When you use the new modifier to hide a base class method, it will still be called by objects whose type is the base class. Objects whose type is the derived class will call the new method in the derived class. Dog kirby = ); // Calls Dog.Bark kirby.…

A generic class includes one or more type parameters that will be substituted with actual types when the class is used. If the class has more than one type parameter, all parameters must be substituted when the class is used. Here's an example of a g…
Polymorphism The polymorphic method call allows one type to express its distinction from another, similar type, as long as they're both derived from the same base type. Upcasting revisited Taking an object reference and treating it as a reference to…
Part 21 Inheritance in c# Why Inheritance Pillars(支架) of Object Oriented Programming 1,Inheritance(继承) 2,Encapsulation(封装) 3,Abstraction(抽象类) 4,Poymorphism(多态) 1,Inheritance is one of the primary pillars of object oriented programming. 2,It allows co…
Polymorphism is the third essential feature of an object-oriented programming language,after data abastraction and inheritance. It provides another dimension of separation of interface from implementation, to decouple what from how. Polymorphism allo…
The sysfs Filesystem | sysfs文件系统 Abstract | 摘要 sysfs is a feature of the Linux 2.6 kernel that allows kernel code to export information to user processes via an in-memory filesystem. The organization of the filesystem directory hierarchy is strict, a…
1.The Different Kinds of Type Members 1.Constants:a symbol that identifies a never-changing data value.Constants are always associated with a type, not an instance of a type. Logically, constants are always static members 2.Fields:represents a read-o…

一.Arguments 该对象代表正在执行的函数和调用他的函数的参数. [function.]arguments[n] 参数function :选项.当前正在执行的 Function 对象的名字. n :选项.要传递给 Function 对象的从0开始的参数值索引. 说明:Arguments是进行函数调用时,除了指定的参数外,还另外创建的一个隐藏对象. Arguments是个类似数组但不是数组的对象,说他类似数组是因为其具备数组相同的访问性质及方式,能够由arguments[n]来访问对应的单个…

There is a base class at the root of the hierarchy, from which the other class inherit, directly or indirectly. These inheriting classes are known as derived calsses. The key ideas in Object-Oriented Programming are data abstraction, inheritance and…
