	成员名称	说明
	None	Default = "Continue on any, no task options, run asynchronously" Specifies that the default behavior should be used. Continuations, by default, are scheduled when the antecedent task completes, regardless of the task's final TaskStatus.
	PreferFairness	A hint to a TaskScheduler to schedule a task in as fair a manner as possible, meaning that tasks scheduled sooner are more likely to be run sooner, and tasks scheduled later are more likely to be run later.
	LongRunning	The task is a long-running, course-grained operation. It provides a hint to the TaskScheduler that oversubscription may be warranted.
	AttachedToParent	The task is attached to a parent in the task hierarchy. The parent task is not marked as completed until this child task is completed as well.
	DenyChildAttach	An InvalidOperationException is thrown if an attempt is made to attach a child task to the created task.
	LazyCancelation	In the case of continuation cancellation, prevents completion of the continuation until the antecedent has completed.
	NotOnRanToCompletion	The continuation task should not be scheduled if its antecedent ran to completion. This option is not valid for multi-task continuations.
	NotOnFaulted	The continuation task should not be scheduled if its antecedent threw an unhandled exception. This option is not valid for multi-task continuations.
	NotOnCanceled	The continuation task should not be scheduled if its antecedent was canceled. This option is not valid for multi-task continuations.
	OnlyOnFaulted	The continuation task should be scheduled only if its antecedent threw an unhandled exception. This option is not valid for multi-task continuations.
	OnlyOnRanToCompletion	The continuation task should be scheduled only if its antecedent ran to completion. This option is not valid for multi-task continuations.
	ExecuteSynchronously	The continuation task should be executed synchronously. With this option specified, the continuation is run on the same thread that causes the antecedent task to transition into its final state. If the antecedent is already complete when the continuation is created, the continuation is run on the thread creating the continuation. Only very short-running continuations should be executed synchronously.
	IndependentlyCanceled	The task can be canceled independently of any other task.
	NotCancelable	The continuation task cannot be canceled.
	Default	The same as NotOnFaulted.
