推荐答案

如果是WPF，则静态类 Brushes 中有一组颜色.

If it's WPF, there is a collection of colors in the static class Brushes.

TextBox.Background = Brushes.Red;

当然，您可以根据需要创建自己的画笔.

Of course, you can create your own brush if you want.

LinearGradientBrush myBrush = new LinearGradientBrush();
myBrush.GradientStops.Add(new GradientStop(Colors.Yellow, 0.0));
myBrush.GradientStops.Add(new GradientStop(Colors.Orange, 0.5));
myBrush.GradientStops.Add(new GradientStop(Colors.Red, 1.0));
TextBox.Background = myBrush;
