How to iterate Cascading Object List?

Question

Hi All,
I faced an issue when iterate a List like below,
class Program
private List<Question> questionList = new List<Question>();
// Add serveral questions in questionList.
static void Main(string[] args)
// Currently, I got a Question instance. and I will loop in questionList. Since as you can see, the Question Object is a Cascading object.
// How to Loop the question the Question List.
public class Question
public List<Question> Questions { get; set; }
public string Title { get; set; }
public string Score { get; set; }
Thanks a lot.

Hi All,
Sorry for my bad English. I am not a native English Speaker. What I want to do is remove the item in the Question list.
List<Question> QuestionList = new List<Question>();
Question Q11 = new Question()
Title = "1.1",
Score = 5,
Question Q12 = new Question()
Title = "1.2",
Score = 5,
Question Q13 = new Question()
Title = "1.3",
Score = 5,
List<Question> Q13List = new List<Question>();
Question Q131 = new Question()
Title = "1.3.1",
Score = 5,
Question Q132 = new Question()
Title = "1.3.2",
Score = 5,
List<Question> Q132List = new List<Question>();
Question Q1321 = new Question()
Title = "1.3.2.1",
Score = 5,
Question Q1322 = new Question()
Title = "1.3.2.2",
Score = 5,
Question Q1323 = new Question()
Title = "1.3.2.3",
Score = 5,
Q132.Questions = Q132List;
Q13List.Add(Q131);
Q13List.Add(Q132);
Q13.Questions = Q13List;
List<Question> Q1List = new List<Question>();
Q1List.Add(Q11);
Q1List.Add(Q12);
Q1List.Add(Q13);
Question Q1 = new Question()
Title = "First One",
Score = 25,
Questions = Q1List,
Question Q2 = new Question()
Title = "Second",
Score = 25,
Question Q3 = new Question()
Title = "Third",
Score = 25,
QuestionList.Add(Q1);
QuestionList.Add(Q2);
QuestionList.Add(Q3);
// The question need delete in Question List. How should I found the Question in the QuestionList.
Question needDeleteQuestion = new Question()
Title = "1.3.2",
Score = 5,
Thank you very much guys for your help.
