C# event += delegate {} equivalent in VB.NET

Question

Well, I was translating a C# into VB.NET using developer fusion, and the API didn't translated me that part...

owner.IsVisibleChanged += delegate
            {
                if (owner.IsVisible)
                {
                    Owner = owner;
                    Show();
                }
            };

I know that += is for AddHandler owner.IsVisibleChanged, AdressOf (delegate??), so, which is the equivalent for that part?

Thanks in advance.

PD: I don't enough money for buy .NET Reflector :( And I wasted the trial.

There are free decompilers also. [Jetbrains DotPeek](http://www.jetbrains.com/decompiler/) and [ILSpy](http://ilspy.net/) for example.. — Soner Gönül, Apr 26 '14 at 11:02
Wait, are you translating code into C# (like your question says), or into VB.NET (like your question title says)? — , Apr 26 '14 at 11:10
Then please see [this other question](http://stackoverflow.com/q/10178159/743382). Despite the fact that the answer there is not accepted, I believe it is correct and also answers your question. — , Apr 26 '14 at 11:17

There are two parts here.

Anonymous methods. delegate in C# roughly corresponds to an anonymous Sub in VB here.
Adding event handlers. += in C#, AddHandler in VB.

Putting it together:

AddHandler owner.IsVisibleChanged, _
    Sub()
        …
    End Sub

Incidentally, the AddressOf operator you’ve mentioned is used in VB to refer to a (non-anonymous) method without calling it. So you would use it here if you would refer to an existing, named method rather than an anonymous method.

Thanks! You was quickly! :D – z3nth10n Apr 26 '14 at 11:39 — z3nth10n, Apr 26 '14 at 11:39
