I have a simple and I need to change colors of my buttons every second in that . I use this code btnBlue.Background = new SolidColorBrush(Windows.UI.Colors.Blue) But it doesn't contain my custom color that I have use in xaml like #FF30B3DD ! So what should I do ? can anybody help me ?

推荐答案

您可以使用Color.FromArgb()在代码中定义自定义颜色:

You can use Color.FromArgb() to define a custom color in code:

btnBlue.Background = new SolidColorBrush(Color.FromArgb(255, 48, 179, 221));

或者，您可以预先在XAML中将颜色定义为资源:

Alternatively, you can define the color in XAML in advance as a resource:

<Page.Resources>
    <SolidColorBrush x:Key="BlueColor" Color="#FF30B3DD" />
</Page.Resources>

然后您可以从代码中引用资源:

You can then reference the resource from the code:

btnBlue.Background = (SolidColorBrush)Resources["BlueColor"];
