HttpRuntime緩存幫助類CacheHelper

CacheHelper實現(xiàn)功能

1,插入緩存

2,獲取緩存對象

3,刪除緩存數(shù)據(jù)

源碼CacheHelper.cs


using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Web;
using System.Web.Caching;

namespace Helper

        //插入緩存
        // CacheHelper.Insert(key, list, 60);
        //獲取緩存數(shù)據(jù)
        // list =CacheHelper.GetCache<List<Info>>(key);
        //刪除緩存
        // CacheHelper.Delete(key);
