public Task StartNew( Action<Object> action, Object state, CancellationToken cancellationToken ) |
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.
- 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.
