如何将ConcurrentDictionary转换为字典？ [英] How can I convert a ConcurrentDictionary to a Dictionary?

问题描述

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

不允许在它们之间投射。那么我该怎么办？

解决方案

ConcurrentDictionary< K，V> 类实现 IDictionary< K，V> 界面，应该足以满足大多数要求。但是，如果您真的需要具体的 词典< K，V> ; ...

  var newDictionary = yourConcurrentDictionary.ToDictionary（kvp => kvp.Key，
 kvp => kvp.Value，
 yourConcurrentDictionary.Comparer）; 
 
 //或... 
 //替换您的实际键和值类型代替TKey和TValue 
 var newDictionary = new Dictionary< TKey，TValue>（yourConcurrentDictionary， yourConcurrentDictionary.Comparer）; 
  

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

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

解决方案

The ConcurrentDictionary<K,V> class implements the IDictionary<K,V> interface, which should be enough for most requirements. But if you really need a concrete Dictionary<K,V>...

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

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