Trick in C# with lambda and event

Question

I'm trying to figure out if there is a way to accomplish something like this:

Button button = new Button() { OnClick += (sender, e) => MessageBox.Show("hello") };

But it doesn't want to work :D I want to create a control and to add one event to it at the same time. Is it possible?

No, object initializers don't allow you to attach event handlers, unfortunately.

The C# team is aware of this limitation - there was some hope that this would be in C# 6, but the feature was dropped. I hope it was dropped due to a lack of time rather than to really lose the feature - maybe we'll see it in C# 7.
