Task Constructor (Action(Of Object), Object, CancellationToken)

 

Initializes a new Task with the specified action, state, and options.

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

Public Sub New (
	action As Action(Of Object),
	state As Object,
	cancellationToken As CancellationToken
)

Parameters

action
Type: System.Action(Of Object)

The delegate that represents the code to execute in the task.

state
Type: System.Object

An object representing data to be used by the action.

cancellationToken
Type: System.Threading.CancellationToken

The CancellationToken that that the new task will observe.

Exception Condition
ObjectDisposedException

The CancellationTokenSource that created cancellationToken has already been disposed.

ArgumentNullException

The action argument is null.

Rather than calling this constructor, the most common way to instantiate a Task object and launch a task is by calling the static TaskFactory.StartNew(Action(Of Object), Object, CancellationToken) method. The only advantage offered by this constructor is that it allows object instantiation to be separated from task invocation.
