ASP.Net的AppFabric缓存缺失冲洗/清除和计数/ getCount方法可？

本文介绍了ASP.Net的AppFabric缓存缺失冲洗/清除和计数/ getCount方法可？的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我试图用EntLib的解决方案转换为使用AppFabric缓存。通过几扩展方法的帮助，这是一个相当无痛苦的过程。

I am trying to convert a solution using EntLib into using AppFabric caching. By help of a few extension methods this is a fairly pain-free process.

扩展方法我用：

public static bool Contains(this DataCache dataCache, string key) { return dataCache.Get(key) != null; } public static object GetData(this DataCache dataCache, string key) { return dataCache.Get(key); }

但也有EntLib的两个特点，我觉得很难转换。即计数（计数数缓存键）和刷新（从缓存中删除所有数据）。双方可以解决，如果我能在高速缓存中循环的关键。

But there are two features of EntLib I find difficult to convert. Namely "Count" (counting number of keys in cache) and "Flush" (removing all data from cache). Both could be solved if I could iterate the keys in cache.

有一个名为 ClearRegion（串区域）的方法，但这需要我就全部搞定/认沽/添加的方法我用指定的区域名称，这将需要一些手动容易出错的工作。

There is a method called ClearRegion(string region), but that required me to specify a region name on all Get/Put/Add-methods I use, which would require some manual error-prone work.

有没有办法让在高速缓存中的密钥列表？ 有没有我可以使用默认的区域名称？ 我怎样才能刷新缓存的时候我没有用一个区域名称？

Is there any way to get a list of keys in cache? Is there a default region name I can use? How can I flush the cache when I haven't used a region name?

推荐答案

请参阅my为previous答案我的炒作的作为缓存的内部工作原理，当你不指定区域，以及如何可以得到不在一个对象的个数命名的区域。

See my previous answer for my speculation as to how the cache works internally when you don't specify a region, and how you can get the count of objects that aren't in a named region.

我们可以使用相同的技术建立一个Flush方法：

We can build a Flush method using the same technique:

public void Flush (this DataCache cache) { foreach (string regionName in cache.GetSystemRegions()) { cache.ClearRegion(regionName) } }

正如我说有，我想叫区域是的可能的要走的路 - 这在我看来，使用它们解决更多的问题比它创建

As I said there, I think named regions are probably the way to go - it seems to me that using them solves more problems than it creates.
