TaskFactory.StartNew Method (Action, TaskCreationOptions)

July 28, 2014

Creates and starts a Task.

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

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

Type: System.Threading.Tasks.Task
The started Task.

ExceptionCondition
ArgumentNullException

The exception that is thrown when the action argument is null.

ArgumentOutOfRangeException

The exception that is thrown when the creationOptions argument specifies an invalid TaskCreationOptions value.

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.
