UNCONFIRMED  errors and comments from readers: 

{49} Second code line from the bottom;
int caseSensitiveResult = string.Compare( lowerCase,
StringComparison.CurrentCulture ) ;

should be:

int caseSensitiveResult = string.Compare( lowerCase, upperCase,
StringComparison.CurrentCulture ) ;


[61] mid-page;
The second to last line of the code examples is:

Colors actualEnum = (Colors)Colors.Parse( typeof( Colors ), colorString ) ;

Should be:

Colors actualEnum = (Colors)Enum.Parse( typeof( Colors ), colorString ) ;


{801} Code for POST overload;
The code as printed throws a ProtocolViolationException on the line ending in 
'httpRequest.GetRequestStream())' because the Method property of the httpRequest object is set to GET.

This is fixed by adding 'httpRequest.Method = "POST"' anywhere between the initialization of the 
httpRequest object and the offending line.


{838} 2nd paragraph under "Discussion" heading;
The code snippet does not match the program on the previous page. The snippet creates an XPathDocument 
from a MemoryStream object. The complete program creates an XPathDocument from a StringReader object.

The text above the code matches the snippet, which means it is also incorrect (assuming the complete 
program on the previous page is correct.)


{879} 7th line;
I think you forgot to define _syncRoot. I'm not finshed with testing the code, but I defined it as:

private object _syncRoot;

and then assigned the value in the "MyTcpServer" constructor, like

_syncRoot = this;
