StrEnum is a tiny library that allows to create string-based enums in C#. Give your data more meaning by using strings over numerics while retaining type safety.

StrEnum enums can be used with the various libraries and frameworks:

StrEnum targets .NET Standard 2.0 and has no external dependencies.


You can install StrEnum using the .NET CLI:

dotnet add package StrEnum


Create a class that inherits from the StringEnum<TEnum> class and use the Define method to define the members:

public class Sport : StringEnum<Sport>
    public static readonly Sport TrailRunning = Define("TRAIL_RUNNING");
    public static readonly Sport RoadCycling = Define("ROAD_CYCLING");

You can now use your string enum as you would a regular enum:

var sport = Sport.TrailRunning;

sport.ToString(); // TrailRunning

(string)sport; // TRAIL_RUNNING

sport == Sport.RoadCycling; // false


Use the Parse method to convert the name or a string value to the corresponding string enum member:

Sport.Parse("TrailRunning"); // Sport.TrailRunning

Sport.Parse("TRAIL_RUNNING"); // Sport.TrailRunning

Sport.Parse("Quidditch"); // throws an ArgumentException: "Requested name or value 'Quidditch' was not found."

To make Parse ignore case, pass true as the second argument:

Sport.Parse("trailrunning", ignoreCase: true); // Sport.TrailRunning

Sport.Parse("trail_running", ignoreCase: true); // Sport.TrailRunning

Use the TryParse method when you want to check whether the provided string can be converted to a string enum:

Sport.TryParse("TrailRunning", out var trailRunning); // true

(string)trailRunning; // Sport.TrailRunning
Sport.TryParse("Quidditch", out var quidditch); // false

quidditch == null; // true

Listing members

Use the GetMembers method to list the members of a string enum in the order of definition:

Sport.GetMembers(); // [Sport.TrailRunning, Sport.RoadCycling]

Adding members after initialization

The Define method can be used to add members to a string enum after it has been initialized. Since Define is protected, you need to expose it to the client code first:

public class FictionalSport : StringEnum<FictionalSport>
    public static readonly FictionalSport Quidditch = Define("QUIDDITCH");

    public static FictionalSport Add(string name, string value)
        return Define(value, name);

You need to provide both name and value for the members defined in such way:

var podracing = FictionalSport.Add("Podracing", "PODRACING");

(string)podracing; // PODRACING

FictionalSport.Parse("Podracing").ToString(); // Podracing
