c# - 任务 T.IsCancelled = false;我怎样才能做到这一点？

Question

我有这个异步方法:

private static async Task Initializ( ) { /*Do Stuff Here*/ }

我希望能够监控调用此函数所产生的任务:

Task T = Class.Initialize( );
if (T.IsCancelled){ /*Do Stuff Here*/ }

我有一个 CancellationTokenSource。

我怎样才能使 T(或函数 Initialize)利用该源 token ，这样如果它被取消，T.IsCancelled 将是真的吗？

编辑

我不确定，但我认为我的问题的答案在于使用 TaskCompletionSource 对象。 Mike 给出的答案让我得出了这个结论......

Answer 1

来自 the documentation

A Task will complete in the TaskStatus.Canceled state under any of the following conditions:

• Its CancellationToken was marked for cancellation before the task started executing,

• The task acknowledged the cancellation request on its already signaled CancellationToken by throwing an OperationCanceledException that bears the same CancellationToken.

• The task acknowledged the cancellation request on its already signaled CancellationToken by calling the ThrowIfCancellationRequested method on the CancellationToken.
