Figure 9-3. Structure of a switch statement Switch labels have the following form: case ConstantExpression : Keyword Switch label terminator The flow of control through the structure in Figure 9-3 is the following: The test expression, TestExpr, is evaluated at the top of the construct. If the value of TestExpr is equal to the value ConstExpr1, the constant expression in the first switch label, then the statements in the statement list following the switch label are executed, until the break statement is encountered. Each switch section must end with a break statement (or a goto statement, as discussed later). The break statement branches execution to the end of the switch statement. The default section is optional, but must include a break statement, if included.

My own books on ASP.NET are Pro ASP.NET 4 in C# 2010 (with Matt MacDonald) and ASP.NET In Context. The first one is a very comprehensive and detailed coverage of ASP.NET, while the In Context book is more focused on the functionality that programmers use regularly. I have also written Pro ASP.NET MVC 3 Framework (with Steven Sanderson) that covers an advanced ASP.NET feature (that I don t cover in this book) called MVC. I also like Christian Wenz s ASP.NET AJAX book, published by O Reilly.

view does not reflect our customizations. One other thing, while I m at it the ActivityDesigner and ActivityDesignerTheme classes are only refreshed when you shut down Visual Studio. So if you make changes to this class and rebuild your project, you won t see the changes until you restart Visual Studio.

THE BOOK YOU HOLD in your hands is the culmination of months of hard work and a passionate desire to create a high-quality, informative text on serviceoriented architecture using Web Services Enhancements 2.0. Like all major projects, it would not have been possible without the hard work and dedication of a great many people. First and foremost I would like to thank the team at Apress: Gary Cornell, Ewan Buckingham, Tracy Brown Collins, Ami Knox, Grace Wong, Glenn Munlawin, Kari Brooks, and all of the editorial and production staff who worked on this book. In addition I am very grateful to Keith Ballinger for his reviews and comments, and for appreciating my book enough to write a foreword. A big thanks goes out to all of the people who spent time discussing the material with me and giving me new insights and ideas on how to approach it. Finally, I reserve my BIGGEST thanks of all to the hard work and dedication of my friends, colleagues, and technical reviewers: Mauricio Duran, Fernando Gutierrez, and Kenneth Tu. They rock. We roll. Together we rock n roll!

public int CalculateFuelForTrip(int tripDistance) { return tripDistance / MilesPerGallon; } } class TripPrinter { public void PrintTripDetails(Car myCar) { int[] distances = { 50, 100, 250, 500 }; Console.WriteLine("--- Trip details ---"); foreach (int dist in distances) { Console.WriteLine("{0} miles requires: {1} gallons", dist, myCar.CalculateFuelForTrip(dist)); } } } The Car class is a simplified version of the class we used previously in the chapter. The TripPrinter class contains a single method called PrintTripDetails, which takes a Car object as a parameter and calls the CalculateFuelForTrip method to determine how much fuel is required for trips of different lengths. (This method uses an array, which is explained in 13, and a foreach loop, explained in 4.) The important point to note here is that the TripPrinter class has been written to work with Car objects and specifically calls a method defined in the Car class. The following statements demonstrate these two classes being used together: using System; class PolymorphismTest { static void Main(string[] args) { // create an instance of Car Car myCar = new Car("Adam Freeman", "Black", 30); // call the TripPrinter.PrintTripDetails method TripPrinter printer = new TripPrinter(); printer.PrintTripDetails(myCar); // wait for input before exiting Console.WriteLine("Press enter to finish"); Console.ReadLine(); } } This class creates an instance of Car and uses it to call the PrintTripDetails method on a TripPrinter object. The results of compiling and running this code are as follows:

#import "TicTacToeViewController.h" @interface Cell : UIView { TicTacToeViewController *viewController; BOOL cellTappedRemote; BOOL cellTappedLocal; } -(id)initWithHPos:(NSInteger)i vPos:(NSInteger)j sender:(TicTacToeViewController *)sender; -(void)remoteTap; -(void)clearCell; @end

I called the Seek method in Listing 20-16 because I wanted to reposition the cursor at the start of the stream so that I can read the values that I have previously written. The following statements read the data in the stream, one byte value at a time: for (int i = 0; i < 5; i++) { Console.WriteLine("Read value: {0}", myStream.ReadByte()); } As each value is read, the cursor is moved to the next position in the data sequence, which means that at the end of the for loop, the cursor is back at the end of the Stream, in the same position as shown by Figure 20-3. When you read data using the ReadByte method, the result will be the next value in the stream or -1 if you have reached the end of the stream.
