运行多个异步任务，并等待他们全部完成 [英] Running multiple async tasks and waiting for them all to complete

问题描述

我需要在控制台应用程序运行多个异步任务，并等待他们都在进一步处理之前完成。

I need to run multiple async tasks in a console application, and wait for them all to complete before further processing.

有许多文章在那里，但我似乎得到更糊涂的我越读。我已阅读并理解任务库的基本原则，但我显然缺少一个环节的某个地方。

There's many articles out there, but I seem to get more confused the more I read. I've read and understand the basic principles of the Task library, but I'm clearly missing a link somewhere.

据我所知，这是可能的连锁任务，让他们又完成之后启动（这是pretty的大部分场景都是我读过的文章），但我想我所有的任务运行的同时，我想知道，一旦他们都完成了。

I understand that it's possible to chain tasks so that they start after another completes (which is pretty much the scenario for all the articles I've read), but I want all my Tasks running at the same time, and I want to know once they're all completed.

什么是最简单的实现了情景是这样？

What's the simplest implementation for a scenario like this?

推荐答案

您可以创建许多任务，如：

you could create many tasks like:

List<Task> TaskList = new List<Task>();
foreach(...)
{
    var LastTask = new Task(SomeFunction);
    LastTask.Start();
    TaskList.Add(LastTask);
}

Task.WaitAll(TaskList.ToArray());
