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.

Accepted Answer

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.
