.Net中弱字典的良好实现 [英] Good implementation of weak dictionary in .Net

问题描述

在哪里可以找到使用弱引用的 IDictionary 的良好实现？

字典应该只保留或者我应该自己写？

解决方案

ConditionalWeakTable Class 使用弱键，一旦在表外没有其他对键的引用，就会自动删除键/值输入。

Where can I find good implementation of IDictionary which uses weak references inside?

Dictionary should be holding only weak references to values and eventually clean up itself of dead references.

Or should I just write it myself?

解决方案

ConditionalWeakTable Class uses weak keys and automatically removes the key/value entry as soon as no other references to a key exist outside the table.
