Need to find the last type in an expression for sort

Question

User1034446946 posted

Hi

I have a complex data entity, and i am using a static method to determine the type in the method i use

var expression = a => a.DateAdded

var unaryExpression = expression.Body as UnaryExpression;

var propertyExpression = (MemberExpression)unaryExpression.Operand;

then i do

if (propertyExpression.Type == typeof(DateTime))

and everything is fine.

However if the expression used a navigated models field, it fails, eg

var expression = a => a.Parent.DateAdded

Is there a way I can just get the last type and not the whole thing

Any suggestions would be appriciated.

Your question is not clear.  

Syntax to find the last item in a collection.

var last = MyCollection[MyCollection.Count - 1];

Or List<T>.FindLast()
