c# - 打破 parallel.foreach？

Question

我如何突破 parallel.for循环？

我有一个非常复杂的语句，如下所示:

Parallel.ForEach<ColorIndexHolder>(ColorIndex.AsEnumerable(),
    new Action<ColorIndexHolder>((ColorIndexHolder Element) =>
    {
        if (Element.StartIndex <= I && Element.StartIndex + Element.Length >= I)
        {
            Found = true;
            break;
        }
    }));

使用并行类，我可以优化这个过程。然而;我不知道如何打破并行循环？ break; 语句抛出以下语法错误:

No enclosing loops out of which to break or continue

使用 ParallelLoopState.Break方法:

 Parallel.ForEach(list,
    (i, state) =>
    {
       state.Break();
    });

或者在你的情况下:

Parallel.ForEach<ColorIndexHolder>(ColorIndex.AsEnumerable(),
    new Action<ColorIndexHolder, ParallelLoopState>((ColorIndexHolder Element, ParallelLoopState state) =>
    {
        if (Element.StartIndex <= I && Element.StartIndex + Element.Length >= I)
        {
            Found = true;
            state.Break();
        }
    }));
