Task<TResult> Constructor (Func<TResult>)

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

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

public Task(
	Func<TResult> function
)

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.

ExceptionCondition
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 Task.Run<TResult>(Func<TResult>) and TaskFactory<TResult>.StartNew(Func<TResult>) methods.
