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(Of Object), _ state As Object, _ creationOptions As TaskCreationOptions _ ) As Task

C#
public Task StartNew( Action<Object> action, Object state, TaskCreationOptions creationOptions )

Parameters

action: Type: System..::.Action<(Of <(Object>)>)
The action delegate to execute asynchronously.

state: Type: System..::.Object
An object containing data to be used by the action delegate.

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

Exception	Condition
System..::.ArgumentNullException	The exception that is thrown when the action argument is null.
System..::.ArgumentOutOfRangeException	The exception that is thrown when the creationOptions argument specifies an invalid TaskCreationOptions value.
