C# determine a Nullable property DateTime type when using reflection

Question

I have a question on how to determine an object's Nullable property type.

ObjectA has a property DateTime? CreateDate;

When I iterate through its properties like the following code, how do I check if a property is a Nullable DateTime type?

foreach (PropertyInfo pi in ObjectA.GetType().GetProperties())
{
    //do the compare here
}

Answer 1

pi.PropertyType == typeof(DateTime?)

Answer 2

pi.PropertyType == typeof(Nullable<DateTime>);

Answer 3

Try:

property.PropertyType.Equals(typeof(DateTime?))
