This enables developers to provide the custom error checking that each API uses while still reporting the error in a standard manner Listing 171 and Listing 173 declared the P/Invoke methods as internal or private Except for the simplest of APIs, wrapping methods in public wrappers that reduce the complexity of the P/Invoke API calls is a good guideline that increases API usability and moves toward object-oriented type structure The AllocExecutionBlock() declaration in Listing 176 provides a good example of this

Performing an Inner Join with Join() In the world of objects on the client side, relationships between objects are generally already set up For example, the relationship between files and the directories in which they lie are preestablished with the DirectoryInfoGetFiles() method and the FileInfoDirectory method Frequently, however, this is not the case with data being loaded from nonobject stores Instead, the data needs to be joined together so that you can navigate from one type of object to the next in a way that makes sense for the data Consider the example of employees and company departments In Listing 1421, we join each employee to his or her department and then list each employee with his or her corresponding department Since each employee belongs to only one (and exactly one) department, the total number of items

Frequently, P/Invoke involves a resource, such as a window handle, that code needs to clean up after using it Instead of requiring developers to remember this and manually code it each time, it is helpful to provide a class that implements IDisposable and a finalizer In Listing 177, for example, the address returned after VirtualAllocEx() and VirtualProtectEx() requires a follow-up call to VirtualFreeEx() To provide built-in support for this, you define a VirtualMemoryPtr class that derives from SystemRuntimeInteropServicesSafeHandle (this is new in NET 20)

in the list is equal to the total number of employees each employee appears only once (each employee is said to be normalized) Output 148 follows

public classVirtualMemoryPtr : SystemRuntimeInteropServicesSafeHandle { public VirtualMemoryPtr(int memorySize) : base(IntPtrZero, true) { ProcessHandle = VirtualMemoryManagerGetCurrentProcessHandle(); MemorySize = (IntPtr)memorySize; AllocatedPointer = VirtualMemoryManagerAllocExecutionBlock( memorySize, ProcessHandle); Disposed = false; } public readonly IntPtr AllocatedPointer; readonly IntPtr ProcessHandle; readonly IntPtr MemorySize; bool Disposed; public static implicit operator IntPtr( VirtualMemoryPtr virtualMemoryPointer) { return virtualMemoryPointerAllocatedPointer; } // SafeHandle abstract member public override boolIsInvalid {

Listing 1421: An Inner Join Using SystemLinqEnumerableJoin()

using System; using SystemLinq; // Department[] departments = CorporateDataDepartments; Employee[] employees = CorporateDataEmployees; var items = employeesJoin( departments, employee => employeeDepartmentId, department => departmentId, (employee, department) => new { employeeId, employeeName, employeeTitle, Department = department }); foreach (var item in items) { ConsoleWriteLine("{0} ({1})", itemName, itemTitle); ConsoleWriteLine("\t" + itemDepartment); } //
