How Can I Map C# Enums to Strings?

Mapping C# Enums to Strings: Workarounds

C# enums inherently use integer types, limiting their direct association with strings. However, several effective strategies overcome this limitation.

One approach leverages class properties. By defining a class with string properties, we create a structure that mimics enum behavior:

<code class="language-csharp">public class LogCategory
{
    public string Value { get; private set; }

    public static LogCategory Trace { get; } = new LogCategory("Trace");
    public static LogCategory Info { get; } = new LogCategory("Info");
    // ... other categories
}</code>

This allows for type-safe access to string representations:

<code class="language-csharp">public static void WriteLog(string message, LogCategory category)
{
    Logger.Write(message, category.Value);
}

// Usage:
WriteLog("Log message", LogCategory.Info);</code>

Alternatively, type-safe string parameters can be directly used:

<code class="language-csharp">public static void WriteLog(string message, string category)
{
    // Add validation to ensure category is a valid value
    Logger.Write(message, category);
}

// Usage:
WriteLog("Log message", "Info");</code>

Both methods enhance code readability and flexibility, providing practical alternatives to the limitations of standard enums when string representation is needed. Note that the second approach requires careful validation to ensure only valid string categories are used.
