Singulink Enums is a tiny (~30KB), highly optimized library with full AOT support that provides generic operations and extension methods for enumeration types. It contains a comprehensive set of the most common enumeration "must haves" that are missing from the .NET runtime. The effect on runtime memory footprint has been pushed to the bare minimum while still supporting common scenarios in the most efficient way possible.
We are a small team of engineers and designers dedicated to building beautiful, functional and well-engineered software solutions. We offer very competitive rates as well as fixed-price contracts and welcome inquiries to discuss any custom development / project support needs you may have.
This package is part of our Singulink Libraries collection. Visit https://github.com/Singulink to see our full list of publicly available libraries and other open-source projects.
The package is available on NuGet - simply install the Singulink.Enums package.
Supported Runtimes: Everywhere .NET Standard 2.0 is supported, including:
- .NET
- .NET Framework
- Mono / Xamarin
You can view the fully documented API on the project documentation site.
The main classes of interest are:
Enum<T>- Static generic helper properties and methods when the enum type needs to specified, i.e. for parsing.EnumExtensions- Extension methods to validate enums and perform operations on values.EnumConverter<T>- Enum converter that can convert enums to and from strings. Separators, enum names and case-sensitivity are fully customizable.
The API is fairly self-explanatory and well documented but here are some examples to show what the library offers:
using Singulink.Enums;
// Get enum names
var enumNames = Enum<ConsoleKey>.Names;
// Get enum values
var enumValues = Enum<ConsoleKey>.Values;
// Get enum field name for a particular value
string backspaceName = ConsoleKey.Backspace.GetName();
// Parse using the default converter
ConsoleKey backspace = Enum<ConsoleKey>.Parse("Backspace");
// Bitwise flag operations
var value = AttributeTargets.Assembly;
value = value.SetFlags(AttributeTargets.Class, AttributeTargets.Method); // set additional flags
bool hasClassAndMethod = value.HasAllFlags(AttributeTargets.Class, AttributeTargets.Method); // true
bool hasClassOrStruct = value.HasAnyFlag(AttributeTargets.Class, AttributeTargets.Struct); // true
IReadOnlyList<AttributeTargets> splitValues = value.SplitFlags(); // 3 separate flags split out
// Create a case-insensitive converter with a non-default separator
var converter = new EnumConverter<AttributeTargets>(opt => {
opt.Separator = " | ";
opt.IgnoreCase = true;
});
// Convert enum value to/from string using the customized converter
string enumString = converter.AsString(value) // "Assembly | Class | Method"
value = converter.Parse(enumString.ToLowerInvariant()); // Assembly, Class and Method flags set
// Create an enum converter that uses the [Display] attribute to get the names
var displayNameConverter = new EnumConverter<YourEnum>(opt => opt.WithDisplayNameGetter());The following is a comparison between Singulink Enums, Enums.Net (v5.0) and operators / system methods (where applicable). Some methods may have subtle behavioral differences.
