Virtual method (virtual method)The virtual keyword is used to decorate a method in a base class. There are two things you can do with virtual:Scenario 1: The virtual method is defined in the base class, but the virtual method is not overridden in the derived class. In a call

The project uses interfaces to define the concepts of classes, Operation classes, and abstract classes! The class is responsible for the specific implementation of the function! There are also abstract class definitions in the class. The difference between the abstract class and the inte

Anonymous method, c # anonymous methodAnonymous Method In versions earlier than C #2.0, the only way to create a delegate is to use the naming method. Anonymous methods have been introduced since C #2.0. in

The definition of polymorphism in C # is that the same operation works on instances of different classes, different classes are interpreted differently, and results are different. In other words, an interface, multiple functions. C # supports 2 forms of polymorphism: compile-time polymorphism, run-time polymorphism Compile-time polymorphism: Compile-time polymorphism is implemented by overloading

Objective-C notes Class 2, object and method, objective-c notes An object is an object. Object-Oriented programming can be seen as an object and what you want to do with it. This is different from the C language, which is usually called a procedural language. In C language,

Extension Method, c # Extension Method The extension method enables you to "add" methods to existing types without creating a new derived type, re-compiling, or modifying the original type in other ways. An extension method is a special static

extension MethodsThe extension method has several requirements: You want to add some members to a type; You do not need to add any more data to an instance of the type; You can't change the type itself, because it's someone else's code. For static methods in C#1 and c#2, the extension method is a

At this point, B does not point to any valid instance, the value is null, and the relevant code is:b b;2) Next, the creation of the object is performed by new, namely:b =new B ();object is saved on the managed heap, and the CLR creates a new object while creating itstype Object(If the type object does not exist).　　The memory of an object instance in the heap includes an instance field, a type object pointer, a synchronous index block, and a type object pointer to a type object.　　The mem
