c# - 有什么办法可以在 c# 中制作某种 "aggregated"CancellationTokenSource 吗？

Question

有没有什么方法可以实现 CancellationTokenSource，允许在里面聚合两个或多个其他 CancellationToken？这让我可以写这样的东西:

void async Task DoSomeWorkAsync(CancelationToken Token)
{
    var cts = AggregatedCancelationTokenSource(Token, 
      new CancelationTokenSource(TimeSpan.FromSeconds(30)).Token);
    //Cancelation occurred:
    // when timeout will be expired 
    //  or 
    // when external Token.IsCancellationRequested will start to return "true"
    await DoSomeOtherWorkAsync(cts.Token);
}

是的，您可以使用 CancellationTokenSource.CreateLinkedTokenSource，来自 documentation :

Creates a CancellationTokenSource that will be in the canceled state when any of the source tokens are in the canceled state.
