Answer 1

If you’re just looking for the list of primitive types, you can find one here:

Or, if you want a method returning a List of primitive types, try this:

public List<Type> GetTypes(){
        return typeof(int).Assembly.GetTypes().Where(t => t.IsPrimitive).ToList();
    }

Since it uses Linq, you will need:

using System.Linq;
