What exception message do you receive, and why You see the message Invalid parameters. Serialize_People.Person is inaccessible due to its protection level. Only public types can be processed. The error occurs because the Person class is not marked as public. 7. Edit the person class, and mark it as public. Then rebuild the project, and run the following command again:

8. Examine the serialized data to verify that the information you provided on the command line was successfully captured. Why does the age appear in the serialized file even though the age member has the NonSerialized attribute The NonSerialized attribute applies to binary serialization, but it does not affect XML serialization. 9. Now run the command with no parameters to verify that deserialization works properly.

XML serialization provides the interoperability to communicate with different platforms and the flexibility to conform to an XML schema. XML serialization cannot be used to serialize private data or object graphs. To serialize an object, first create a stream, TextWriter, or XmlWriter. Then create an XmlSerializer object and call the XmlSerializer.Serialize method. To deserialize an object, follow the same steps but call the XmlSerializer.Deserialize method. To create a class that can be serialized, specify the class and all members as public, and create a parameterless constructor. You can control XML serialization by using attributes. Attributes can change the names of elements, serialize members as attributes rather than elements, and exclude members from serialization. Use the Xsd.exe tool to create a class that will automatically conform to an XML schema when serialized. Datasets, arrays, collections, and instances of an XmlElement or XmlNode class can all be serialized with XmlSerializer.
Lesson Review
You can use the following questions to test your knowledge of the information in Lesson 2, XML Serialization. The questions are also available on the companion CD if you prefer to review them in electronic form.
NOTE Answers
Answers to these questions and explanations of why each answer choice is right or wrong are located in the Answers section at the end of the book.
1. Which of the following are requirements for a class to be serialized with XML serialization (Choose all that apply.) A. The class must be public. B. The class must be private. C. The class must have a parameterless constructor. D. The class must have a constructor that accepts a SerializationInfo parameter.
Lesson 2: XML Serialization
2. Which of the following attributes would you use to cause a member to be serialized as an attribute, rather than an element A. XmlAnyAttribute B. XMLType C. XMLElement D. XMLAttribute 3. Which tool would you use to help you create a class that, when serialized, would produce an XML document that conformed to an XML schema A. Xsd.exe B. Xdcmake.exe C. XPadsi90.exe D. Xcacls.exe 4. Which of the following attributes should you add to a member to prevent it from being serialized by XML serialization A. XMLType B. XMLIgnore C. XMLElement D. XMLAttribute

Serialization
Lesson 3: Custom Serialization
Custom serialization is the process of controlling the serialization and deserialization of a type. By controlling serialization, it is possible to ensure serialization compatibility, which is the ability to serialize and deserialize between versions of a type without breaking the core functionality of the type. For example, in the first version of a type, there might be only two fields. In the next version of a type, several more fields are added. Yet the second version of an application must be able to serialize and deserialize both types. This lesson describes how to control serialization by implementing your own serialization classes.
After this lesson, you will be able to:
Implement the ISerializable interface to take control over how a class is serialized. Respond to serialization events to run code at different stages of the serialization process. Write code that adjusts serialization and deserialization according to the context. Describe the role of IFormatter.
