Odin.System.StringEnum, part of the OrDinary INfrastructure libraries, provides enum-like behaviour for a set of string values via StringEnum, as well as a useful StringEnumMemberAttribute.

Getting Started

1 - Define your string 'enum'

Create your string 'enum' class by inheriting from StringEnum and adding public string constant members.

 public class LoaderTypes : StringEnum<LoaderTypes>
 {
 public const string File = "FILE";
 public const string DynamicSql = "DYNAMIC-SQL";
 }

2 - Use the class like an enum

 if (loaderOptions.LoaderType == LoaderTypes.DynamicSql)
 ... 

3 - Use the static HasValue(string value) convenience method

 bool memberExists = LoaderTypes.HasValue("CUSTOM"); // returns false

4 - Enumerate all values via the static Values property

 string message = $"Valid members are: {string.Join(" | ", LoaderTypes.Values)}"

5 - There is also a Validation attribute

 public record LoaderEditModel : IValidatableObject
 {
 [Required(AllowEmptyStrings = false)]
 [StringEnumMember<LoaderTypes>]
 public required string Loader { get; set; }
 ...
 }
