How to add event handler programmatically in WPF like one can do in Winform

Question

What's the equivalent of this winform instruction:

this.button1.Click += new System.EventHandler(this.button1_Click); 

in WPF ?

Update: also for a slider. And what namespace should I declare ?

My point is NOT to use XAML.

Answer 1

Something like this...

this.btnTest.Click+=new RoutedEventHandler(btnTest_Click);
