c# – 如何访问当前主题颜色？

2023年3月20日 258次阅读

我有一个
Windows Phone 8应用程序,它在WebBrowser控件中呈现一些HTML(来自RSS / Atom提要).为了使这个HTML看起来更原生,我通过一个简单的动员器运行它,通过重写HTML结构和设置一些CSS使布局,字体,图像等看起来更原生.

这很好用.但是,我想确保动员者生成的CSS将用户当前主题的颜色应用于背景,文本,链接等.虽然我可以在XAML文档中应用主题颜色,但我还没有找到办法从C#中获取这些颜色.这可能吗？如果是这样,怎么样？

最佳答案 您可以获得如
here所示的强调色.

// Determine the accent color.
Color currentAccentColorHex = (Color)Application.Current.Resources["PhoneAccentColor"];

获取颜色名称不是最漂亮的方法,如果这是您想要的,但您可以使用与WP7和WP8兼容的颜色.

string currentAccentColor = "";

switch (currentAccentColorHex.ToString())
{
    case "#FF1BA1E2": currentAccentColor = "blue"; break;
    case "#FFA05000": currentAccentColor = "brown"; break;
    case "#FF339933": currentAccentColor = "green"; break;
    case "#FFE671B8": currentAccentColor = "pink"; break;
    case "#FFA200FF": currentAccentColor = "purple"; break;
    case "#FFE51400": currentAccentColor = "red"; break;
    case "#FF00ABA9": currentAccentColor = "teal (viridian)"; break;

    // Lime changed to #FFA2C139 in Windows Phone OS 7.1.
    case "#FF8CBF26": 
    case "#FFA2C139": currentAccentColor = "lime"; break;

    // Magenta changed to # FFD80073 in Windows Phone OS 7.1.
    case "#FFFF0097": 
    case "#FFD80073": currentAccentColor = "magenta"; break;

    // #FFF9609 (previously orange) is named mango in Windows Phone OS 7.1.
    case "#FFF09609": currentAccentColor = "mango (orange)"; break;

    // Mobile operator or hardware manufacturer color
    default: currentAccentColor = "custom eleventh color"; break;
}

// Write the current accent color.
textBlock2.Text = "accent color = " + currentAccentColor;
