AsyncRelayCommand Class

A reusable command that encapsulates the implementation of ICommand with support for async/await. Enables instant creation of an ICommand without implementing the ICommand interface for each command. The individual Execute, ExecuteAsync and CanExecute members are supplied via delegates.

The AsyncRelayCommand type exposes the following members.

Constructors

	Name	Description
	AsyncRelayCommand(Action)	Creates a new parameterless command that can always execute (CanExecute always returns Copy true ).
	AsyncRelayCommand(ActionObject)	Creates a new command that can always execute (CanExecute always returns Copy true ).
	AsyncRelayCommand(FuncTask)	Initializes a new instance of the AsyncRelayCommand class
	AsyncRelayCommand(FuncObject, Task)	Creates a new command that can always execute (CanExecute always returns Copy true ).
	AsyncRelayCommand(Action, FuncBoolean)	Creates a new parameterless command.
	AsyncRelayCommand(ActionObject, PredicateObject)	Creates a new command.
	AsyncRelayCommand(FuncTask, FuncBoolean)	Creates a parameterless new asynchronous command.
	AsyncRelayCommand(FuncObject, Task, PredicateObject)	Creates a new asynchronous command.

Methods

	Name	Description
	CanExecute	Determines whether this AsyncRelayCommand can execute.
	CanExecute(Object)	Determines whether this AsyncRelayCommand can execute.
	Equals	Determines whether the specified object is equal to the current object. (Inherited from Object.)
	Execute	Executes the AsyncRelayCommand on the current command target.
	Execute(Object)	Executes the AsyncRelayCommand on the current command target.
	ExecuteAsync	Executes the AsyncRelayCommand on the current command target asynchronously.
	ExecuteAsync(Object)	Executes the AsyncRelayCommand on the current command target asynchronously.
	Finalize	Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
	GetHashCode	Serves as the default hash function. (Inherited from Object.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	ToString	Returns a string that represents the current object. (Inherited from Object.)
