Try using below code, it is tested and working fine.

 var  query = new QueryExpression("organization")
                {
                    ColumnSet = new ColumnSet("blockedattachments", "maxuploadfilesize")
                };
                var record = service.RetrieveMultiple(query).Entities.FirstOrDefault();

                if (record != null)
                {
                    var blockedAttachments = record.GetAttributeValue<string>("blockedattachments");
                    var maxAttachmentSize = record.GetAttributeValue<int>("maxuploadfilesize");
                }
