StartNew Method (Action, TaskCreationOptions)

Task Parallel System.Threading

Creates and starts a Task.

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

Syntax

Visual Basic (Declaration)
Public Function StartNew ( _
	action As Action, _
	creationOptions As TaskCreationOptions _
) As Task
C#
public Task StartNew(
	Action action,
	TaskCreationOptions creationOptions
)

Parameters

action
Type: System..::.Action
The action delegate to execute asynchronously.
creationOptions
Type: System.Threading.Tasks..::.TaskCreationOptions
A TaskCreationOptions value that controls the behavior of the created Task.

Return Value

The started Task.

Remarks

Calling StartNew is functionally equivalent to creating a Task using one of its constructors and then calling Start to schedule it for execution. However, unless creation and scheduling must be separated, StartNew is the recommended approach for both simplicity and performance.

Exceptions

ExceptionCondition
System..::.ArgumentNullExceptionThe exception that is thrown when the action argument is null.
System..::.ArgumentOutOfRangeExceptionThe exception that is thrown when the creationOptions argument specifies an invalid TaskCreationOptions value.
