仅在父事务完成时执行代码

Question

以下代码将输出:

Event published
Command executed

使用系统。我如何让EventPublisher在父事务中登记，这样它只在CommandHandler完成时执行。因此输出将是:

Command executed
Event published

代码:

class Program
    {
        static void Main(string[] args)
        {           
            var handler = new CommandHandler();
            handler.Execute();
            Console.ReadLine();
        }
    }
    public class CommandHandler
    {
        public void Execute()
        {
            var foo = new Foo();
            foo.DoSomething();
            Console.WriteLine("Command executed");
        }
    }
    public class EventPublisher
    {
        public void PublishEvent()
        {
            Console.WriteLine("Event published");
        }
    }
public class Foo
{
    public void DoSomething()
    {
        new EventPublisher().PublishEvent();
    }
}

Answer 1

我认为您需要的是跨所有代码的事务之外的异步代码执行

Answer 2

解决方案实际上是通过实现IEnlistmentNotification在事务中登记。
