code sample for iterating over enum values

Enum.GetValues(typeof(Toggle)) returns a System.Array, which cannot be implicitly
cast to an object[]. I had to cast the return value first. Either that, or use the
System.Array object and iterate over it using an IEnumerator.

Lines 16-19

In the regular expression under "Detecting IP addresses",
the line
@"([01]?dd|2[0-4]d|25[0-5])."
is missing a "?" right before "|2[0-4]"
So, the line should look like this:
@"([01]?dd?|2[0-4]d|25[0-5])."
This incorrect string is repeated three more times in the next three lines.

second code example

IEnumerable.GetEnumerator(){
return this.GetEnumerator;
}

The call this.GetEnumerator is missing parenthesis, it should be
this.GetEnumerator();

Person class declaration near the top of the page

Person implements "ISerialization". Isn't this supposed to be "ISerializable" as in
the previous page (158)?

169) 4th paragraph from the end: Retriving a Type Directly;
The example listed for Type.GetType("MyNamespace.MyType , MyAssembly); is inaccurate.
There is no signature for that pram and it is missing a quote.
