70-536 NET Foundations #29

Hey Now,

Please feel free to check out my MCTS 70-536 reference page on Chris Catto.com. It’s a page with a summary of all of my posts.
As I study for this test I thought this would be good to post on to learn the content & others would be able to view & comment on it.

This content below is from some practice questions from the internet & not sure the answers are correct. There were over 200 questions & some duplicates, I hope to study all of them. I’ve also added some of my notes to these so any line starting with K8 (my nickname, first syllable of Catt o ) are my comments.

Thx,

Catto

Question: 150

You create a class library that contains the class hierarchy defined in the following code segment.

(Line numbers are included for reference only.)
01 public class Group {
02 public Employee[] Employees;
03 }
04 public class Employee {
05 public string Name;
06 }
07 public class Manager : Employee {
08 public int Level;
09 }

You create an instance of the Group class. You populate the fields of the instance. When you attempt to serialize the instance by using the Serialize method of the XmlSerializer class, you receive InvalidOperationException. You also receive the following error message: "There was an error generating the XML document." You need to modify the code segment so that you can successfully serialize instances of the Group class by using the XmlSerializer class. You also need to ensure that the XML output contains an element for all public fields in the class hierarchy. What should you do?

A. Insert the following code between lines 1 and 2 of the code segment:
[XmlArrayItem(Type = typeof(Employee))]
[XmlArrayItem(Type = typeof(Manager))]

B. Insert the following code between lines 1 and 2 of the code segment:
[XmlElement(Type = typeof(Employees))]

C. Insert the following code between lines 1 and 2 of the code segment:
[XmlArray(ElementName="Employees")]
