Note that base classes do not contribute to the declaration space of a class, and base interfaces do not contribute to the declaration space of an interface. Thus, a derived class or interface is allowed to declare a member with the same name as an inherited member. Such a member is said to hide the inherited member. Each enumeration declaration creates a new declaration space. Names are introduced into this declaration space through enummemberdeclarations. Each block or switchblock creates a separate declaration space for local variables. Names are introduced into this declaration space through localvariabledeclarations. If a block is the body of a constructor or method declaration, the parameters declared in the formalparameterlist are members of the block’s local variable declaration space. The local variable declaration space of a block includes any nested blocks. Thus, within a nested block it is not possible to declare a local variable with the same name as a local variable in an enclosing block. Each block or switchblock creates a separate declaration space for labels. Names are introduced into this declaration space through labeledstatements, and the names are referenced through gotostatements. The label declaration space of a block includes any nested blocks. Thus, within a nested block it is not possible to declare a label with the same name as a label in an enclosing block. The textual order in which names are declared is generally of no significance. In particular, textual order is not significant for the declaration and use of namespaces, types, constants, methods, properties, events, indexers, operators, constructors, destructors, and static constructors. Declaration order is significant in the following ways: Declaration order for field declarations and local variable declarations determines the order in which their initializers (if any) are executed. Local variables must be defined before they are used. Declaration order for enum member declarations is significant when constantexpression values are omitted. The types of the C language are divided into three categories: Value types, reference types, and 本科畢業(yè)設(shè)計(jì)（論文）外文翻譯 6 pointer types. type: ? valuetype ? referencetype ? pointertype Pointer types can be used only in unsafe code. Value types differ from reference types in that variables of the value types directly contain their data, whereas variables of the
