The questions are as follows:Public class BaseA{Public static MyTest a1 = new MyTest ("a1 ");Public MyTest a2 = new MyTest ("a2 ");Static BaseA (){MyTest a3 = new MyTest ("a3 ");}Public BaseA (){MyTest a4 = new MyTest ("a4 ");}Public virtual void

First, Static classThe important difference between a static class and a non-static class is that a static class cannot be instantiated, that is, a variable of a static class type cannot be created with the New keyword. Using the static keyword when

One: Pattern classificationFrom an objective point of view:Create-type (creational) mode: Responsible for object creation. Structured (Structural) mode: Handles the combination of classes and objects. Behavioral (behavioral) mode: The assignment of

Prototype chaining ): Use prototype to inherit attributes and methods. Review the relationships between constructor, prototype, and instance. Each constructor has a prototype attribute pointing to a prototype object. prototype objects also have the

C # core Foundation-class inheritance,Inheritance 　　A class can inherit from another class. In C #, only one inheritance exists between classes. That is to say, a direct base class of a class can only have one. When inheritance is implemented

First, use attributes instead of accessible fields1,. NET data binding only supports data binding, the use of attributes can obtain the benefits of data binding;2. The get and set accessors of a property can be used to add multi-threaded support

Constructor If you do not define a constructor for a class, it will automatically generate Public class sometype { } Public class sometype { Public sometype (): base (){} } The compilation results of the two sections of code are the same. If

A class file is a set of binary streams that are based on 8-byte units. Using a structure similar to the C language struct to store data, there are only two types of data: unsigned number and table. The basic data type of the unsigned number data,
