Absolutely – use Nullable.GetUnderlyingType
:
if (Nullable.GetUnderlyingType(propertyType) != null)
{
// It's nullable
}
Note that this uses the non-generic static class System.Nullable
rather than the generic struct Nullable<T>
.
Also note that that will check whether it represents a specific (closed) nullable value type… it won’t work if you use it on a generic type, e.g.
public class Foo<T> where T : struct
{
public Nullable<T> Bar { get; set; }
}
Type propertyType = typeof(Foo<>).GetProperty("Bar").PropertyType;
// propertyType is an *open* type...
