我怎么能转换ConcurrentDictionary到字典？

问题描述

我有一个ConcurrentDictionary对象，我想设置一个Dictionary对象。

I have a ConcurrentDictionary object that I would like to set to a Dictionary object.

不允许它们之间的铸造。所以，我怎么办呢？

Casting between them is not allowed. So how do I do it?

推荐答案

的<$c$c>ConcurrentDictionary<K,V>类实现 的IDictionary＆LT; K，V＆GT; 接口，这应该足以满足大多数要求。但是，如果你真的需要一个具体的<$c$c>Dictionary<K,V>...

var newDictionary = yourConcurrentDictionary.ToDictionary(kvp => kvp.Key,
                                                          kvp => kvp.Value);

// or...
// substitute your actual key and value types in place of TKey and TValue
var newDictionary = new Dictionary<TKey, TValue>(yourConcurrentDictionary);
