How to Best Represent String Values in Enums?

enumerated string indicates

enumeration is a powerful tool for a set of naming constants. However, when you need to access the string representation of the enumeration value, the default behavior may be limited.

Custom solution

The custom solution provided by the user involves the creation of a custom attribute named "Stringvalue" and adds it to the enumeration. This attribute stored the enumerated value string indicates that the GetStringValue method can be used to retrieve. Although this solution is valid, it will increase additional complexity and require additional code to maintain.

Type safe enumeration mode

The more flexible and secure method is to use the type safe enumeration mode. In this mode, the enumeration is defined as a sealing class, where the static field indicates the enumeration value. For example:

Using this method, you can use simply to apply for the Tostring method to access the enumeration string. In addition, it can define the explicit and implicit type conversion so that it can be easily converted between the string and the enumeration value.

Conclusion

<code class="language-c#">public sealed class AuthenticationMethod
{
    private readonly string name;
    private readonly int value;

    public static readonly AuthenticationMethod FORMS = new AuthenticationMethod(1, "FORMS");
    public static readonly AuthenticationMethod WINDOWSAUTHENTICATION = new AuthenticationMethod(2, "WINDOWS");
    public static readonly AuthenticationMethod SINGLESIGNON = new AuthenticationMethod(3, "SSN");

    private AuthenticationMethod(int value, string name)
    {
        this.name = name;
        this.value = value;
    }

    public override string ToString()
    {
        return name;
    }
}</code>

Type safe enumeration mode provides a more flexible and type secure way to represent enumeration with string values. It eliminates the need for custom attributes and provides a consistent and intuitive way to access the enumeration string representation.
