Task(TResult) Constructor (Func(TResult), TaskCreationOptions)

Task<TResult> Constructor (Func<TResult>, TaskCreationOptions)

 

Initializes a new Task<TResult> with the specified function and creation options.

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

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

Parameters

function
Type: System.Func<TResult>

The delegate that represents the code to execute in the task. When the function has completed, the task's Result property will be set to return the result value of the function.

creationOptions
Type: System.Threading.Tasks.TaskCreationOptions

The TaskCreationOptions used to customize the task's behavior.

Exception Condition
ArgumentOutOfRangeException

The creationOptions argument specifies an invalid value for TaskCreationOptions.

ArgumentNullException

The function argument is null.

Rather than calling this constructor, the most common way to instantiate a Task<TResult> object and launch a task is by calling the static TaskFactory<TResult>.StartNew(Func<TResult>, TaskCreationOptions) method. The only advantage offered by this constructor is that it allows object instantiation to be separated from task invocation.
