In a T4 template file, how do I validate the datatype of a property in an entity?

c# entity entity-framework t4 templates

Question

I am customizing my .tt file in EF 4.0. Now as part f customization I need to add some code to a property in POCO class generation, if the property type is Nullable<System.DateTime> or System.DateTime. I am not able to find the proper syntax for comparison.

I have the following code in .tt file.

foreach (EdmProperty edmProperty in entity.Properties.Where(p => p.TypeUsage.EdmType is PrimitiveType && p.DeclaringType == entity))
{
bool isDefaultValueDefinedInModel = (edmProperty.DefaultValue != null);
//Here I need to check whether my edmProperty is Nullable<System.DateTime> or System.DateTime, so that I can insert custom code.
}

Please help.
