MVC 使用缓存

public AController()
{
ViewBag["Class"] = GetClass();
} private List<BlogsClass> GetClass(int parentId)
{
List<BlogsClass> list;
//查询出分类 尼玛每次都得查,很烦! 有木有? 考虑缓存 if (HttpContext.Cache["Class"] == null)
{
IClass _Class = new CalssData();
list = _Class.GetParentClass(parentId);
HttpContext.Cache.Add("Class", list, new CacheDependency(HttpContext.Server.MapPath("~/web.config")), DateTime.Now.AddDays(), TimeSpan.Zero, CacheItemPriority.High, null);
HttpContext.Cache["Class"] = list;
}
else
{
list = HttpContext.Cache["Class"] as List<BlogsClass>;
}
return list;
}

结果。。。
