c# - 如何在 WinRT 中枚举颜色？

Question

在非 WinRT 中枚举颜色是一个常见的问题，答案很简单。但是，由于颜色“ENUM”实际上只是一个具有静态“颜色”属性的类，您不能在 WinRT 中使用标准方法。

如何在 WinRT 中枚举颜色？

Answer 1

像这样:

在 WinRT 中枚举颜色需要使用 System.Reflection，这样您就可以获取容器类“Colors”中子类化的静态属性。像这样:

Dictionary<string, Windows.UI.Color> Colors()
{
    var _Colors = typeof(Windows.UI.Colors)
        // using System.Reflection;
        .GetRuntimeProperties()
        .Select(c => new
        {
            Color = (Windows.UI.Color)c.GetValue(null),
            Name = c.Name
        });
    return _Colors.ToDictionary(x => x.Name, x => x.Color);
}

注意:如果您不喜欢反射(出于某种原因)，那么也没有什么可以阻止您手动编写可枚举颜色的代码。创建一个“动态”颜色列表真的只是为了花哨的缘故——颜色不会更新。只写 list !

在这里，我为你做了:

public class ColorList : List<Windows.UI.Color>
{
    public ColorList()
    {
        this.Add(Windows.UI.Colors.AliceBlue);
