遍历所有颜色? [英] Loop through all colors?

问题描述

我正在使用C#(Windows-Phone-7)开发一个应用程序，并且正在尝试做一些让我感到困惑的简单事情.

I'm working on an app in C# (Windows-Phone-7), and I'm trying to do something simple that has me stumped.

我想循环显示每种颜色，并将颜色名称写到文件中(以及其他内容).

I want to cycle through each Color in Colors, and write out the Color name to a file (along with other stuff).

我有最简单的代码，虽然我知道这是行不通的，但是我还是写了入门书:

I have the simplest bit of code, which I know will not work, but I wrote to get started:

foreach (Color myColor in Colors)
{
}

当然，这给了我以下语法错误:

Of course, this gives me the following syntax error:

"System.Windows.Media.Colors"是类型"，但其用法类似于变量".

'System.Windows.Media.Colors' is a 'type', but is used like a 'variable'.

有没有办法做到这一点?看起来真的很简单！

Is there a way to do this? It seems really simple!

推荐答案

您可以使用此帮助器方法获取每种颜色的名称/值对的字典.

You can use this helper method to get a Dictionary of each Color's name/value pair.

public static Dictionary<string,object> GetStaticPropertyBag(Type t)
    {
        const BindingFlags flags = BindingFlags.Static | BindingFlags.Public | BindingFlags.NonPublic;

        var map = new Dictionary<string, object>();
        foreach (var prop in t.GetProperties(flags))
        {
            map[prop.Name] = prop.GetValue(null, null);
        }
        return map;
    }

使用于:

var colors = GetStaticPropertyBag(typeof(Colors));

foreach(KeyValuePair<string, object> colorPair in colors)
{
     Console.WriteLine(colorPair.Key);
     Color color = (Color) colorPair.Value;
}

帮助方法的信用额转到如何我使用反射得到了C#静态类属性的名称?
