C# determine a Nullable property DateTime type when using reflection

问题

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
}

回答1:

pi.PropertyType == typeof(DateTime?)

回答2:

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

回答3:

Try:

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