TaskFactory::StartNew Method (Action^, TaskCreationOptions)

.NET Framework (current version)

Creates and starts a Task.

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

Syntax

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.

Exceptions

Exception	Condition
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.

Remarks

Calling StartNew is functionally equivalent to creating a Task using one of its constructors and then calling Start to schedule it for execution.

Starting with the .NET Framework 4.5, you can use the Run method with an Action object as a quick way to call StartNew with default parameters. For more information and code examples, see Task.Run vs Task.Factory.StartNew in the Parallel Programming with .NET blog.
