Conversion enables you to compare and copy values between different types. Implicit conversion happens automatically and behaves differently in Visual Basic and C#. C# allows implicit conversion for only narrowing conversions, where no information could be lost. Visual Basic allows implicit conversion for both narrowing and widening conversions. When values are converted from a value type to a reference type, it is considered boxing. Unboxing occurs if you assign a reference object to a value type.

You have recently accepted a job as an internal application developer in the information technology department of an enterprise healthcare company. Your first task is to design an internal application that employees will use to manage information about customers (whom everyone calls subscribers ), their current plans, medications, and chosen doctors. Answer your manager s questions about your design choices. 1. We need to manage information about both subscribers and doctors. How will you do this Will you have one class for both, two separate classes, or what 2. Our employees need to search for groups of subscribers or doctors. For example, if a doctor retires, we need to contact all that doctor s subscribers and assist them in finding a new physician. Similarly, we contact doctors annually to renew their contracts. How can you store a group of subscribers or doctors in your application 3. One of the tasks your application will perform is generating mailing labels for groups of subscribers or doctors. Is there any way that you can write a single method that will handle addresses for both subscribers and doctors How will you implement this 4. The privacy of our information is extremely important to us. Our database developer is going to restrict permissions on the database to prevent unauthorized users from gaining access. If a user s privileges are rejected, I d like you to instruct the user to contact their manager to gain access. How will you handle it if a database query is rejected for insufficient privileges

Suggested Practices
To help you successfully master the exam objectives presented in this chapter, complete the following tasks.
Manage Data in a .NET Framework Application by Using .NET Framework 2.0 System Types
For this task, you should complete at least Practices 1 and 2. If you want a better understanding of how generics perform in the real world, complete Practice 3 as well.
Practice 1 Open the last project you created, and add exception handling to
your code. Unless performance is a higher priority than reliability, all code outside of value type declarations should be in a Try block.

Practice 2 Create a linked-list generic class that enables you to create a chain of
different object types.
Practice 3 Create two classes with identical functionality. Use generics for the
first class, and cast the second class to Object types. Create a For loop that uses the class over thousands of iterations. Time the performance of both the generic class and the Object-based class to determine which performs better. You can use DateTime.Now.Ticks to measure the time.
Implement .NET Framework Interfaces to Cause Components to Comply with Standard Contracts
For this task, you should complete all three practices to gain experience implementing common interfaces with real-world classes and schema.
Practice 1 Create a custom class that implements the necessary interfaces to
allow an array of the class to be sorted.
Practice 2 Create a custom class that can be converted to common value types. Practice 3 Create a custom class that can be disposed of using the IDisposable
.Dispose method.
Control Interactions Between .NET Framework Application Components by Using Events and Delegates
For this task, you should complete both Practices 1 and 2.
Practice 1 Open the last Windows Forms application you created, and examine
the code Visual Studio automatically generated to respond to user interface events.
Practice 2 Create a class that throws an event and derives a custom class based
on EventArgs. Then create an assembly that responds to the event.
Take a Practice Test
The practice tests on this book s companion CD offer many options. For example, you can test yourself on just the content covered in this chapter, or you can test yourself on all the 70-536 certification exam content. You can set up the test so that it closely
