ASP.NET/C#:以特定间隔运行命令 [英] ASP.NET / C#: Run command at specific interval

问题描述

我有一个使用SinglarR和MVC5编码的拍卖网站.我在数据库中存储了一个针对每个竞标者的信用卡令牌.在拍卖结束时，需要向中标者的信用卡收费.

I have an auction site coded using SinglarR, and MVC5.I have a credit card token stored in my database for every single bidder. At the end of the auction, the winning bidder's credit card needs to be charged.

最有效的方法是什么?我考虑过要使用过滤器，但是，代码只会在访客下次到达时才运行，这在某些日子可能会很长一段时间.

What would be the most efficient way to accomplish this? I thought about using a filter, however, the code would only be ran the next time a visitor arrives, which might be a long period of time on some days

推荐答案

听起来像您需要预定任务.可以使用HttpModule完成.实施类似的东西:

Sounds like you need a scheduled task. It can be done with HttpModule. Implement something like:

public class CheckAuctionsScheduleModule : IHttpModule
{
    static Timer timer;
    long interval = 60000; //60 secs
    static object synclock = new object();
    public void Init(HttpApplication app)
    {
        if(timer==null) timer = new Timer(new TimerCallback(CheckAuctions), null, 0, interval);
    }

    private void CheckAuctions(object obj)
    {
        lock (synclock)
        {
           //implement here your logic
           //check completed auctions
           //send notifications to bidder etc.  

        }
    }
    public void Dispose()
    { 
    //implement if needed
    }
}

在您的web.config中:

In your web.config:

<system.webServer>
  <modules>
    <add name="CheckAuctionsSchedule" type="MyMvcApp.Modules.CheckAuctionsScheduleModule"/>
  </modules>
</system.webServer>

注意:只要MVC应用程序正在运行，模块就可以工作.还有其他计划任务的解决方案(如Microsoft建议的Win服务).这很有用.

Note: Module works as long as MVC application running. There are other solutions for scheduled tasks(as microsoft recommends win services). This can be useful.
