Convert numeric values into enums

Part of DKNet.Fw.Extensions. Use TryConvertToEnum when a boxed numeric value must become a runtime or generic enum value.

using System;
using DKNet.Fw.Extensions.Reflection;

object raw = 1;
if (raw.TryConvertToEnum<State>(out var state))
    Console.WriteLine(state); // Ready
Console.WriteLine(typeof(State).TryConvertToEnum("bad", out _)); // False

public enum State { Unknown, Ready }

TryConvertToEnum unwraps the enum type, converts the input to its numeric underlying type, and creates an enum or returns false for conversion failures.

The runtime overload accepts Type (including nullable enum types), an input object, and an out object?. The generic overload uses where TEnum : struct, Enum and returns out TEnum?. Conversion uses InvariantCulture; InvalidCastException, FormatException and OverflowException become false with a null result.

⚠️ Gotchas & limits

The runtime overload throws ArgumentException when the destination is not an enum.
Conversion does not require a declared enum member: an underlying value such as 99 can succeed.
A member name such as "Ready" is not parsed as an enum name; numeric strings can convert. Use Enum.TryParse for named input.
