azure-service-fabric - 将 IReliableDictionary 转换为 IList

Question

我有一个 IReliableDictionary 并且需要获取字典中的项目并将它们移动到 IList 以从我的可靠服务中返回。

看来我不能做任何类型的 .ToList ，所以我确定我做错了。

public async Task<IList<CustomerOrderItem>> GetOrdersAsync()
{   


   IReliableDictionary<CustomerOrderItemId, CustomerOrderItem> orderItems =
   await this.StateManager.GetOrAddAsync<IReliableDictionary<CustomerOrderItemId, CustomerOrderItem>>(CustomerOrderItemDictionaryName);

   Dictionary<KeyValuePair<CustomerOrderItemId, CustomerOrderItem>, KeyValuePair<CustomerOrderItemId, CustomerOrderItem>> items = orderItems.ToDictionary(v => v);

   IList<CustomerOrderItem> list = orderItems.ToList(); ???

   ...
}

关于如何从字典中获取项目并将它们放入列表的任何想法？

Answer 1

IReliableDictionary<K,V>实现IEnumerable<KeyValuePair<K, V>>，所以你可以做一个ToList.

也许确保命名空间被导入。

Answer 2

IReliableDictionary（就像 IDictionary 一样）是键值对的 IEnumerable，所以你可以这样：

public async Task<IList<CustomerOrderItem>> GetOrdersAsync()
    {
        IReliableDictionary<CustomerOrderItemId, CustomerOrderItem> orderItems =
        await this.StateManager.GetOrAddAsync<IReliableDictionary<CustomerOrderItemId, CustomerOrderItem>>(CustomerOrderItemDictionaryName);

        var list = orderItems.Select(kvp => kvp.Value).ToList();
        return list;
    }
