All values in Redis are ultimately stored as a RedisValue type:
//"myvalue" here is implicitly converted to a RedisValue type
//The RedisValue type is rarely seen in practice.
db.StringSet("key", "aValue");
db.StringSet("key", 11021);
int i = (int)db.StringGet("key");
Or using StackExchange.Redis.Extensions:
db.Add("key", 11021);
int i = db.Get<int>("key");
