如何在迭代时替换字典中键的值？

解决方案

您无需迭代更改字典。

尝试

 dict.Remove（keyToUpdate）; 
 dict.Add（newKey， value ）; 

在迭代它时，您将无法更改集合。

一种方法是创建一个临时的键值对列表，遍历此列表并根据需要更改密钥。 / blockquote>

解决方案

You don't need to iterate to change the dictionary.
Try

dict.Remove(keyToUpdate);
dict.Add(newKey, value);

You will not be able to change the collection while you are iterating through it.
A way out is to create a temporary list of key value pairs, iterate through this list and change the key as appropriate.

See this post to help you,http://stackoverflow.com/questions/6499334/best-way-to-change-dictionary-key[^], you can't rename keys once that have been added to a Dictionary, first remove then add a new.
