将颜色名称转换为SolidColorBrush

Question

How I can cast color name to SolidColorBrush type? I mean the word ie "Yellow".

SolidColorBrush scb =  ??? ; // "Yellow" 

Thank you!

Answer 1

For getting the color, use:

Color col=(Color)ColorConverter.ConvertFromString("Red"); 

Then create your brush:

Brush brush=new SolidColorBrush(col);

or if you can use the Colors-enum

Brush brush=new SolidColorBrush(Colors.Red);

Answer 2

If you already know the name of the color you can get the brush directly from Brushes :

SolidColorBrush scb = Brushes.Yellow; //scb seems a bit redundant at this point...

In code you should usually not use converters unless you have a string whose value you do not know.

Answer 3

You cannot cast one to another. They are simply different concepts. A brush is brush and color is, well, a color. Just because a brush "paints" in a specific color, doesn't mean you can interchange one with another.

You can however create a SolidColorBrush with a specific color, for example:

 var brush = new SolidColorBrush(Color.Yellow);

Answer 4

// Yellow is green + red
SolidColorBrush yellowBrush = new SolidColorBrush(System.Windows.Media.Color.FromRgb(255, 255, 0));
