C# 从Redis检索多把钥匙时死锁

我试图使用StackExchangeClient并行地向redis获取此查询的结果，但不知何故，我在死锁中运行，不确定在哪里

检索数据的方法：

public LiveData Get(string sessionId)
{
    return GetAsync(sessionId).Result;
}

private async Task<LiveData> GetAsync(string sessionId)
{
    var basketTask = GetBasketAsync(sessionId);
    var historyTask = GetHistoryAsync(sessionId);
    var capturedDataTask = GetCapturedDataAsync(sessionId);

    var basket = await basketTask;
    var history = await historyTask;
    var capturedData = await capturedDataTask;

    return new LiveData
    {
        Basket = basket.IsNullOrEmpty
            ? new List<Product>()
            : JsonConvert.DeserializeObject<List<Product>>(basket),
        History = history.Select(cachedProduct
            => JsonConvert.DeserializeObject<Product>(cachedProduct.Value.ToString())).ToList(),
        CapturedData = capturedData.ToDictionary<HashEntry, string, object>(
            hash => hash.Name, hash => JsonConvert.DeserializeObject(hash.Value))
    };
}

从redis获取缓存数据的方法有：

private async Task<RedisValue> GetBasketAsync(string key)
{
    key = $"{key}{BasketSuffix}";
    var redisDb = RedisConnection.Connection.GetDatabase();
    redisDb.KeyExpireAsync(key, _expire);

    return await redisDb.StringGetAsync(key);
}

private async Task<HashEntry[]> GetHistoryAsync(string key)
{
    key = $"{key}{HistorySuffix}";
    var redisDb = RedisConnection.Connection.GetDatabase();
    redisDb.KeyExpireAsync(key, _expire);

    return await redisDb.HashGetAllAsync(key);
}

private async Task<HashEntry[]> GetCapturedDataAsync(string key)
{
    key = $"{key}{CapturedDataSuffix}";
    var redisDb = RedisConnection.Connection.GetDatabase();
    redisDb.KeyExpireAsync(key, _expire);

    return await redisDb.HashGetAllAsync(key);
}

我认为这样调用KeyExpireAsync很好，只是因为可以触发并忘记，但不确定这是否相关，我甚至尝试过删除它，但它仍然被阻止

死锁的来源是以下代码片段：

public LiveData Get(string sessionId)
{
    return GetAsync(sessionId).Result;
}

相反，请始终以正确的方式异步调用它：

public async Task<LiveData> Get(string sessionId)
{
    return await GetAsync(sessionId);
}

我理解您在.KeyExpireAsync调用中不使用wait关键字的想法，但如果我正在编写此代码，我肯定会像我演示的那样等待它。这是一个代码的气味有火灾和忘记，可以很容易地避免

async Task<RedisValue> GetBasketAsync(string key)
{
    key = $"{key}{BasketSuffix}";
    var redisDb = RedisConnection.Connection.GetDatabase();
    await redisDb.KeyExpireAsync(key, _expire);

    return await redisDb.StringGetAsync(key);
}
