在 C# 中将字符串转换为画笔/画笔颜色名称 [英] Convert string to Brushes/Brush color name in C#

问题描述

我有一个配置文件，开发人员可以在其中通过传入字符串来指定文本颜色:

I have a configuration file where a developer can specify a text color by passing in a string:

 <text value="Hello, World" color="Red"/>

与其用一个巨大的 switch 语句来查找所有可能的颜色，不如使用 System.Drawing.Brushes 类中的属性，这样我在内部可以这样说:

Rather than have a gigantic switch statement look for all of the possible colors, it'd be nice to just use the properties in the class System.Drawing.Brushes instead so internally I can say something like:

 Brush color = Brushes.Black;   // Default

 // later on...
 this.color = (Brush)Enum.Parse(typeof(Brush), prasedValue("color"));

除了 Brush/Brushes 中的值不是枚举.所以 Enum.Parse 没有给我带来快乐.建议?

Except that the values in Brush/Brushes aren't enums. So Enum.Parse gives me no joy. Suggestions?

推荐答案

回顾所有以前的答案，将字符串转换为颜色或画笔的不同方法:

Recap of all previous answers, different ways to convert a string to a Color or Brush:

// best, using Color's static method
Color red1 = Color.FromName("Red");

// using a ColorConverter
TypeConverter tc1 = TypeDescriptor.GetConverter(typeof(Color)); // ..or..
TypeConverter tc2 = new ColorConverter();
Color red2 = (Color)tc.ConvertFromString("Red");

// using Reflection on Color or Brush
Color red3 = (Color)typeof(Color).GetProperty("Red").GetValue(null, null);

// in WPF you can use a BrushConverter
SolidColorBrush redBrush = (SolidColorBrush)new BrushConverter().ConvertFromString("Red");
