) { string error = string.Empty; foreach (var key in ModelState.Keys) { var state = ModelState[key]; if (state.Errors.Any()) { error = state.Errors.First().ErrorMessage; break; } } return ApiResponse(new ReturnMessage() { Status = ResultStatus.Failed, Message = error }); }
