Generic Type Constraint for integral_type

Question

I have a Generic method for which I need to constrain the type to integral_type (https://learn.microsoft.com/en-us/dotnet/csharp/language-reference/language-specification/types#836-integral-types). However, the best I could find was to use where U : struct, but this allows a lot more than just integral types. Is there a way to constrain the type to integral types?

Answer 1

you can constrain to value types. depending on the parameter mix, you might want to try method overloading:

    private void _CallIntType<T>(T i) =>  Console.WriteLine(i);

    public void CallIntType(long i) => _CallIntType(i); 
    public void CallIntType(ulong i) => _CallIntType(i); 

this makes use the compiler up casting.
