Remove/Delete all/one item from StackExchange.Redis cache

Question

I am using StackExchange.Redis client with Azure Redis Cache Service. Here is my class,

public class RedisCacheService : ICacheService
{
    private readonly ISe         


        

Answer 1

To remove a single item:

_cache.KeyDelete(key);

To remove all involves the FLUSHDB or FLUSHALL redis command; both are available in StackExchange.Redis; but, for reasons discussed here, they are not on the IDatabase API (because: they affect servers, not logical databases).

As per the "So how do I use them?" on that page:

server.FlushDatabase(); // to wipe a single database, 0 by default
server.FlushAllDatabases(); // to wipe all databases

(quite possibly after using GetEndpoints() on the multiplexer)
