| TaskFactory..::.StartNew Method (Action, CancellationToken) |
| TaskFactory Class See Also Send Feedback |
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, _ cancellationToken As CancellationToken _ ) As Task |
| C# |
|---|
public Task StartNew( Action action, CancellationToken cancellationToken ) |
Parameters
- action
- Type: System..::.Action
The action delegate to execute asynchronously.
- cancellationToken
- Type: System.Threading..::.CancellationToken
The CancellationToken that will be assigned to the new 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..::.ObjectDisposedException | The provided CancellationToken has already been disposed. |
