Identify if a Type is *either* of int or Nullable
Reflection code.
I can check if
myTypeObject == typeof(decimal) || myTypeObject == typeof(decimal?)
Is there any way to do that without repeating decimal?
I'm guessing something along the lines of:
myRealTypeObject = myTypeObject.IsNullable() ? myTypeObject.GetTypeInsideNullability() : myTypeObject;
myRealTypeObject == typeof(decimal)

You can use Nullable.GetUnderlyingType which returns null if the input type is not nullable:
var myRealTypeObject = Nullable.GetUnderlyingType(myTypeObject) ?? myTypeObject;
if instead you have have some object you want to check you can just use is (or as):
bool isDecimal = boxedDecimal is decimal?;

it's specifically reflection code (EF type conventions, if you care), but the 1st half is exactly what I was hoping for.

I don't think repeating the word decimal is that bad. You can always extract that into a method.
But anyway, here is a way to check that doesn't involve two decimal:
Type d = typeof(decimal);
bool check = myTypeObject == d || myTypeObject == typeof(Nullable<>).MakeGenericType(d);
If you want it as an extension method:
public static bool IsTypeOrNullable(this Type t, Type u) {
return t == u || t == typeof(Nullable<>).MakeGenericType(u);
}
// usage: myTypeObject.IsTypeOrNullabel(typeof(decimal))
