As you can see, generic delegates offer a more flexible way to specify the method to be invoked. Under .NET 1.1, you could achieve a similar end result using a generic System.Object: public delegate void MyDelegate(object arg); Although this allows you to send any type of data to a delegate target, you do so without type safety and with possible boxing penalties. For instance, assume you have created two instances of MyDelegate, both of which point to the same method, MyTarget. Note the boxing/unboxing penalties as well as the inherent lack of type safety: class Program { static void Main(string[] args) { ... // Register target with 'traditional' delegate syntax. MyDelegate d = new MyDelegate(MyTarget); d("More string data"); // Register target using method group conversion. MyDelegate d2 = MyTarget; d2(9); // Boxing penalty. ... } // Due to a lack of type safety, we must // determine the underlying type before casting. static void MyTarget(object arg) { if(arg is int) { int i = (int)arg; // Unboxing penalty. Console.WriteLine("++arg is: {0}", ++i); } if(arg is string)

{ string s = (string)arg; Console.WriteLine("arg in uppercase is: {0}", s.ToUpper()); } } } When you send out a value type to the target site, the value is (of course) boxed and unboxed once received by the target method. As well, given that the incoming parameter could be anything at all, you must dynamically check the underlying type before casting. Using generic delegates, you can still obtain the desired flexibility without the issues.

This first chapter introduces you to the technologies that we are going to use in this book, including Java, Flex, Spring, and Hibernate, as well as the benefits of object-oriented programming over procedural or scripting languages, and of a lightweight programming approach.

I ll wrap up this chapter by covering one final aspect regarding generic delegates. As you know, delegates may be nested within a class type to denote a tight association between the two reference types. If the nesting type is a generic, the nested delegate may leverage any type parameters in its definition: // Nested generic delegates may access // the type parameters of the nesting generic type. public class MyList<T> { private List<T> listOfData = new List<T>(); public delegate void ListDelegate(T arg); }

Generics can arguably be viewed as the major enhancement provided by C# 2005. As you have seen, a generic item allows you to specify placeholders (i.e., type parameters) that are specified at the time of creation (or invocation, in the case of generic methods). Essentially, generics provide a solution to the boxing and type-safety issues that plagued .NET 1.1 development. While you will most often simply make use of the generic types provided in the .NET base class libraries, you are also able to create your own generic types. When you do so, you have the option of specifying any number of constraints to increase the level of type safety and ensure that you are performing operations on types of a known quantity.

The solution is to edit the .flexProperties file located in the root of your project, as shown in Figure 9-21.

ach of the applications developed in this book s first ten chapters were along the lines of traditional stand-alone applications, given that all of your custom programming logic was contained within a single executable file (*.exe). However, one major aspect of the .NET platform is the notion of binary reuse, where applications make use of the types contained within various external assemblies (aka code libraries). The point of this chapter is to examine the core details of creating, deploying, and configuring .NET assemblies. In this chapter, you ll first learn the distinction between single-file and multifile assemblies, as well as private and shared assemblies. Next, you ll examine exactly how the .NET runtime resolves the location of an assembly and come to understand the role of the Global Assembly Cache (GAC), application configuration files (*.config files), publisher policy assemblies, and the System.Configuration namespace.

.NET applications are constructed by piecing together any number of assemblies. Simply put, an assembly is a versioned, self-describing binary file hosted by the CLR. Now, despite the fact that .NET assemblies have exactly the same file extensions (*.exe or *.dll) as previous Win32 binaries (including legacy COM servers), they have very little in common under the hood. Thus, to set the stage for the information to come, let s ponder some of the benefits provided by the assembly format.
