WPF color assignment?

Question

WPF

There is a Border element whose color needs to be changed. How to give it the value #FF3399FF ? (not in XAML)
There is a second way: create the color yourself in the constructor, but then how to assign it in the code?

There is a second way: create the color yourself in the constructor, but then how to assign it in the code?

Border has a Background property. This is a property of type Brush. You create a property of type Brush in the class, bind to it in XAML, and define this property in the constructor as you like. XAML
example :

...
   <Border Background={Binding BorderBrush} />
...

behavior:

class MyControl
{
   public MyControl()
   {
       BorderBrush = new SolidColorBrush(youColor);//youColor - создаете свой цвет классом Color.
   }
   public Brush BorderBrush {get; private set;}
}

try like this
