问题描述

我使用[OutputCacheAttribute]缓存一些操作.一切正常.假设我将其Duration属性设置为1小时.但是我希望能够清除缓存的值.有可能吗?

I use [OutputCacheAttribute] to cache some actions. Everything works fine. Let's say I set its Duration property to 1 hour. But I want to be able to clear cached values. Is it possible?

推荐答案

查看[OutputCacheAttribute]源代码后，似乎唯一可行的解​​决方案是实现一个从MemoryCache派生的新类并将其设置为OutputCacheAttribute.ChildActionCache属性.此类将为所有缓存键使用一些自定义前缀，因此我将很容易找到它们(然后从缓存中删除).

After looking at [OutputCacheAttribute] source code, it seems that the only possible solution is to implement a new class derived from MemoryCache and set it OutputCacheAttribute.ChildActionCache property. This class will be use some custom prefix for all cached keys, so I'll be quite easy to find them (and then remove from cache).
