与超时列表/到期的能力 [英] List with timeout/expire ability

问题描述

我需要这样的功能：

AddToList(txtName, timeExpire);

它看起来像自我描述，该项目将自动过期，并从列表中删除。

It looks like self-descriptive, the item will automatically expire and removed from the list.

我无法想象如何做到这一点。谁能给我一个线索？

I couldn't imagine how to do that. Can anyone give me a clue?

推荐答案

您也可以尝试这样的事情。

you can also try something like this.

创建一个自定义类

 public class Custom
    {
        string item; //will hold the item
        Timer timer; //will hanlde the expiry
        List<Custom> refofMainList; //will be used to remove the item once it is expired

        public Custom(string yourItem, int milisec, List<Custom> refOfList)
        {
            refofMainList = refOfList;
            item = yourItem;
            timer = new Timer (milisec);
            timer.Elapsed += new ElapsedEventHandler(Elapsed_Event);
            timer.Start();
        }

        private void Elapsed_Event(object sender, ElapsedEventArgs e)
        {
            timer.Elapsed -= new ElapsedEventHandler(Elapsed_Event);
            refofMainList.Remove(this);

        }
    }

现在，您可以创建列表<定制> 并使用它。它的项目将被删除，一旦指定的时间已经结束了。

Now you can create List<Custom> and use it. It's items will be deleted once specified time is over.
