Example 12-1. Publish and subscribe with delegates |
Method Name "SecondChanged" conflicts with prior delegate instance of the same name:
protected virtual void SecondChanged(TimeInfoEventArgs e)
{
if (SecondChanged != null)
{
SecondChanged(this, e);
}
}
Does not compile under Visual Studio 2008. Changing the method name and it's call repairs the problem (I used "SecondChange").
BTW, when reading books Online, I cannot determine a "page number" so I used the Section Number

The second if/else block contains the line:
valueTwo = valueOne + 1;
this was changed from:
valueTwo = valueOne++;
in the 3rd edition of the book (which I also own).
The 3rd edition's output matches the output presented in both books. The 5th edition's does not.

5th: ValueOne: 30 ValueTwo: 31

First program output |
Setting valueTwo to valueOne value,
and incrementing valueOne
ValueOne: 31 ValueTwo: 30
should be
ValueOne: 30 ValueTwo: 31 - because valueTwo is assigned to valueOne + 1 in the second conditional
test in book.

3rd code snippet |
The following code:
ListBox myListBox; // instantiate a ListBox object
did not instantiate the ListBox object because C# compiler will set myListBox null if 'new' operator is ommitted.
So it should be like this:
ListBox myListBox = new ListBox(); // instantiate a ListBox object

This book says:
Thus, if you want to initialize a static member, you must provide an explicit initializer.
but static member is initializable in the static constructor.
So it should be like this:
(snip) you must provide an explicit initializer, or initialize it inside its static constructor.

public int Hour definition |
No comment is made in text about capitalizing the property Hour vs lowercase for private member
variable hour - don't know if this is standard practice to maintain same name but differ only in
case but it would be worth commenting on in text - particularly for people like me who just copied
code from earlier example, then got stack overflows in DisplayCurrentTime, etc. when "Hour" used
instead of "hour" - good OJT in the importance of case, though.

The book incorrectly states that Main() invokes the Cat.HowManyCats() static method. The static method is invoked from Run(), not Main().
This book is excellent, and is especially good when teamed up with Visual C++ 2008 from Microsoft. As an ex-C++ programmer, I find the book a good refresher and also a good point of departure for learning the differences between C++ and C#. I'm 58, but I like C# more than C++ (especially the type-safe and garbage collection features). Who says you can't teach an old Dog() new tricks?

Table 9-2 spanning pp 186-87 |
The Interface item "IColletion<T>" is listed twice in Table 9-2 with two different Purpose
explanations. I believe the Purpose given for the first instance of "ICollection<T>" in the table
is correct, but the Purpose given for the second instance implies, to me, that the intended
Interface item should not be "ICollection<T>", but some other Interface entity. I'm just not sure
what was intended.

This is in the 5th Edition:
The book states:
The default capacity is eight. When you add the 17th element, the capacity is automatically doubled to 16.
Shouldn't this read, when you add the 9th element, the capacity is automatically doubled to 16?
Then the book continues:
If you change the for loop to:
for (int i = 0; i < 9; i++)
...
The output given displays 17 elements. Based on the code, I would expect the output to contain only 9 elements.

2nd class 4th and 5th objects |
In your code and in the explanation of the code you create a function and an object using the same name SecondChanged (public SecondChangeHandler SecondChanged; and protected virtual void SecondChanged(TimeInfoEventArgs e) ).
The problem is is that this code in uncompilable and creates confusion as to what the programmer was trying to make a reference to when calling either one of these objects later on in the code or your description/explanation of the code.

The text continually refers to the VIRTUAL FUNCTION OnSecondChange as the DELEGATE INSTANCE from
the preceding example. I believe the delegate instance SecondChanged is actually intended. This
mistake is made multiple times (consistently) over the 5 pages identified above and was very
confusing until I realized that this was a typo. Hopefully I am not mistaken, as I have continued
my learning with the assumption that this is a typo.

The code and discussion from this point thru the section called 'The event Keyword' on pages 267-268 refer to a method called 'OnSecondChange' that does not exist in the code sample on pages 259 thru 262. I think it should instead refer to 'SecondChanged'.

This book says:
You can't use fully qualified extension method names as you do with a normal method.
but we can invoke the extension method with fully qualified name as a normal method like below (you have written in p298):
System.Linq.Enumerable.Where(names, n => n.StartsWith("D"));
so it should be "can use" rather than "can't use".

Subject: Concerning "Programming C# 3.0" by Jesse Liberty
Hi,
I am currently translating the above mentioned book to swedish for the
swedish edition of it, published by Pagina Forlags AB. While translating
chapter 22 I have found that some errors. At page 525, the example code
in example 22-12 should implement the server, but the printed example
contains the client code. The text states that, "... with the client
following later in Example 22-13". Example 22-13, though, is about web
streams. The complete server code, in fact, is not to be found anywhere
in the chapter.
I just wanted to turn your attention to this problem, if you�d want
correct the error for future editions.
Yours sincerely,
