MouseOver trigger doesn't work in code behind?

I am trying to create a MouseOver style in the code behind. I have done this succesfully in XAML, but I need to do it in C#. Here is my style code:

Style style = new Style();

style.Setters.Add(new Setter(Button.BackgroundProperty, new BrushConverter().ConvertFrom("#FF0000") as Brush));

Trigger mouseOver = new Trigger() {
    Property = IsMouseOverProperty,
    Value = true,
};

mouseOver.Setters.Add(new Setter(Button.BackgroundProperty, new BrushConverter().ConvertFrom("#00FF00") as Brush));
style.Triggers.Add(mouseOver);

The buttons apply the style in the XAML code. I can see them change color when this code is run, but the MouseOver never changes. I've looked at dozens of MSDN articles and Stackoverflow posts about this but none of the solutions worked in my case.

What am I doing wrong here?

Suppose the x:Name of the button is equal to "Button1"

You need to add at the end:

<Button x:Name="Button1"/>

Style style = new Style();

style.Setters.Add(new Setter(Button.BackgroundProperty, new 
BrushConverter().ConvertFrom("#FF0000") as Brush));

Trigger mouseOver = new Trigger() {
Property = IsMouseOverProperty,
Value = true,
};

mouseOver.Setters.Add(new Setter(Button.BackgroundProperty, new 
BrushConverter().ConvertFrom("#00FF00") as Brush));
style.Triggers.Add(mouseOver);

Button1.Style = style;
