Please send any errata you
discover or enhancements you
would like to suggest to:
oberg@objectinnovations.com.
Please download the latest version of the
complete code file,
or you may download an update file
that installs over a previous version.
Missing pages 364-365. Some copies of the book were printed missing pages 364 and 365.
You may download a zip file containing a PDF file for these
mising pages.
p. 7 The download code file is a zip file, not a self-extractor
(to avoid problems with an .EXE download being blocked)
p. 103 The code reads on the fourth line
int a[] = {2, 3, 5, 7, 11};
That should be
int [] a = {2, 3, 5, 7, 11};
p. 146 Several other differences between classes and structures should be mentioned here.
Unlike classes:
- Structures cannot have a parameterless (or default) constructor.
- Structures cannot have a default field initializer.
- Structures cannot be derived from other structures.
p. 148 The second to last sentence of the first paragraph should read: "The structure
definition ..." instead of "The class definition ..."
p. 159 Line 10 of the code listing TestReferenceMath.cs should read
ReferenceMath.Calculate(5, 7, ref sum, ref product);
p. 162 The second sentence of the second paragraph of the METHOD OVERLOADING section
should read: "That is, different methods can have the same name, if they have different
signatures."
p. 191 The code reads on the first line
int [] array = {5, 2, 11, 7, 3};
That should be
int [] a = {5, 2, 11, 7, 3};
p. 323 The interfaces ICollection and IList should be as follows:
interface ICollection : IEnumerable
{
int Count {get;}
bool IsSynchronized {get;}
object SyncRoot {get;}
void CopyTo(Array array, int index);
}
and
interface IList : ICollection
{
bool IsReadOnly {get;}
bool IsFixedSize {get;}
object this[int index] {get; set;}
int Add(object value);
void Clear();
bool Contains(object value);
int IndexOf(object value);
void Insert(int index, object value);
void Remove(object value);
void RemoveAt(int index);
}
p. 364 The code file FileDemo.cs is missing one line at line 26.
if (cmd.Equals("cd"))
{
path = iw.getString("path: ");
Directory.SetCurrentDirectory(path);
}
should be
if (cmd.Equals("cd"))
{
path = iw.getString("path: ");
dir = new DirectoryInfo(path);
Directory.SetCurrentDirectory(path);
}
p. 368 The ConsoleThread method is
missing a line of code that prints a
message when the thread terminates,
as illustrated on p. 369. This code
was missing on the original download
file as well. It is fixed in the update file.
public void ConsoleThread()
{
for (int i = 0; i < count; i++)
{
Console.WriteLine("Thread {0}: ticks = {1}", threadId, ticks);
Thread.Sleep(delta);
ticks += delta;
}
Console.WriteLine("Thread {0} is terminating", threadId);
}
p. 379 In the last line, SOAPFormatter should instead by SoapFormatter.
p. 387 The output from running the program should not contain the first line shown.
The output should begin:
woof, woof!!
