问题描述

我有对象 obj，它是 3rd 方组件，

I have object obj which is 3rd party component,

// this could take more than 30 seconds
int result = obj.PerformInitTransaction();

我不知道里面发生了什么.我所知道的是，如果需要更长的时间，它就会失败.

I don't know what is happening inside.What I know is if it take longer time, it is failed.

如何为这个操作设置一个超时机制，这样如果超过30秒我就抛出MoreThan30SecondsException?

how to setup a timeout mechanism to this operation, so that if it takes more than 30 seconds I just throw MoreThan30SecondsException ?

推荐答案

您可以在单独的线程中运行该操作，然后在线程加入操作上设置超时:

You could run the operation in a separate thread and then put a timeout on the thread join operation:

using System.Threading;

class Program {
    static void DoSomething() {
        try {
            // your call here...
            obj.PerformInitTransaction();
        } catch (ThreadAbortException) {
            // cleanup code, if needed...
        }
    }

    public static void Main(params string[] args) {

        Thread t = new Thread(DoSomething);
        t.Start();
        if (!t.Join(TimeSpan.FromSeconds(30))) {
            t.Abort();
            throw new Exception("More than 30 secs.");
        }
    }
}
