.net Cache缓存的使用
作者:互联网
前段时间项目中要用到缓存已解决效率的问题,研究了一下.net中的Cache缓存,结果是研究了半天最后还是没有用这种方式,哎,很多问题从业务上就能优化,不说了
using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Web; using System.Web.Caching; namespace Erp.Ship.Tool { public class CacheHelper { /// <summary> /// 获取数据缓存 /// </summary> /// <param name="cacheKey">键</param> public static object GetCache(string cacheKey) { var objCache = HttpRuntime.Cache.Get(cacheKey); return objCache; } /// <summary> /// 设置数据缓存 /// </summary> public static void SetCache(string cacheKey, object objObject) { var objCache = HttpRuntime.Cache; objCache.Insert(cacheKey, objObject); } /// <summary> /// 设置数据缓存 /// </summary> public static void SetCache(string cacheKey, object objObject, int timeout = 7200) { try { if (objObject == null) return; var objCache = HttpRuntime.Cache; //相对过期 //objCache.Insert(cacheKey, objObject, null, DateTime.MaxValue, timeout, CacheItemPriority.NotRemovable, null); //绝对过期时间 objCache.Insert(cacheKey, objObject, null, DateTime.Now.AddSeconds(timeout), TimeSpan.Zero, CacheItemPriority.High, null); } catch (Exception) { //throw; } } /// <summary> /// 移除指定数据缓存 /// </summary> public static void RemoveAllCache(string cacheKey) { var cache = HttpRuntime.Cache; cache.Remove(cacheKey); } /// <summary> /// 移除全部缓存 /// </summary> public static void RemoveAllCache() { var cache = HttpRuntime.Cache; var cacheEnum = cache.GetEnumerator(); while (cacheEnum.MoveNext()) { cache.Remove(cacheEnum.Key.ToString()); } } } }View Code
其实一提到缓存我就想到了redis缓存,所以特意了解了一下,这两者的区别,redis属于是分布式缓存,Cache只能是单体的,平常的业务管理系统,Cache够用了,redis肯定是功能更加强大的,我了解的也不多
