azure之从 StackExchange.Redis 缓存中删除/删除所有/一项

我正在将 StackExchange.Redis 客户端与 Azure Redis 缓存服务结合使用。这是我的类(class)，

public class RedisCacheService : ICacheService 
{ 
    private readonly ISettings _settings; 
    private readonly IDatabase _cache; 
 
    public RedisCacheService(ISettings settings) 
    { 
        _settings = settings; 
        var connectionMultiplexer = ConnectionMultiplexer.Connect(settings.RedisConnection); 
        _cache = connectionMultiplexer.GetDatabase(); 
    } 
 
    public bool Exists(string key) 
    { 
        return _cache.KeyExists(key); 
    } 
 
    public void Save(string key, string value) 
    { 
        var ts = TimeSpan.FromMinutes(_settings.CacheTimeout); 
        _cache.StringSet(key, value, ts); 
    } 
 
    public string Get(string key) 
    { 
        return _cache.StringGet(key); 
    } 
 
    public void Remove(string key) 
    { 
        // How to remove one 
    } 
 
    public void Clear() 
    { 
        // How to remove all 
    } 
} 

更新:在 Marc 的帮助下，这是我的最后一个类

public class RedisCacheService : ICacheService 
{ 
    private readonly ISettings _settings; 
    private readonly IDatabase _cache; 
    private static ConnectionMultiplexer _connectionMultiplexer; 
 
    static RedisCacheService() 
    { 
        var connection = ConfigurationManager.AppSettings["RedisConnection"]; 
        _connectionMultiplexer = ConnectionMultiplexer.Connect(connection); 
    } 
 
    public RedisCacheService(ISettings settings) 
    { 
        _settings = settings; 
        _cache = _connectionMultiplexer.GetDatabase(); 
    } 
 
    public bool Exists(string key) 
    { 
        return _cache.KeyExists(key); 
    } 
 
    public void Save(string key, string value) 
    { 
        var ts = TimeSpan.FromMinutes(_settings.CacheTimeout); 
        _cache.StringSet(key, value, ts); 
    } 
 
    public string Get(string key) 
    { 
        return _cache.StringGet(key); 
    } 
 
    public void Remove(string key) 
    { 
        _cache.KeyDelete(key); 
    } 
 
    public void Clear() 
    { 
        var endpoints = _connectionMultiplexer.GetEndPoints(true); 
        foreach (var endpoint in endpoints) 
        { 
            var server = _connectionMultiplexer.GetServer(endpoint); 
            server.FlushAllDatabases();     
        } 
    } 
} 

现在我不知道如何从redis缓存中删除所有项目或单个项目。

请您参考如下方法:

要删除单个项目:

_cache.KeyDelete(key); 

要删除全部涉及FLUSHDB或FLUSHALL redis命令；两者都可以在 StackExchange.Redis 中使用；但是，for reasons discussed here ，它们不在 IDatabase API 上(因为:它们影响服务器，而不是逻辑数据库)。

根据“那么我该如何使用它们？”在该页面上:

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

(很可能在多路复用器上使用 GetEndpoints() 之后)
