c# - How to restrict T to value types using a constraint?

Question

I want to restrict the possible types N can take-on using a constraint. I wish to restrict N to be either a int or a decimal.

public static Chart PopulateInto<T, N>(List<T> yAxis, List<N> xAxis) where N : int, decimal
{
    // Do stuff here
}

Any help appreciated...

Answer 1

It's not possible to constrain a generic parameter to a specific value type.

You can however force it to be a value type or struct by adding where N : struct, but that's all.
