.net - What does "{x:Static}" mean in XAML?

Question

What does {x:Static} mean in XAML?

Code sample:

<SolidColorBrush Color="{x:Static SystemColors.ControlColor}" />

Answer 1

It is a way to insert any static value into XAML. For example, if I have a class:

namespace A 
{ 
    public class MyConstants 
    {
        public static readonly string SomeConstantString = "BAM!";
    }
}

I can place it into a WPF UI using XAML like this:

<TextBlock Text="{x:Static A:MyConstants.SomeConstantString}" />

Notice, you will have to import the namespace in which MyConstants is defined into your XAML. So in the or element do something like:

xmlns:A="clr-namespace:A"
