C-Sharp (C#) Group: Reflection Help

I have a slight problem.  I am trying to get object
properties
dynamically.  This just screams reflection, the problem I'm
having is
getting the right property.  The properties I need from the
object are
in another object within the current object.  Specifically,
I have an
object ScheduleCountView, within it is CourseSection,
Course, and
Code.

I try to get the CourseSection.Course.Code property with
type.GetProperty("CourseSection.Course.Code"),
where type equals
ScheduleCountView, and for soem reason it always returns
null.  Does
anybody have any suggestions on how to get the information I
need from
the object?  Thanks in advance.


Jimmy

All I want from the object is the value in
CourseSection.Course.Code.
I've set up a loop to go through the types listed in a
string array
until it gets to Code and when I try to get the value I no
longer have
the correct object to pass in as an parameter.  It should
also be
noted that I need this to be as dynamic as possible, this
program
won't always be working with a CourseSection object.

I must not be doing it right then.

string[] strTypes = path.Split('.');
Type type = item.GetType();
for (int i = 0; i < strTypes.Length - 1; i++)
{
   PropertyInfo prop = type.GetProperty(strTypes[i]);
   type = prop.PropertyType;
}

PropertyInfo targetProperty =
type.GetProperty(strTypes[strTypes.Length - 1]);
string value = targetProperty(item, null);

The last line gives me an error saying "Object does not
match target
type."  More specifically, with what you've suggested,
how do I
retrieve the object from the type?
