关联枚举在C＃中的字符串 [英] Associating enums with strings in C#

问题描述

我知道下面是不可能的，因为它必须是一个int

I know the following is not possible because it has to be an int

enum GroupTypes
{
    TheGroup = "OEM",
    TheOtherGroup = "CMB"
}

这是我的数据库我得到科钦prehensive codeS（贴牌和招商银行的）的字段。我想使这个领域成为一个枚举或别的东西可以理解的。因为目标是可读性的解决办法应该是简洁。
我有什么其他选择？

From my database I get a field with incomprehensive codes (the OEM and CMB's). I would want to make this field into an enum or something else understandable. Because the target is readability the solution should be terse.
What other options do I have?

推荐答案

我喜欢的一类，而不是使用方法的属性，因为它们看起来更枚举等。

I like to use properties in a class instead of methods, since they look more enum-like.

下面是一个记录器一个例子：

Here's a example for a Logger:

public class LogCategory
{
 private LogCategory(string value) { Value = value; }

 public string Value { get; set; }

 public static LogCategory Trace { get { return new LogCategory("Trace"); } }
 public static LogCategory Debug { get { return new LogCategory("Debug"); } }
 public static LogCategory Info { get { return new LogCategory("Info"); } }
 public static LogCategory Warning { get { return new LogCategory("Warning"); } }
 public static LogCategory Error { get { return new LogCategory("Error"); } }
}

传入类型安全的字符串值作为一个参数：

public static void Write(string message, LogCategory logCategory)
{
   var log = new LogEntry { Message = message };
   Logger.Write(log, logCategory.Value);
}

用法：

Logger.Write("This is almost like an enum.", LogCategory.Info);
