c# - 在 C# 中从 SortedSet 中删除元素

Question

我试图从 Redis 排序列表中删除一个元素但没有成功

public bool Delete(int id)
        {
            try
            {
                var redisManager = new RedisManagerPool(Global.RedisConnector);
                using (var redis = redisManager.GetClient())
                {
                    var entities = redis.As<BookingRequestModel>();
                    var list = entities.SortedSets["BookingRequests"].GetAll();
     //count = 320
                    var model = list.First(z=>z.Id == id);
                    list.Remove(model);
           //count 319 - however when I refresh the page I still see my old data in grid ...
                    entities.Save();                  
                    return true;
                }
            }
            catch (Exception ex)
            {
                return false;
            }
        }

也试过这样的:

 public bool Delete(int id)
        {
            try
            {
                var redisManager = new RedisManagerPool(Global.RedisConnector);
                using (var redis = redisManager.GetClient())
                {
                    var entities = redis.As<BookingRequestModel>();
                    var list = entities.SortedSets["BookingRequests"];
                    var model = list.First(z=>z.Id == id);
                    var result = entities.RemoveItemFromSortedSet(list, model); // result is false                  
                    entities.Save();                  
                    return true;
                }
            }
            catch (Exception ex)
            {
                return false;
            }
        }

正如我在那里评论的那样，从网格中删除旧数据后，我仍然可以看到它们。

你能帮我解决这个问题吗？

不明白为什么，但这是有效的:

public bool Delete(int id)
        {
            try
            {
                var redisManager = new RedisManagerPool(Global.RedisConnector);
                using (var redis = redisManager.GetClient())
                {                                   
                    var items = redis.GetAllItemsFromSortedSet("BookingRequests");
                    foreach (var item in items)
                    {
                        var dto = item.FromJson<BookingRequestModel>();
                        if (dto.Id == id)
                        {
                            redis.RemoveItemFromSortedSet("BookingRequests", item);
                            break;
                        }
                    }
                    return true;
                }
            }
            catch (Exception ex)
            {
                return false;
            }
        }
