On page 41, it should be
Console.WriteLine( Sum (new int[] {1, 2, 3, 4} ) );
(which is equivalent to Console.WriteLine(Sum (1, 2, 3, 4)); )
Rather than Console.WriteLine(new int[] {1, 2, 3, 4});

3rd code fragment, just above section "Optional Parameters"

The code example, accompanying the discussion of the params modifier, includes this line of code:

Console.WriteLn (Sum (1, 2, 3, 4 ));

The authors then state that the given line is semantically equivalent to the following line:

Console.WriteLn (new Int[] { 1, 2, 3, 4 } );

I believe that last line ought rather to be:

Console.WriteLn (Sum (new Int[] { 1, 2, 3, 4 } ));

Line 6 in the table


-- Post-increment --x


I think it should be Pre-decrement.

Thanks

immediately following the Conditional Or operator

The Null Coalescing operator, described on pages 135 and 136, is missing from the operator table on pages 46 through 48. It should immediately follow the Conditional Or operator.

First paragraph, direcatly after the "note" section

The word "namespace" is incorrectly spelled as "namepace".

The sentence is:
The "namepace" keyword defines a namespace for types within that block.

var numbers = new List<int> { 1 };
numbers.Add (1);
IEnumerable<int> query = numbers.Select (n => n * 10);
numbers.Add (2); // Sneak in an extra element
foreach (int n in query)
Console.Write (n + "|"); // 10|20|


The list ends up being size 3, so the correct output is:

10|10|20|


not

10|20|

code block after 1st para

Confirming that the same error mentioned above by Craig for page 147 of the PDF version applies to the Print version as well (as of the 3rd Release).
