return Object<byte> after checking typeof(T) == typeof(byte)

Is this possible or is there a way to sort of do this? I'm trying to do something like this:

if (typeof(TValue) == typeof(sbyte)) {
    return new MyObject<sbyte>(defaultValue, getValue, setValue, (x) => sbyte.Parse(x));
}

if (typeof(TValue) == typeof(sbyte)) {
    return new MyObject<sbyte>(defaultValue, getValue, setValue, (x) => sbyte.Parse(x));
}

Yeah The constructor takes Func<string, TValue> fromString That what I think i'll do, just use object instead of TValue

You can do (TValue)(object)val if (TValue)val doesn’t work. The JIT recognizes this pattern and will throw away the cast.

It's for a serialisable property I'm wondering if constrainting TValue to INumberBase<TValue> would work

jcotton42•2w ago

Do you actually care if it’s a number, or just if it’s parseable?

Just parsable really where TValue : IParsable<TValue> seems to work though Though not sure if it works at runtime, i have way too many errors at the moment
