The execute argument must not be null.

public AsyncDelegateCommand ( Func execute ) : System.Threading.Tasks
execute	Func	Async Delegate to execute when Execute is called on the command.
Результат	System.Threading.Tasks

AsyncDelegateCommand() публичный Метод

Initializes a new instance of the AsyncDelegateCommand class.

The execute argument must not be null.

public AsyncDelegateCommand ( Func execute, Func canExecute ) : System.Threading.Tasks
execute	Func	Async Delegate to execute when Execute is called on the command.
canExecute	Func	Delegate to execute when CanExecute is called on the command.
Результат	System.Threading.Tasks

AsyncDelegateCommand() публичный Метод

protected OnCanExecuteChanged ( EventArgs e ) : void
e	EventArgs	The instance containing the event data.
Результат	void

RaiseCanExecuteChanged() публичный Метод

Raises the CanExecuteChanged event.

public RaiseCanExecuteChanged ( ) : void
Результат	void
