As Listing 1416 shows, the change in code to enable parallel support is minimal All that it uses is a NET Framework 4 introduced standard query operator, AsParallel(), on the static class SystemLinqParallelEnumerable Using this simple extension method, however, the runtime begins executing over the items within the fileList collection and returning the resultant objects in parallel Each parallel operation in this case isn t particularly expensive (although it is relative to what other execution is taking place), but consider CPU-intensive operations such as encryption or compression Paralyzing the execution across multiple CPUs can decrease execution time by a magnitude corresponding to the number of CPUs An important caveat to be aware of (and the reason why AsParallel() appears in an Advanced Block rather than the standard text) is that parallel execution can introduce race conditions such that an operation on one thread can be intermingled with an operation on a different thread, causing data corruption To avoid this, synchronization mechanisms are required on data with shared access from multiple threads in order to force the operations to be atomic where necessary Synchronization itself, however, can introduce deadlocks that freeze the execution, further complicating the effective parallel programming More details on this and additional multithreading topics are covered in 18 and 19

In this case, the class is VirtualMemoryManager, because it will contain functions associated with managing memory (This particular function is available directly off the SystemDiagnosticsProcessor class, so there is no need to declare it in real code)

Counting Elements with Count() Another common query performed on a collection of items is to retrieve the count To support this LINQ includes the Count() extension method Listing 1417 demonstrates that Count() is overloaded to simply count all elements (no parameters) or to take a predicate that only counts items identified by the predicate expression

attribute, which accompanies the method declaration, points to the implementation At a minimum, the attribute needs the name of the DLL that defines the function The runtime determines the function name from the method name However, it is possible to override this default using the EnTRyPoint named parameter to provide the function name (The NET platform will automatically attempt calls to the Unicode [W] or ASCII [A] API version) It this case, the external function, GetCurrentProcess(), retrieves a pseudohandle for the current process which you will use in the call for virtual memory allocation Here's the unmanaged declaration: HANDLE GetCurrentProcess();

} Each of the cases firstcase, secondcase, thirdcase and so on can be integers or characters The statements that are associated with each case can be a single statement or a compound statement

Assuming the developer has identified the targeted DLL and exported function, the most difficult step is identifying or creating the managed data types that correspond to the unmanaged types in the

In spite of the simplicity of writing the Count() statement, IEnumerable<T> has not changed, so the executed code still involves iterating over all the items in the collection Whenever a Count property is directly available on the collection, it is preferable to use that rather than LINQ s Count() method (a subtle difference) Fortunately, ICollection<T> includes the Count property, so code that calls the Count() method on a collection that supports ICollection<T> will cast the collection and call Count directly However, if ICollection<T> is not supported, EnumerableCount() will proceed to enumerate all the items in the collection rather than call the built-in Count mechanism If the purpose of checking the count is only to see whether it is greater than zero (if(patentsCount() > 0){}), a preferable approach would be to use the Any() operator (if(patentsAny()){}) Any() attempts to iterate over only one of the items in the collection to return a true result, rather than the entire sequence

One particularly helpful resource for declaring Win32 APIs is wwwpinvokenet This provides a great starting point for many APIs, helping to avoid some of the subtle problems that can arise when coding an external API call from scratch

Deferred Execution One of the most important concepts to remember when using LINQ is deferred execution Consider the code in Listing 1418 and the corresponding output in Output 145
