Question

I was looking around for an answer to this but couldn’t find anything related. I have learnt to use Action.Invoke() when using an Action, but do you actually need to use .Invoke?

Say I have this Action:

Action<int> action = x =>
{
    Console.WriteLine(x + 1);
};

Do I use:

action.Invoke(2);

or

action(2);

What’s the difference?

Thanks

Answer 1

Its the same thing, action(2); basically calls action.Invoke(2);
The compiler converts action(2) into action.Invoke(2);

From a post from Jon Skeet:

Personally I typically use the shortcut form, but just occasionally it
ends up being more readable to explicitly call Invoke. For example,
you might have:

if (callAsync)
{
    var result = foo.BeginInvoke(...);
    // ...
}
else
{
    foo.Invoke(...);
    // ...
}
