How can I use enum in C# for storing string constants? [duplicate]

by

Enum constants can only be of ordinal types (int by default), so you can’t have string constants in enums.

When I want something like a “string-based enum” I create a class to hold the constants like you did, except I make it a static class to prevent both unwanted instantiation and unwanted subclassing.

But if you don’t want to use string as the type in method signatures and you prefer a safer, more restrictive type (like Operation), you can use the safe enum pattern:

public sealed class Operation
{
    public static readonly Operation Name1 = new Operation("Name1");
    public static readonly Operation Name2 = new Operation("Name2");

    private Operation(string value)
    {
        Value = value;
    }

    public string Value { get; private set; }
}
