本文实例讲述了ASP.NET缓存处理类。分享给大家供大家参考。具体如下：

ASP.NET 缓存处理类。

用法：

Just copy this code into a new class file (.cs) and add it to your ASP .NET website. One thing to keep in mind is that data stored in ASP .NET Cache can be accessible across all sessions. So when creating a cacheID for the object to be stored, it must be unique (or it could be overwritten). I usually store the unique cacheID in the session and then use that to referrence the cacheID. (e.g. CacheHandler.Write(Session["MyCacheData"], myData);)

具体代码如下：

? 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 3

For the sake of /// simplicity, the class writes objects to cache with no expirateion. /// Use the Remove() function to programmatically remove objects stored /// from the server cache.

希望本文所述对大家的asp.net程序设计有所帮助。
