Creates a continuation that executes when the target task completes according to the specified TaskContinuationOptions.

Namespace:  System.Threading.Tasks
Assemblies:   System.Threading.Tasks (in System.Threading.Tasks.dll)
  mscorlib (in mscorlib.dll)

public:
Task^ ContinueWith(
	Action<Task^>^ continuationAction, 
	TaskContinuationOptions continuationOptions
)

Parameters

continuationAction
Type: System::Action<Task>

An action to run according to the specified continuationOptions. When run, the delegate will be passed the completed task as an argument.

continuationOptions
Type: System.Threading.Tasks::TaskContinuationOptions

Options for when the continuation is scheduled and how it behaves. This includes criteria, such as OnlyOnCanceled, as well as execution options, such as ExecuteSynchronously.

Return Value

Type: System.Threading.Tasks::Task
A new continuation Task.

ExceptionCondition
ArgumentNullException

The continuationAction argument is null.

ArgumentOutOfRangeException

The continuationOptions argument specifies an invalid value for TaskContinuationOptions.

The returned Task will not be scheduled for execution until the current task has completed. If the continuation criteria specified through the continuationOptions parameter are not met, the continuation task will be canceled instead of scheduled.

The following example demonstrates using TaskContinuationOptions to specify that a continuation task should run synchronously when the antecedent task completes. (If the specified task has already completed by the time ContinueWith is called, the synchronous continuation will run on the thread calling ContinueWith.)
