asp.net(vs2005) + Sql2000 缓存依赖

1.开启数据库缓存依赖支持

开始,运行,cmd 输入 C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\aspnet_regsql -S localhost -E -d database -ed

database 为数据库名

2. web.config中添加:

<caching>
      <sqlCacheDependency enabled="true">
        <databases>
          <add name="cachename" connectionStringName="SqlConnection" pollTime="12000"/>
        </databases>
      </sqlCacheDependency>
    </caching>

3.要缓存的数据页:

using System.Web.Caching; //引用命名空间

private DataSet list; //缓存这个dataset;

Page_Load中:

SqlCacheDependencyAdmin.EnableTableForNotifications(ConfigurationManager.ConnectionStrings["SqlConnection"].ConnectionString, "Tablename");
SqlCacheDependency cacheinfo = new SqlCacheDependency("cachename", "Tablename");

*Tablename 要缓存的表名

list = (DataSet)Cache["is"];
        if (list == null)
        {
            list = shop.SelindexNew(); // 这个为业务逻辑层方法,也就是读取数据的代码,方法返回dataset

Cache.Insert("is", list, cacheinfo);
        }
