Here, CompareExchange changes the NewMail reference to null if it is null and does not alter NewMail if it is not null . In other words, CompareExchange doesn t change the value in NewMail at all, but it does return the value inside NewMail in an atomic, thread-safe way . See 28, Primitive Thread Synchronization Constructs, for more information about the Thread.VolatileRead and Interlocked . CompareExchange methods . While the fourth version of this code is the best, technically correct version, you can actually use the second version because the just-in-time (JIT) compiler is aware of this pattern and it knows not to optimize away the local temp variable . Specifically, all of Microsoft s JIT compilers respect the invariant of not introducing new reads to heap memory and therefore, caching a reference in a local variable ensures that the heap reference is accessed only once . This is not documented and, in theory, it could change, which is why you should use the fourth version . But in reality, Microsoft s JIT compiler would never embrace a change that would break this pattern because too many applications would break .1 In addition, events are mostly used in single-threaded scenarios (Windows Forms, Windows Presentation Foundation, and Microsoft Silverlight) and so thread safety is not an issue anyway . It is very important to note that due to this thread race condition, it is also possible that a method will be invoked after it has been removed from the event s delegate chain . As a convenience, you could define an extension method (as discussed in 8, Methods ) that encapsulates this thread-safety logic . Define the extension method like this:

The application shown in Figure 8-2 uses the schema we analyzed in the section "The FOR XML EXPLICIT Mode," on page 356, while examining the FOR XML EXPLICIT clause. The application runs the same SELECT command we used in that section and then walks its way through the result set using an XML reader. The information read is used to fill up a treeview control.

The default proxy for all WebRequest instances is configured using the System.Net.GlobalProxySelection class. The WebRequest.Proxy property enables the proxy to be set on a per-request basis, overriding the global default. The following example demonstrates the setting of a default proxy:

There is a big assumption being made with the code above: no errors occur . But, of course, errors are always possible, and so we need a way to handle those errors . This is what the exception handling constructs and mechanisms are all about and why we need them as opposed to having methods that return true/false to indicate success/failure the way that Win32 and COM functions do . In addition to code composability, we are productive due to all kinds of great features provided by our compilers . For example, the compiler implicitly:

The ConvertIList method specifies two type parameters in which the T parameter is constrained by the TBase type parameter . This means that whatever type argument is specified for T, the type argument must be compatible with whatever type argument is specified for TBase . Here is a method showing some legal and illegal calls to ConvertIList:

The query returns all 91 customers. Because there's no distinction between an ON clause and a WHERE clause, I specified both expressions in the WHERE clause separated by the logical operator AND. You have no control over which part of the filter will take place before adding the outer rows and which part will take place afterwards. That's at the sole discretion of SQL Server. By looking at the result, you can guess what SQL Server did. Logically, it applied the whole expression before adding outer rows. Obviously, there's no row in the Cartesian product for which C.CustomerID = O.CustomerID and O.CustomerID IS NULL. So the second phase in query logical processing yields an empty set. The third phase adds outer rows for rows from the preserved table (Customers) with no match. Because none of the rows matched the join condition, all customers are added back as outer rows. That's why this query returned all 91 customers. Bearing in mind that you got this surprising result because both expressions were applied before adding the outer rows, and being familiar with query logical processing, there is a way to "fix" the problem. Remember that there's another filter available to you in a querythe HAVING filter. First write a join query without the filter to isolate outer rows. Even though the rows in the result of the join are unique, group them by all columns to allow the query to include a HAVING clause. Then put the filter that isolates the outer rows into the HAVING clause: SELECT C.CustomerID, CompanyName, OrderID FROM dbo.Customers AS C, dbo.Orders AS O WHERE C.CustomerID *= O.CustomerID GROUP BY C.CustomerID, CompanyName, OrderID HAVING OrderID IS NULL;
