TaskFactory<TResult>.StartNew Method (Func<Object, TResult>, Object, TaskCreationOptions)

Creates and starts a Task<TResult>.

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

public Task<TResult> StartNew(
	Func<Object, TResult> function,
	Object state,
	TaskCreationOptions creationOptions
)

Parameters

function
Type: System.Func<Object, TResult>
A function delegate that returns the future result to be available through the Task<TResult>.
state
Type: System.Object
An object containing data to be used by the function delegate.
creationOptions
Type: System.Threading.Tasks.TaskCreationOptions
A TaskCreationOptions value that controls the behavior of the created Task<TResult>.

Return Value

Type: System.Threading.Tasks.Task<TResult>
The started Task<TResult>.

ExceptionCondition
ArgumentNullException

The exception that is thrown when the function 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<TResult> 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.
