How do I access a resource(style) through code? - wpf

Question

I have a Resource Dictionary containing all my custom styles for the programs controls.
The Dictionary is mergerd with the application's resources as displayed below:
<ResourceDictionary x:Key="Controls">
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="Controls.xaml" />
</ResourceDictionary.MergedDictionaries>
</ResourceDictionary>
I can easily access the different styles through xaml:
<Button Style="{StaticResource Button}" />
But whenever I try assigning controls with this style through code, it fails.
I've tried:
Button.Style = Application.Current.Resources("Button")
Button.Style = CType(Application.Current.Resources("Button"), Style)
And different approaches similar to the ones above.
During testing some of the different ways to get the styles, I was faced with "Resource not found" but when using the above ones the program seemed to find the style.
I could successfully run the program - but without any visual proof that the style was indeed applied.
How do I properly assign a control a style found in a Resource Dictionary?

Answer 1

Use Application.Current.Resources["Button"].

Answer 2

For any descendants: here is how I succeded to apply a style from a resource to a dynamically created control through code. (Given that you have a Resource Dictionary containing the style)
First step: Include the Resource Dictionary
To make a Resource Dictionary easily accessible from code, add it through code.
VB
Dim myResourceDictionary As New ResourceDictionary
myResourceDictionary .Source = New _
Uri("/YourApplication;component/YourDictionary.xaml",
UriKind.RelativeOrAbsolute)
C#
var myResourceDictionary = new ResourceDictionary
{
Source = new Uri("/YourApplication;component/YourDictionary.xaml", UriKind.RelativeOrAbsolute)
};
Replace "YourApplication" with your solution name, and "YourDictionary" with your Resource Dictionary file.
Second step: Assign the Style
To make use of the newly imported Resource Dictionary, simply assign a control a style;
VB
Dim myButton As New Button
Dim myButtonStyle As Style = myResourceDictionary("YourStyleKey")
myButton.Style = myButtonStyle
C#
var myButtonStyle= myResourceDictionary["YourStyleKey"] as Style;
var myButton = new Button { Style = myButtonStyle };
Special thanks to user Stefan Denchev for giving me an article covering this.
As C# isn't my strong side, please edit this if I've made any mistake.
