| 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, _ 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.

| 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. |
