This is a much better example. You shouldn't lock this and should lock a
private lock object instead. You shouldn't use volatile since you have more
than one variable that may change at a time. The properties should also lock
the same lock object because you don't want a property to execute in the
You would need to lock as changing the items is not atomic (providing
you want readers to always be in sync i.e. that count and money were
changed at the same time.. but as I said above lock on a private
object don't lock on "this"
Depending on your usage you might also want to consider doing

Hi Gregory,
I tried to simplify the class and by doing that, my problem mandates a
simpler solution. Here is a more accurate version of the class:
public sealed class CCTxBatch
{
public CCTxBatch(string strTerminalId)
{
strTerminalId_ = strTerminalId;
}
pu
Yes your code will still work fine. There are however some huge
differences between this code and the original.
1) inlining will not be performed since you have put the lock in (this
will result in a (relatively) significant performance hit compared to
the original)
2) In some cases you will have
Yes, Adam, you are right. The example was derived (simplified) from my real
application. My class has a bunch of integer fields that get incremented
through various methods. I only have "get" properties for them, not because
I wanted them read-only, but because they are changed in bunches.
Anyway,
Well in this exact example, the effect is useless locking. Perhaps you have
a better example?

sql 2000 and above you can have indexed views i think, but you have to
create them through t-sql code, not the visual 'view designer'

Yes, views can be a performance problem, to do with the table scans, and
indexing (or lack thereof) when i had a huge IN statement querying my view
it caused problems, but on the actual indexed tables, no problem ...

Sorry, the get property should return "strMyField_" and not "strMyFieldId_"
as it does. Just a typo...

I want to make my class multithread safe. What's the effect of writing
something like this:
public sealed class MyClass
{
public MyClass(string strValue)
{
strMyField_ = strValue;
}
public string MyField
{

You can also build up a query as a string within your Stored procedure and
then use the EXEC function executing the string .

Guys,
I'm using SQL Server 2005 and implementing a solution where utilizing the
Xml capabilities will prove quite useful.
However, I have a question that I wanted to see if any of y'all knew or
would know where I might find some help on.

than the send in most systems (send tends to be very short lived while
receive generally lives alot longer).
As far as whether it makes a copy or not .. it appears to be pinning
