ASP.NET缓存处理类实例
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:
Justcopythiscodeintoanewclassfile(.cs)andaddittoyourASP.NETwebsite.OnethingtokeepinmindisthatdatastoredinASP.NETCachecanbeaccessibleacrossallsessions.SowhencreatingacacheIDfortheobjecttobestored,itmustbeunique(oritcouldbeoverwritten).IusuallystoretheuniquecacheIDinthesessionandthenusethattoreferrencethecacheID.(e.g.CacheHandler.Write(Session["MyCacheData"],myData);)
具体代码如下:
usingSystem;
usingSystem.Collections.Generic;
usingSystem.Web.Caching;
usingSystem.Web;
///<summary>

publicclassCacheHandler
{
publicstaticboolWrite(stringcacheID,objectdata)
{
if(HttpContext.Current==null)
returnfalse;
if(cacheID==null||cacheID.Equals(""))
returnfalse;
HttpRuntime.Cache.Insert(
cacheID,data,null,Cache.NoAbsoluteExpiration,
Cache.NoSlidingExpiration,CacheItemPriority.NotRemovable,null
);
returntrue;
}
publicstaticobjectRead(stringcacheID)
{
if(HttpContext.Current==null)
returnnull;
returnHttpRuntime.Cache.Get(cacheID);
}
publicstaticvoidRemove(stringcacheID)
{
if(HttpContext.Current==null)
return;
if(cacheID==null||cacheID.Equals(""))
return;
HttpRuntime.Cache.Remove(cacheID);
}
}
希望本文所述对大家的asp.net程序设计有所帮助。
