Redis Stack Exchange how to delete or get keys by pattern

Question

I installed Stack Exchange redis client in C#. I can only delete one key or array of keys but I don\'t know how to delete keys with prefix. Or another solution can be first

Answer 1

You can do as the following to batch delete items from redis cache. (StackExchange.Redis.StrongName v1.0.488)

foreach (var ep in _muxer.GetEndPoints())
{
    var server = _muxer.GetServer(ep);
    var keys = server.Keys(database: _redisDatabase, pattern: pattern + "*").ToArray();
    _db.KeyDeleteAsync(keys);
}

_muxer is instance of ConnectionMultiplexer

It does not delete by pattern as you asked but much faster than deleting each key separately.
