从外面打破平行ForEach

Question

谷歌没有帮助我,所以也没有.

var timer = new System.Timers.Timer(5000);
timer.Elapsed += BreakEvent;
timer.Enabled = true;

Parallel.ForEach<string>(fileNames, (fileName, state) =>
{
    try
    {
        ProcessFile(fileName);
    }
    catch (Exception)
    {

    }
    finally
    {

    }
});

我想ForEach在5秒(in BreakEvent)之后打破这个循环.

当然它可以是一个按钮或任何东西.

我知道破坏(在我的例子中)

state.Stop();

但它仍然在循环中.

它甚至可能吗？

编辑:

对于那些搜索到其他方式的人来说,我就是这样的:

var timer = new System.Timers.Timer(5000);

timer.Elapsed += new System.Timers.ElapsedEventHandler((obj, args) =>
{
    state.Stop();
});

timer.Enabled = true;

我建议使用取消:

// Cancel after 5 seconds (5000 ms)
using (var cts = new CancellationTokenSource(5000))
{
    var po = new ParallelOptions()
    {
        CancellationToken = cts.Token,
    };

    try
    {
        Parallel.ForEach(fileNames, po, (fileName) =>
        {
            //TODO: put relevant code here
        });
    }
    catch (OperationCanceledException e)
    {
        //TODO: Cancelled 
    }
}
