Method CreateParametricAsyncDelegateCommand

CreateParametricAsyncDelegateCommand<T>(Func<T, CancellationToken, Task>, Func<T, bool>?, bool, bool, bool)

Creates an asynchronous command that accepts a parameter, with configurable cancellation support.

Declaration

public static AsyncDelegateCommand<T> CreateParametricAsyncDelegateCommand<T>(Func<T, CancellationToken, Task> execute, Func<T, bool>? canExecute, bool supportsCancellation, bool supportsConcurrentExecution, bool runsInBackground)

Parameters

Type	Name	Description
Func<T, CancellationToken, Task>	execute	The async delegate to invoke when the command is executed. Receives the parameter and a CancellationToken.
Func<T, bool>	canExecute	An optional delegate that determines whether the command can execute for a given parameter. If `null`, the command can always execute.
bool	supportsCancellation	If `true`, enables cancellation support via CancellationToken.
bool	supportsConcurrentExecution	If `true`, allows multiple concurrent executions of the command.
bool	runsInBackground	If `true`, the execution is dispatched to a background thread via Run(Func<Task>, CancellationToken).

Returns

Type	Description
AsyncDelegateCommand<T>	A new AsyncDelegateCommand<T> instance.

Type Parameters

Name	Description
T	The type of the command parameter.

Parameters

Type	Name	Description
Func<T, Task>	execute	The async delegate to invoke when the command is executed.
Func<T, bool>	canExecute	An optional delegate that determines whether the command can execute for a given parameter. If `null`, the command can always execute.
bool	supportsCancellation	If `true`, enables cancellation support (though the delegate won't receive the token).
bool	supportsConcurrentExecution	If `true`, allows multiple concurrent executions of the command.
bool	runsInBackground	If `true`, the execution is dispatched to a background thread via Run(Func<Task>, CancellationToken).

Returns

Type	Description
AsyncDelegateCommand<T>	A new AsyncDelegateCommand<T> instance.

Type Parameters

Name	Description
T	The type of the command parameter.
