EnumStringValues

Library to allow conversion between an Enum Value and a string, in both directions. Implemented as an Attribute to be applied to Enum fields to define a string, and methods to extract the defined string given the enum or provide the matching given a string. Enum name is registered as a default stringValue everywhere. All operations are cached, to save on reflection overheads. But this can be disabled, with EnumExtensions.Behaviour.UseCaching, if desired.

Breaking Change Log (3.0 → 4.0)

  • .NET 3.5 support is entirely dropped. Please use the last 3.2.* build.
  • There are 2 changes which change behaviour of the library, though do not cause compile-time errors. They are:
    • Caching.
      • This is now active by default, which will change the CPU vs RAM profile of EnumStringValues. See docs below for how to disable caching, if desired.
    • Use of Enum Literal Name.
      • The literal name is now always included by default, which might affect behaviour in some edge cases.
      • Again, this behaviour is controllable, see docs below for how to adjust this behaviour, if desired.

Breaking Change Log (2.0 → 3.0)

The Deprecated ParseStringValueToEnum method has been removed. Please use ParseToEnum instead.

Version 4.0.2
      - Re-Release without DEBUG enabled (4.0.1 was unintentionally a DEBUG build)
   Version 4.0.1
      - Fix MemoryLeak bug, in a MaliciousUser edge-case.
   Version 4.0.0
      - Change default behaviours.
         - Caching is enabled by default.
         - Enum literal name is AlwaysIncluded by default.
         - See docs and release notes for versions 3.1.0 and 3.2.0, to change these setting.
      - Add thread-safety.
         - Caching dictionaries were not thread-safe; now they are.
      - Drop support for .NET frameworks prior to .NET 4
         - Required, in order to implement thread-safety.
         - Note that version 3.2.0 does support .NET 3.5 and has all the same functionality available, but without thread-safety and with different default Behaviour.
         - Bug fixes will be applied to v 3.2.* but no new features will support .NET 3.5. Please contact me if you wish to argue otherwise.
   Version 3.2.0
      - Add direct control over how the enum's literal name is used.
         - By default behaviour remains the same - literal name is used if and only if there are no StringValue attributes defined.
         - Option is added to allow for literal name to always be included (as lowest priority) or never be included.
         - Control is modified via: `EnumExtensions.Behaviour.ShouldIncludeUnderlyingName = UnderlyingNameUsed.Always`
         - Default will be changed to 'Always' in v4.0
   Version 3.1.0
      - Add option of caching all work done from all end points.
         - Caching is opt-in; accessed by setting EnumExtensions.Behaviour.UseCaching = true.
         - Caching is NOT thread-safe (to maintain .NET 3.5 support)
         - Thread-safety will be added in v4.0
   Version 3.0.1
      - Update codebase to C# 7.3 and thus add System.Enum constraints on all typed methods.
         - Only impact should be to convert run-time errors into compile-time errors
   Version 3.0
      - Convert the project to .Net Standard 2.0
      - Remove the Obsolete `ParseStringValueToEnum` method. Please use `ParseToEnum`
