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:
using System; using System.Collections.Generic; using System.Web.Caching; using System.Web; /// <summary> /// This class reads/writes to ASP .NET server cache. 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. This class was created as an alternative to /// storing large objects in the session. /// </summary> public class CacheHandler { public static bool Write(string cacheID, object data) { if (HttpContext.Current == null) return false; if (cacheID == null || cacheID.Equals("")) return false; HttpRuntime.Cache.Insert( cacheID, data, null, Cache.NoAbsoluteExpiration, Cache.NoSlidingExpiration, CacheItemPriority.NotRemovable, null ); return true; } public static object Read(string cacheID) { if (HttpContext.Current == null) return null; return HttpRuntime.Cache.Get(cacheID); } public static void Remove(string cacheID) { if (HttpContext.Current == null ) return; if (cacheID == null || cacheID.Equals("")) return; HttpRuntime.Cache.Remove(cacheID); } }
以上就是ASP.NET中怎么实现一个缓存处理类,小编相信有部分知识点可能是我们日常工作会见到或用到的。希望你能通过这篇文章学到更多知识。更多详情敬请关注亿速云行业资讯频道。
