StartNew Method (Func(Object, TResult), Object)

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

 

Creates and starts a task.

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

public Task<TResult> StartNew(
	Func<object, TResult> function,
	object state
)

Parameters

function
Type: System.Func<Object, TResult>

A function delegate that returns the future result to be available through the task.

state
Type: System.Object

An object that contains data to be used by the function delegate.

Return Value

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

The started task.

Exception Condition
ArgumentNullException

The function argument is null.

Calling StartNew is functionally equivalent to creating a task by using one of the Task<TResult> constructors and then calling the Start method to schedule it for execution.

However, unless creation and scheduling must be separated, StartNew is the recommended approach for both simplicity and performance.
