关于HttpRuntime.Cache的运用

Posted 2020-09-12 小酒

存Cache方法：

HttpRuntime.Cache.Add( KeyName,//缓存名 KeyValue,//要缓存的对象 Dependencies,//依赖项 AbsoluteExpiration,//绝对过期时间 SlidingExpiration,//相对过期时间 Priority,//优先级 CacheItemRemovedCallback);//缓存过期引发事件

示例：

HttpRuntime.Cache.Add("CurrencyFundCodeCache", docs, null, DateTime.Now.AddMinutes(2),  Cache.NoSlidingExpiration, CacheItemPriority.Normal, null);

鄙人自己写了一个示例

class Program
    {
        static void Main(string[] args)
        {
            if (HttpRuntime.Cache["arrKey"] != null)
            {
                MyClass myClass = HttpRuntime.Cache["myClass"] as MyClass;
            }
            else
            {
                MyClass myClass = new MyClass { ID = 1, Name = "张三", six = "男" };
                HttpRuntime.Cache.Add("myClass", myClass, null, DateTime.Now.AddDays(3), Cache.NoSlidingExpiration, CacheItemPriority.Normal, null);
            }

            Console.ReadKey();
              
            Console.ReadKey();
        }
public class MyClass
    {
        public int ID { get; set; }
        public string Name { get; set; }
        public string six { get; set; }
    }
