将IReliableDictionary转换为IList [英] Convert IReliableDictionary to IList

问题描述

我有一个IReliableDictionary，需要将字典中的项目带入IList以从我可靠的服务中退回.

I have an IReliableDictionary and need to take the items in the dictionary and move them in to an IList to return from my reliable service.

似乎我无法执行任何类型的.ToList，所以我确定我无法正确处理它.

It seems I can't do a .ToList of any kind, so I'm sure I'm approaching it wrong.

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(); ???

   ...
}

关于如何从字典中取出项目并将其放入列表的任何想法?

Any ideas on how to take the items from the dictionary and put them in to the list?

推荐答案

IReliableDictionary(就像IDictionary一样)是IEnumerable键值对，因此您可以这样操作:

IReliableDictionary (just like an IDictionary) is IEnumerable of key value pairs, so you can go this way:

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;
    }
