作者简介

Jennifer Greene

Bestselling O'Reilly authors Jennifer Greene and Andrew Stellman have been building software and writing about software engineering together since they first met in 1998. Their first book, Applied Software Project Management, was published by O’Reilly in 2005. Other Stellman and Greene books for O’Reilly include Beautiful Teams (2009), and their first book in the Head First series, Head First PMP (2007). They founded Stellman & Greene Consulting in 2003 to build a really neat software project for scientists studying herbicide exposure in Vietnam vets. In addition to building software and writing books, they’ve provided training and consulted for companies and spoken at conferences and meetings of software engineers, architects and project managers.

Jenny studied philosophy in college but, like everyone else in the field, couldn’t find a job doing it. Luckily, she’s a great software engineer, so she started out working at an online service, and that’s the first time she really got a good sense of what good software development looked like. She moved to New York in 1998 to work on software quality at a financial software company. She’s managed a teams of developers, testers and PMs on software projects in media and finance since then. She’s traveled all over the world to work with different software teams and build all kinds of cool projects.

Andrew Stellman

Andrew, despite being raised a New Yorker, has lived in Minneapolis, Geneva, and Pittsburgh... twice. The first time was when he graduated from Carnegie Mellon’s School of Computer Science, and then again when he and Jenny were starting their consulting business and writing their first book for O’Reilly. He and Jenny first worked together at a company on Wall Street that built financial software, where he was managing a team of programmers. Over the years he’s been a Vice President at a major investment bank, architected large-scale real-time back end systems, managed large international software teams, and consulted for companies, schools, and organizations, including Microsoft, the National Bureau of Economic Research, and MIT. He’s had the privilege working with some pretty amazing programmers during that time, and likes to think that he’s learned a few things from them.

Mike’s Navigator class has methods to set and modify routes
Use what you’ve learned to build a program that uses a class
Mike gets an idea
Mike can use objects to solve his problem
You use a class to build an object
When you create a new object from a class, it’s called an instance of that class
A better solution...brought to you by objects!
An instance uses fields to keep track of things
Let’s create some instances!

How would you design a zoo simulator?
Use inheritance to avoid duplicate code in subclasses
Different animals make different noises
Think about how to group the animals
Create the class hierarchy
Every subclass extends its base class
Use a colon to inherit from a base class
We know that inheritance adds the base class fields, properties, and methods to the subclass...
A subclass can override methods to change or replace methods it inherited
Any place where you can use a base class, you can use one of its subclasses instead
A subclass can hide methods in the superclass
Use the override and virtual keywords to inherit behavior
A subclass can access its base class using the base keyword
When a base class has a constructor, your subclass needs one, too
Now you’re ready to finish the job for Kathleen!
Build a beehive management system
How you’ll build the beehive management system
Use inheritance to extend the bee management system
Chapter 7 Interfaces and Abstract Classes: Making classes keep their promises
Let’s get back to bee-sics
We can use inheritance to create classes for different types of bees
An interface tells a class that it must implement certain methods and properties
Use the interface keyword to define an interface
Now you can create an instance of NectarStinger that does both jobs
Classes that implement interfaces have to include ALL of the interface’s methods
Get a little practice using interfaces
You can’t instantiate an interface, but you can reference an interface
Interface references work just like object references
You can find out if a class implements a certain interface with “is”
Interfaces can inherit from other interfaces
The RoboBee 4000 can do a worker bee’s job without using valuable honey
is tells you what an object implements; as tells the compiler how to treat your object
A CoffeeMaker is also an Appliance
Upcasting works with both objects and interfaces
Downcasting lets you turn your appliance back into a coffee maker
Upcasting and downcasting work with interfaces, too
There’s more than just public and private
Access modifiers change visibility
Some classes should never be instantiated

An abstract method doesn’t have a body
The Deadly Diamond of Death!
Polymorphism means that one object can take many different forms
Chapter 8 Enums and Collections: Storing Lots of Data
Strings don’t always work for storing categories of data
Enums let you work with a set of valid values
Enums let you represent numbers with names
We could use an array to create a deck of cards...
Arrays are hard to work with
Lists make it easy to store collections of...anything
Lists are more flexible than arrays
Lists shrink and grow dynamically
Generics can store any type
Collection initializers are similar to object initializers
Let’s create a List of Ducks
Lists are easy, but SORTING can be tricky
IComparable<Duck> helps your list sort its ducks
Use IComparer to tell your List how to sort
Create an instance of your comparer object
IComparer can do complex comparisons
Overriding a ToString() method lets an object describe itself
Update your foreach loops to let your Ducks and Cards print themselves
You can upcast an entire list using IEnumerable
You can build your own overloaded methods
Use a dictionary to store keys and values
The dictionary functionality rundown
Build a program that uses a dictionary
And yet MORE collection types...
A queue is FIFO—First In, First Out
A stack is LIFO—Last In, First Out
Chapter 9 Reading and Writing Files: Save the last byte for me!
.NET uses streams to read and write data
Different streams read and write different things
A FileStream reads and writes bytes to a file
Write text to a file in three simple steps
The Swindler launches another diabolical plan
Reading and writing using two objects
Data can go through more than one stream
Use built-in objects to pop up standard dialog boxes
Dialog boxes are just another WinForms control
Dialog boxes are objects, too
Use the built-in File and Directory classes to work with files and directories
Use file dialogs to open and save files (all with just a few lines of code)
IDisposable makes sure your objects are disposed of properly
Avoid filesystem errors with using statements
Trouble at work
Writing files usually involves making a lot of decisions
Use a switch statement to choose the right option
Use a switch statement to let your deck of cards read from a file or write itself out to one
Add an overloaded Deck() constructor that reads a deck of cards in from a file
What happens to an object when it’s serialized?
But what exactly IS an object’s state? What needs to be saved?
When an object is serialized, all of the objects it refers to get serialized, too...
Serialization lets you read or write a whole object graph all at once
If you want your class to be serializable, mark it with the [Serializable] attribute
Let’s serialize and deserialize a deck of cards
.NET uses Unicode to store characters and text
C# can use byte arrays to move data around
Use a BinaryWriter to write binary data
You can read and write serialized files manually, too
Find where the files differ, and use that information to alter them
Working with binary files can be tricky
Use file streams to build a hex dumper
StreamReader and StreamWriter will do just fine (for now)
Use Stream.Read() to read bytes from a stream
Chapter C# Lab The Quest
The spec: build an adventure game
The design: building the form
The architecture: using the objects
Gameplay concerns are separated into the Game object
Building the Game class
Finding common behavior: movement
The Mover class source code
The Player class keeps track of the player
Write the Move() method for the Player
Add an Attack() method, too
Bats, ghosts, and ghouls inherit from the Enemy class
Write the different Enemy subclasses
Weapon inherits from Mover; each weapon inherits from Weapon
Different weapons attack in different ways
Potions implement the IPotion interface
The form brings it all together
The form’s UpdateCharacters() method moves the PictureBoxes into position
The fun’s just beginning!

Chapter 11 Async, Await, and Data Contract Serialization: Pardon the interruption
Brian runs into file trouble
Windows Store apps use await to be more responsive
Use the FileIO class to read and write files
Build a slightly less simple text editor
A data contract is an abstract definition of your object’s data
Use async methods to find and open files

Brian needs his excuses to be mobile
Brian’s code did something unexpected
All exception objects inherit from Exception
The debugger helps you track down and prevent exceptions in your code
Use the IDE’s debugger to ferret out exactly what went wrong in the Excuse Manager
Uh oh—the code’s still got problems...
Handle exceptions with try and catch
What happens when a method you want to call is risky?
Use the debugger to follow the try/catch flow
If you have code that ALWAYS should run, use a finally block
Use the Exception object to get information about the problem
Use more than one catch block to handle multiple types of exceptions
One class throws an exception that a method in another class can catch
Bees need an OutOfHoney exception
An easy way to avoid a lot of problems: using gives you try and finally for free
Exception avoidance: implement IDisposable to do your own cleanup
The worst catch block EVER: catch-all plus comments
Temporary solutions are OK (temporarily)
A few simple ideas for exception handling
Brian finally gets his vacation...
Chapter 13 Captain Amazing The Death of the Object
Your last chance to DO something...your object’s finalizer
When EXACTLY does a finalizer run?
Dispose() works with using; finalizers work with garbage collection
Finalizers can’t depend on stability
Make an object serialize itself in its Dispose()
A struct looks like an object...
...but isn’t an object
Values get copied; references get assigned
Structs are value types; objects are reference types
The stack vs. the heap: more on memory
Use out parameters to make a method return more than one value
Pass by reference using the ref modifier
Use optional parameters to set default values
Use nullable types when you need nonexistent values
Nullable types help you make your programs more robust

Chapter 15 Events and Delegates: What your Code does When You’re Not Looking
Ever wish your objects could think for themselves?
But how does an object KNOW to respond?
When an EVENT occurs...objects listen
One object raises its event, others listen for it...
Then, the other objects handle the event
Connecting the dots
The IDE generates event handlers for you automatically
Generic EventHandlers let you define your own event types
