//cli.Serialize = obj => JsonConvert.SerializeObject(obj);
//cli.Deserialize = (json, type) => JsonConvert.DeserializeObject(json, type);
cli.Notice += (s, e) => Console.WriteLine(e.Log); //print command log
cli.Set("key1", "value1");
cli.MSet("key1", "value1", "key2", "value2");
string value1 = cli.Get("key1");
string[] vals = cli.MGet("key1", "key2");Supports strings, hashes, lists, sets, sorted sets, bitmaps, hyperloglogs, geo, streams And BloomFilter.
| Parameter | Default | Explain |

| user | <empty> | Redis server username, requires redis-server 6.0 |
| password | <empty> | Redis server password |
| defaultDatabase | 0 | Redis server database |
| max poolsize | 100 | Connection max pool size |
| min poolsize | 5 | Connection min pool size |
| idleTimeout | 20000 | Idle time of elements in the connection pool (MS), suitable for connecting to remote redis server |
| connectTimeout | 10000 | Connection timeout (MS) |
| receiveTimeout | 10000 | Receive timeout (MS) |
| sendTimeout | 10000 | Send timeout (MS) |
| encoding | utf-8 | string charset |
