In this chapter, I will introduce information that is fundamental to working with types and the common language runtime (CLR) . In particular, I ll discuss the minimum set of behaviors that you can expect every type to have . I ll also describe type safety, namespaces, assemblies, and the various ways you can cast objects from one type to another . Finally, I ll conclude this chapter with an explanation of how types, objects, thread stacks, and the managed heap all relate to one another at runtime .

The runtime requires every type to ultimately be derived from the System.Object type . This means that the following two type definitions are identical:

Because all types are ultimately derived from System.Object, you are guaranteed that every object of every type has a minimum set of methods . Specifically, the System.Object class offers the public instance methods listed in Table 4-1 .

Public Methods of System.Object
Description
Returns true if two objects have the same value . For more information about this method, see the Object Equality and Identity section in 5, Primitive, Reference, and Value Types . Returns a hash code for this object s value . A type should override this method if its objects are to be used as a key in a hash table collection . The method should provide a good distribution for its objects . It is unfortunate that this method is defined in Object because most types are never used as keys in a hash table; this method should have been defined in an interface . For more information about this method, see the Object Hash Codes section in 5 . By default, returns the full name of the type (this.GetType().FullName) . However, it is common to override this method so that it returns a String object containing a representation of the object s state . For example, the core types, such as Boolean and Int32, override this method to return a string representation of their values . It is also common to override this method for debugging purposes; you can call it and get a string showing the values of the object s fields . In fact, Microsoft Visual Studio s debugger calls this function automatically to show you a string representation of an object . Note that ToString is expected to be aware of the CultureInfo associated with the calling thread . 14, Chars, Strings, and Working with Text, discusses ToString in greater detail . Returns an instance of a Type-derived object that identifies the type of the object used to call GetType . The returned Type object can be used with the reflection classes to obtain metadata information about the object s type . Reflection is discussed in 23, Assembly Loading and Reflection . The GetType method is nonvirtual, which prevents a class from overriding this method and lying about its type, violating type safety .
