✅ Calling a nullable Action or Func

Hugh · 2022-12-27T20:25:58.251Z

In my class I have the following: ```cs private Action ? _myAction; ``` Is there a way of calling it if it isn't null in a single line? Something like (and this doesn't work): ```cs _myAction?(true); ``` Similarly with a Func, can I do something like: ```cs private Func ? _myFunc; bool result = _myFunc?(true) ?? false; ```

In my class I have the following:

private Action<bool>? _myAction;

private Action<bool>? _myAction;

private Action<bool>? _myAction;

private Action<bool>? _myAction;

Is there a way of calling it if it isn't null in a single line? Something like (and this doesn't work):

_myAction?(true);

_myAction?(true);

_myAction?(true);

_myAction?(true);

Similarly with a Func, can I do something like:

private Func<bool, bool>? _myFunc;

bool result = _myFunc?(true) ?? false;

private Func<bool, bool>? _myFunc;

bool result = _myFunc?(true) ?? false;

private Func<bool, bool>? _myFunc;

bool result = _myFunc?(true) ?? false;

private Func<bool, bool>? _myFunc;

bool result = _myFunc?(true) ?? false;
