Task Constructor (Action<Object>, Object, CancellationToken)

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

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

public:
Task(
	Action<Object^>^ action, 
	Object^ state, 
	CancellationToken cancellationToken
)

Parameters

action
Type: System::Action<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.

ExceptionCondition
ObjectDisposedException
