Adding of EventHandler fails to convert properly C#->VB

[Emanuel Varga]

Hello,

I was wondering what would be the downside of converting c# event assignments:

radButton1.Click += radButton1_Click;

to:

AddHandler radButton1.Click, AddressOf radButton1_click

But from VB to C# it is working just fine.... why?

Lately I've started to use the converter a lot, in order to provide solutions to people in both C# and vb, and because of the fact that the forum does not allow for uploading files I'm creating all the code in the examples by hand.

It's always a pain having to convert all of the event handlers by hand....

Best Regards,

This is actually a limit of the underlying NRefactory engine that powers the Code Converter. I suggest you request this support on the SharpDevelop forums: http://community.sharpdevelop.net/tags/nrefactory/default.aspx. You can further test the NRefactory engine using the simple converter provided by the core team: http://codeconverter.sharpdevelop.net/SnippetConverter.aspx.

I'm not entirely sure why the core engine can convert in one direction and not other. If I had to guess, I would say the language shortcut in C# is too ambiguous. That is, "+=" can be used for a number of things in C#, such as concatenating strings or incrementing values, so it's not "guaranteed" to be an event handler. In VB, though, the explicit AddHandler can more reliably be converted.

Hopefully a solution will be available soon to save you the manual steps! Sorry for the trouble.
