How to iterate the List in Reflection

I am having one property called Students which is of type List<Student>.

In reflection i can get the value of Students Property.

Now the problem is How to iterate the List of Students.

I need to check whether StudentID [ some value ] is in that collection.

var collection = studentPro.GetValue(studentObj,null);

//I need to iterate like this,

foreach(var item in collection)
{
     if(item.StudentID == 33)
         //Do stuff
}

Please help me.
