c# – PLINQ异常

static void Main(string[] args)
    {
        var lt = new List<int>() {1,2,3,4,5};
        try
        {
            var nlt = lt.AsParallel().Select(Test).ToList();
        }
        catch (AggregateException e)
        {
            foreach (var ex in e.InnerExceptions)
            {
                Console.WriteLine(ex.Message);
            }
        }

    }

    private static bool Test(int n)
    {
        if (n == 1)
        {
            Thread.Sleep(1000);
        }
        if (n == 3)
        {
            Thread.Sleep(3000);
        }
        if (n == 5)
        {
            Thread.Sleep(5000);
        }
        if (n == 2 || n == 4)
        {
            throw new Exception("New exception");
        }
        Console.WriteLine("element : {0}",n);
        return true;
    }

结果是在5s之后总是抛出aggregateException(直到最后一个线程完成).似乎如果某些线程抛出异常,该线程的其余部分仍将继续运行.完成最后一个线程后,框架会聚合所有异常并将它们包装在aggregateException中.

是框架行为,如果10个线程中有3个抛出异常,它将等待其余7个线程完成并在最后抛出aggreagteException.

但是,当我遇到这个文件时：
https://msdn.microsoft.com/en-us/library/dd460712(v=vs.110).aspx

the query cannot continue after the exception is thrown. By the time your application code catches the exception,PLINQ has already stopped the query on all threads.

我想知道为什么我的代码不会以这种方式运行？如果在抛出异常后查询无法继续,则不会永远不会打印元素1,5,因为异常将已经抛出.
