8 ❘ ChaPTer 1 .net Architecture This is all quite an ambitious aim, but amazingly, .NET and IL have achieved it. In the case of stepping between methods in the debugger, this facility is really offered by the Visual Studio integrated development environment (IDE) rather than by the CLR itself. distinct Value and reference Types As with any programming language, IL provides a number of predefined primitive data types. One characteristic of IL, however, is that it makes a strong distinction between value and reference types. Value types are those for which a variable directly stores its data, whereas reference types are those for which a variable simply stores the address at which the corresponding data can be found. In C++ terms, using reference types is similar to accessing a variable through a pointer, whereas for Visual Basic, the best analogy for reference types are objects, which in Visual Basic 6 are always accessed through references. IL also lays down specifications about data storage: instances of reference types are always stored in an area of memory known as the managed heap, whereas value types are normally stored on the stack (although if value types are declared as fields within reference types, they will be stored inline on the heap). Chapter 2, “Core C#,” discusses the stack and the heap and how they work. strong data Typing One very important aspect of IL is that it is based on exceptionally strong data typing. That means that all variables are clearly marked as being of a particular, specific data type (there is no room in IL, for example, for the Variant data type recognized by Visual Basic and scripting languages). In particular, IL does not normally permit any operations that result in ambiguous data types. For instance, Visual Basic 6 developers are used to being able to pass variables around without worrying too much about their types, because Visual Basic 6 automatically performs type conversion. C++ developers are used to routinely casting pointers between different types. Being able to perform this kind of operation can be great for performance, but it breaks type safety. Hence, it is permitted only under certain circumstances in some of the languages that compile to managed code. Indeed, pointers (as opposed to references) are permitted only in marked blocks of code in C#, and not at all in Visual Basic (although they are allowed in managed C++). Using pointers in your code causes it to fail the memory type-safety checks performed by the CLR. You should note that some languages compatible with .NET, such as Visual Basic 2010, still allow some laxity in typing, but that it’s possible only because the compilers behind the scenes ensure that the type safety is enforced in the emitted IL. Although enforcing type safety might initially appear to hurt performance, in many cases the benefits gained from the services provided by .NET that rely on type safety far outweigh this performance loss. Such services include the following: ➤ ➤ ➤ ➤ Language interoperability Garbage collection Security Application domains The following sections take a closer look at why strong data typing is particularly important for these features of .NET. strong Data Typing as a Key to language interoperability If a class is to derive from or contains instances of other classes, it needs to know about all the data types used by the other classes. This is why strong data typing is so important. Indeed, it is the absence of any agreed-on system for specifying this information in the past that has always been the real barrier to inheritance and interoperability across languages. This kind of information is simply not present in a standard executable file or DLL. www.it-ebooks.info
a Closer look at intermediate language ❘ 9 Suppose that one of the methods of a Visual Basic 2010 class is defined to return an Integer — one of the standard data types available in Visual Basic 2010. C# simply does not have any data type of that name. Clearly, you will be able to derive from the class, use this method, and use the return type from C# code, only if the compiler knows how to map Visual Basic 2010s Integer type to some known type that is defined in C#. So, how is this problem circumvented in .NET Common Type System This data type problem is solved in .NET using the Common Type System (CTS). The CTS defines the predefined data types that are available in IL, so that all languages that target the .NET Framework will produce compiled code that is ultimately based on these types. For the previous example, Visual Basic 2010s Integer is actually a 32-bit signed integer, which maps exactly to the IL type known as Int32. Therefore, this will be the data type specified in the IL code. Because the C# compiler is aware of this type, there is no problem. At source code level, C# refers to Int32 with the keyword int, so the compiler will simply treat the Visual Basic 2010 method as if it returned an int. The CTS does not specify merely primitive data types but a rich hierarchy of types, which includes welldefined points in the hierarchy at which code is permitted to define its own types. The hierarchical structure of the CTS reflects the single-inheritance object-oriented methodology of IL, and resembles Figure 1-1. Type Reference Type Interface Types Built-in Value Types Value Type User-defined Value Types Pointer Types Class Types Self-describing Types Arrays Enumerations Delegates Boxed Value Types User-defined Reference Types figure 1-1 We will not list all the built-in value types here, because they are covered in detail in Chapter 3, “Objects and Types.” In C#, each predefined type is recognized by the compiler maps onto one of the IL built-in types. The same is true in Visual Basic 2010. Common Language Specification The Common Language Specification (CLS) works with the CTS to ensure language interoperability. The CLS is a set of minimum standards that all compilers targeting .NET must support. Because IL is a very rich language, writers of most compilers will prefer to restrict the capabilities of a given compiler to support only a subset of the facilities offered by IL and the CTS. That is fine, as long as the compiler supports everything that is defined in the CLS. For example, take case sensitivity. IL is case-sensitive. Developers who work with case-sensitive languages regularly take advantage of the flexibility that this case sensitivity gives them when selecting variable names. Visual Basic 2010, however, is not case-sensitive. The CLS works around this by indicating that CLScompliant code should not expose any two names that differ only in their case. Therefore, Visual Basic 2010 code can work with CLS-compliant code. www.it-ebooks.info
