是否将任务创建为后台线程？ [英] Are Tasks created as background threads?

问题描述

我只是想知道在dot.net 4中的新任务类是否正在创建一个后台或前台线程？

I'm just wondering whether the new Task class in dot.net 4 is creating a background or foreground thread ?

通常我会设置IsBackground

Normally I'd set "IsBackground" on a Thread, but there's no such attribute on a Task.

我在MSDN上找不到任何这方面的文档： - （

I've not been able to find any documentation of this on MSDN :-(

推荐答案

不应难以验证：

class Program
{
    static void Main()
    {
        Task
            .Factory
            .StartNew(() => Console.WriteLine(Thread.CurrentThread.IsBackground))
            .Wait();
    }
}

$ b b

而答案是...

And the answer is ...
